Most Recent Developments

On December 22, 2006, President Bush signed P.L. 109-449 ( S. 362 ), establishing NOAA and Coast Guard programs to manage marine debris and address its adverse effects on endangered species. On December 9, 2006, the Senate agreed to the House-amended S. 362 . On December 9, 2006, the House passed the Senate-amended H.R. 5946 . On December 7, 2006, the Senate passed H.R. 5946 , amended to incorporate language (1) requiring a study of sea turtle excluder devices in shrimp trawls, and (2) implementing the Agreement on the Conservation and Management of the Alaska-Chukotka Polar Bear Population. On December 6, 2006, the Senate passed H.R. 4075 , after amending this bill to incorporate language implementing the Agreement on the Conservation and Management of the Alaska-Chukotka Polar Bear Population.

	Background and Analysis

		Overview

The 1973 ESA ( P.L. 93-205 , as amended; 16 U.S.C. §§1531-1543) was a comprehensive attempt to protect species at risk of extinction and to consider habitat protection as an integral part of that effort. A stated purpose of the ESA is to protect the ecosystems of which listed species are a part. Under the ESA, species of plants and animals (both vertebrate and invertebrate) may be listed as either endangered or threatened according to assessments of the risk of their extinction. More flexible management can be provided for species listed as threatened. Distinct population segments may also be listed as threatened or endangered, but only of vertebrate species. Consequently, some populations of chinook, coho, chum, and sockeye salmon in Washington, Oregon, Idaho, and California are protected under the ESA, even as other healthy populations of these same species in Alaska are not listed and may be commercially harvested. More limited protection is available for plant species under the ESA. Once a species is listed, powerful legal tools, including penalties and citizen suits, are available to aid species recovery and protect habitat. Use of these tools, or the failure to use them, has led to conflict.
The ESA is administered by the Department of the Interior's Fish and Wildlife Service (FWS) for terrestrial and freshwater species and some marine mammals, and by the National Marine Fisheries Service (NMFS; also popularly referred to as NOAA Fisheries) in the Department of Commerce's National Oceanic and Atmospheric Administration (NOAA) for the remaining marine and anadromous species. The U.S. Geological Survey's Biological Resources Division conducts research on species for which FWS has management authority; NMFS conducts research on the species for which it is responsible.
As of September 20, 2006, a total of 1,132 species of animals and 747 species of plants had been listed as either endangered or threatened, of which the majority (567 species of animals and 744 species of plants) occur in the United States and its territories and the remainder only in other countries. Of the 1,311 U.S. species (an increase of 49 species since December 31, 2002), 1,070 are covered in recovery plans (an increase of 70 species since December 31, 2002). Of the U.S. species, 475 have designated critical habitat (CH) in some portion of their range.
At times, efforts to protect and recover listed species are controversial; declining species often function like the proverbial canary in the coal mine, by flagging larger issues of resource scarcity and altered ecosystems. Past resource debates in which ESA-listed species were part of larger issues include Tennessee's Tellico Dam (water storage and construction jobs versus farmland protection and tribal graves, as well as snail darters); Pacific northwest timber harvest (protection of logging jobs and communities versus commercial and sport fishing, recreation, and ecosystem protection, as well as salmon and spotted owls); and Texas's Edwards Aquifer (allocation of water among various users with differing short- and long-term interests, as well as several spring-dependent species).

		Major Provisions of Domestic Law

			Listing

Species may be listed on the initiative of the appropriate Secretary or by petition from an individual, group, or state agency. The Secretary must decide whether to list the species based only on the best available scientific and commercial information, after an extensive series of procedural steps to ensure public participation and the collection of scientific information. In deciding whether a species needs the protections of the ESA, the Secretary may not take into account the economic effects that listing may have; economic and other considerations are taken into account in structuring alternatives for assisting the species after listing.
In addition, FWS and NMFS may identify selected species by adding them to a list of "candidate species" believed at sufficient risk to warrant protection, but such protection is precluded by work to protect listed species. As of September 13, 2006, there were 279 species on the list of candidate species.

			Critical Habitat

With certain exceptions, if a species is listed, the Secretary must designate critical habitat (CH) in areas where the species is currently found or which might provide additional habitat for the species' recovery. However, if the publication of this information is not prudent (e.g., might encourage vandals or collectors), the Secretary may decide not to designate CH. The Secretary may postpone designation for up to one year after listing, if the information is not determinable (16 U.S.C. §1533). As of June 16, 2006, FWS had designated CH for 36% of listed domestic species.
As a practical matter, CH has not been designated for most listed species largely because FWS prefers to allocate its limited resources to listing new species, based on its regulation (50 C.F.R. §402.02) that takes away much of the legal value of designating CH to the recovery of the species. Yet FWS consistently loses legal challenges for failure to designate CH, and several courts have found the regulation in question to be an erroneous interpretation of the law, because it does not take into account the duty to avoid adverse modification of CH. Others have asserted the value of CH; for example, scientists with the Center for Biological Diversity published a study in April 2005, concluding that CH designation enhances species recovery. On April 28, 2006, the Keystone Center's ESA Working Group on Habitat released a report on habitat protection and the ESA. One of the conclusions of participants in this study was that identification of the habitat that species require to recover is better done in the context of recovery planning, after more rigorous analysis and deliberation have been completed, rather than at the time of listing.
CH is frequently misunderstood by the public as posing a significant direct restriction on private landowners' authority to manage land. While a landowner may experience some additional procedures and possible restrictions on land management because of the presence of an ESA-listed species (through the ESA's prohibitions on taking a listed species), and the presence of CH may shed light on whether "harm" has occurred, the duty to avoid adverse modification of CH is an express obligation only for federal agencies and actions, or private (nonfederal) actors in actions with a federal nexus (i.e., actions that involve any federal funding, permit, or license). (See also " Issues in the 109 th Congress ," below.)

			Prohibitions and Penalties

The ESA contains prohibitions on the "take" of endangered species; take means to "harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect or attempt to engage in any such conduct" (16 U.S.C. §1532; harassment and harm are further defined in regulation at 50 C.F.R. §17.3). There has been controversy over the extent to which habitat modification is prohibited. A 1995 Supreme Court decision held that the inclusion of significant habitat modification was a reasonable interpretation of the term "harm" in the ESA. The ESA provides civil and criminal penalties for violations.

			Permits and Consultation

Proposed actions that may have adverse impacts on listed species may be permitted in two ways. First, under §7 of the ESA, if federal agency actions (or actions of a nonfederal party that require an agency's approval, permit, or funding) may affect a listed species, the federal agency must ensure that those actions are "not likely to jeopardize the continued existence" of any endangered or threatened species, nor to destroy or adversely modify CH. To review the possible effects of their actions on listed species and CH, federal agencies must consult with the appropriate Secretary. If the Secretary finds that an action would jeopardize a listed species or destroy or adversely modify CH, the Secretary must suggest reasonable and prudent alternatives that would avoid these harms. Pending completion of the consultation process, agencies may not make irretrievable commitments of resources that would foreclose any alternatives. The Secretary issues a written statement, called a biological opinion , that may allow the agency or the applicant to take individuals of a species incidental to otherwise lawful activities without triggering the ESA's penalties, subject to terms and conditions specified in the opinion (16 U.S.C. §1536), or may conclude that jeopardy cannot be avoided, in which case the agency may seek an exemption for the action from the Endangered Species Committee.
For actions without a federal nexus (i.e., no federal funding, permit, or license), the appropriate Secretary may issue permits under §10 of the ESA to allow the incidental take of species during otherwise lawful actions. An applicant for a permit must submit a habitat conservation plan (HCP) that shows the likely impact of the planned action; steps to be taken to minimize and mitigate the impact; funding for the mitigation; alternatives that were considered and rejected; and any other measures that the Secretary may require. The use of this section has been vastly expanded, and streamlined procedures are provided for activities with minimal impacts (50 C.F.R. §17.22).

			Exemptions

Proponents of a federal action may apply for an exemption from the prohibition against jeopardy for that action (not for a species). Under the ESA, a high-level Endangered Species Committee (commonly called the "God Squad") decides whether to allow a project to proceed despite likely harm to a species. To date, this process has been little used and only one exemption (Grayrocks Dam, WY) has been granted and carried out. The committee is required to accept the President's determination (under specified circumstances) on an exemption in declared disaster areas. The ESA committee must grant an exemption if the Secretary of Defense determines that an exemption is necessary for national security (16 U.S.C. §1536). DOD has claimed that requirements under the ESA conflict with its readiness activities, but DOD has not requested any exemptions to date. (See also " Issues in the 109 th Congress ," below.) Other statutes may provide for waivers of ESA provisions; for example, §102(c) of the Illegal Immigration Reform and Immigrant Responsibility Act of 1996 provides for a waiver of the ESA (and NEPA) to the extent the Attorney General determines is necessary to ensure expeditious construction of barriers and roads at borders.
In the 109 th Congress, §2(b) of H.R. 3693 would have waived ESA provisions to the extent the Secretary of Homeland Security deemed necessary to prevent illegal border crossings. In addition, Section 2(b)(2)(A) of H.R. 5235 asserted that P.L. 108-148 , the Healthy Forests Restoration Act of 2003, exempted certain actions by federal land management agencies from ESA consultation and would require a National Academy of Sciences study of the impacts of P.L. 108-148 . Section 3 of H.R. 5678 would have waived ESA review and consultation for certain pipeline repair and replacement activities where best practices have been developed or adopted by an interagency committee.

			Emergencies

50 C.F.R. §402.05 provides for ESA procedures in case of emergencies, basically requiring only very informal consultations during an emergency with more complete consultation after the emergency has passed. According to FWS, any hurricane-related federal activities in presidentially declared disaster areas would trigger the emergency consultation provisions of the ESA. Specifically, for the 2005 Gulf of Mexico hurricanes, FWS stated that restoring "any infrastructure damaged or lost due to the hurricane back into the original footprint does not require ESA consultation with the Service." In the 109 th Congress, S. 2079 / H.R. 4200 would have authorized emergency procedures to comply with ESA §7 for pre-approved management practices for federal land damaged by a catastrophe (§104(e)) and for catastrophic event research and recovery projects (§105(c)). The House passed H.R. 4200 (amended) on May 17, 2006. The Senate Agriculture Committee's Subcommittee on Forestry, Conservation, and Rural Revitalization held a hearing on H.R. 4200 on August 2, 2006.

			Recovery Plans

The appropriate Secretary generally must develop a recovery plan for the survival and conservation (defined in §3(3) of the ESA as "to bring any endangered species or threatened species to the point at which the measures provided pursuant to this Act are no longer necessary"—i.e., recovery) of a listed species; these plans are not binding on federal agencies or others, but rather serve as guidelines. At first, recovery plans tended to cover popular species, like birds or mammals, but a 1988 amendment forbade the Secretary from favoring particular taxonomic groups (16 U.S.C. §1533).

			Land Acquisition and Cooperation

The federal government may acquire land to conserve/recover listed species, and the ESA authorizes money from the Land and Water Conservation Fund for land acquisition (16 U.S.C. §1534). The appropriate Secretary must cooperate with the states in conserving protected species and must enter into cooperative agreements to assist states in their endangered species programs, if the programs meet certain specified standards. If there is a cooperative agreement, the states may receive federal funds to implement the program, but must normally provide a minimum 25% match. Under the 1988 amendments, the Cooperative Endangered Species Conservation Fund was authorized to provide state grants. While regular annual deposits to this fund are set by a formula (16 U.S.C. §1535(i)(1)), spending from the fund requires annual appropriation.

			Miscellaneous

Other provisions specify exemptions for certain captive raptors and their progeny, regulate subsistence activities by Alaskan Natives, prohibit interstate transport and sale of listed species and parts, control trade in parts or products of endangered species owned before the ESA went into effect, and specify rules for establishing experimental populations (16 U.S.C. §1539).

		Major Provisions of International Law

For the United States, the ESA is the domestic implementing legislation for the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES; TIAS 8249), signed by the United States on March 3, 1973; and the Convention on Nature Protection and Wildlife Preservation in the Western Hemisphere (the Western Hemisphere Convention; 50 Stat. 1354; TS 981), signed by the United States on October 12, 1940. CITES parallels the ESA by dividing its listed species into groups, according to the estimated risk of extinction, but uses three major categories (called Appendices), rather than two. In contrast to the ESA, CITES classifies species based solely on the risk that trade poses to their survival. The ESA makes violations of CITES violations of U.S. law if committed within U.S. jurisdiction (16 U.S.C. §1538). The ESA also regulates import and export of controlled products and provides some exceptions.
On August 18, 2003, FWS published a draft policy for enhancement-of-survival permits for foreign species listed under the ESA. The permits would allow imports of endangered species into the United States for scientific research and for the enhancement of survival of the species in their range country (i.e., the country where the population of the species in question naturally exists). The comment period on this draft policy has closed, but FWS has not yet published its final policy.
In addition, the Multinational Species Conservation Fund (MSCF) in FWS benefits tigers, the six species of rhinoceroses, Asian and African elephants, marine turtles, and great apes (gorillas, chimpanzees, bonobos, orangutans, and the various species of gibbons). This fund supports conservation efforts benefitting these species, often in conjunction with efforts under CITES.
In the 109 th Congress, P.L. 109-363 reauthorized and amended the Neotropical Migratory Bird Conservation Act ( P.L. 106-247 ; 16 U.S.C. §§6101 et seq.) to increase the federal share of costs for projects funded (Title III) and reauthorized the Great Ape Conservation Act of 2000 ( P.L. 106-411 ; 16 U.S.C. §§6301 et seq.) to provide grants and emergency assistance to address conservation needs (Title VII). A number of other bills were considered in the 109 th Congress:
Several bills would have expanded species eligible for assistance from the MSCF by creating a Flagship Species Conservation Fund ( H.R. 93 ), a Great Cats and Rare Canids Conservation Fund ( H.R. 1707 ), and a Crane Conservation Fund ( S. 943 / H.R. 3520 ). S. 270 would have established a framework for legislative and executive consideration of unilateral economic sanctions against foreign nations, such as could be imposed in relationship to CITES. H.R. 3469 would have provided measures to improve the conservation of coral reef species and further the obligations of the United States under CITES.

		Is Species Protection and Restoration Working?

The answer to this question depends on what is measured. Since a major goal of the ESA is the recovery of species to the point at which ESA protection is no longer necessary, this seems a good starting point. Since the ESA was enacted in 1973, 40 U.S. and foreign species have been delisted. The reasons cited by FWS are (a) recovery (17); (b) extinction (9, but some may have been extinct when listed); (c) new understanding of the taxonomy of the species, making some ineligible for listing under current law (7); and (d) new information, including a determination that erroneous data were provided to FWS at the time of listing (7). Recovered species include alligators, peregrine falcons (two subspecies), and three species of kangaroos. Extinct species include the dusky seaside sparrow, Guam broadbill (a bird), and two small fish living in desert springs. However, it can be quite difficult to prove whether extraordinarily rare species are simply that or, in fact, are already extinct. For example, a rare shorebird thought by many to be extinct was rediscovered in a remote area of Canada a few years ago; it might just as easily have quietly gone extinct without being rediscovered. Rare species are, by definition, hard to find.
Some have asserted that the ESA is a failure since only 17 species have been delisted as recovered, as of January 25, 2006. Others note that full recoveries are relatively few because the two principal causes of extinction—habitat loss and invasive non-native species—are increasing. In addition, some scientific studies have demonstrated that most species are listed only after they become very depleted (e.g., median population of 407 animals for endangered vertebrates, according to one study), thereby making recovery difficult. Another measure of "success" might be the number of species that have stabilized or increased their populations, even if the species are not actually delisted. If this standard is used, the ESA could be considered a success, since a large number (41%, according to one study) of listed species have improved or stabilized their population levels after listing. Other species (e.g., red wolves and California condors) might not exist at all without ESA protection, and this too might be considered a measure of success, although these species are still rare.
On May 17, 2005, the House Committee on Resources released an oversight report entitled Implementation of the Endangered Species Act of 1973 . It reviewed and critiqued various ways that recovery might be measured. One approach is to look at what proportion of the recovery objectives identified in species recovery plans have been achieved. Table 1 indicates how recovery has progressed related to the length of time since species were listed.
On September 8, 2006, GAO released report GAO-06-730, entitled Endangered Species: Many Factors Affect the Length of Time to Recover Select Species . This report examined federal efforts to recover a nonprobability sample of 31 species. GAO determined that, while many factors affected the recovery of species, recovery plans played an important role in the recovery of all but one of the species examined. Critics claimed the GAO study was biased by the selection of species examined.

	Issues in the 109th Congress

ESA reauthorization has been on the legislative agenda since the funding authorization expired in 1992, and bills have been introduced in each subsequent Congress to address various aspects of endangered species protection. The issues considered in the 109 th Congress included effects of the ESA on private and federal land use, how to better promote species recovery, agency use of scientific information, specific regional resource conflicts, and other matters. Below are descriptions of some of the issues that were most commonly raised.

		Critical Habitat Designation

With limited exceptions, FWS or NMFS must designate CH at the time a species is listed. However, some critics argue that CH designation places undue burdens on landowners or that it has little conservation benefit. Others argue (and the courts have largely agreed) that FWS and NMFS have misinterpreted and failed to enforce the current statute. There are also disagreements over the value and timing of CH designation. (See " Critical Habitat ," above, and " ESA Listing Caps, New and Old ," below.)
In the 109 th Congress, §5 of H.R. 3824 would have repealed the designation of CH and labeled current areas of CH as areas of special value for recovery planning purposes. The House Committee on Resources reported this bill (amended) on September 27, 2005 ( H.Rept. 109-237 ), and the House passed it (amended) on September 29, 2005. H.R. 1299 would have modified the CH definition as well as the process for determining and designating CH. H.R. 1837 would have limited CH designation for some aquatic habitats. S. 2110 would have designated any habitat of an endangered species or a threatened species that is considered to be CH in accordance with the priority system.

		"Sound Science" and the ESA

The ESA requires that determinations of species status be made "solely on the basis of the best scientific and commercial data available ..." In several recent situations, legal, economic, and social disputes have resulted from actions under the ESA. Examples of these controversies include the Canada lynx, Florida panthers, and Klamath River Basin suckers and coho salmon. Critics in some of these disputes suggest that the science supporting ESA action has been insufficiently rigorous or mishandled by the agencies.
Many rare and endangered species are little studied because they are hard to find or because it is difficult to locate enough of them to support scientific research. There may be little information on many species facing extinction, and only limited personnel or funds available to conduct studies on many of the less charismatic species, or those of little known economic import. What should be done in such instances? Some suggest that considerations other than species conservation should prevail; others seek to change the current posture of the law by changing the role of science. These considerations are complicated by the costs and time required to acquire more complete data, particularly in connection with many lesser-known species.
The ESA does not elaborate on this question, but some assert that, given the protective purpose of the ESA—to save and recover species—and the wording of "best ... data available ," arguably dwindling species are to be given the benefit of the doubt and a margin of safety provided. This is the position taken on page 1-7 of the Endangered Species Consultation Handbook , which states that efforts should be made to develop information, but if a biological opinion must be rendered promptly, it should be based on the available information, "giving the benefit of the doubt to the species," with consultation possibly being reinitiated if additional information becomes available. This phrase is drawn from H.Rept. 96-697, p. 12 (1979), which states that the "best information available" language was intended to allow FWS to issue biological opinions even when information was incomplete, rather than being forced to issue negative opinions. The report also states that if a biological opinion is rendered on the basis of inadequate information, the federal agency proposing an action has the duty to show its actions will not jeopardize a species and a continuing obligation to make a reasonable effort to develop information, and that the statutory language "continues to give the benefit of the doubt to the species."

			Information Quality

Section 515 of P.L. 106-554 , known as the Information Quality Act or the Data Quality Act, directs the Office of Management and Budget (OMB) to issue government-wide guidelines to federal agencies to ensure and maximize the quality, objectivity, utility, and integrity of information disseminated by federal agencies. OMB published final guidelines on February 22, 2002. The Department of the Interior and FWS have both issued additional guidelines that are available through their websites, and a process is established for interested persons to seek correction of information. Even before these latest guidelines, FWS had promulgated guidance on information quality and peer review procedures—issues that also have been addressed in recent legislation.
FWS and NMFS developed an Interagency Cooperative Policy on Information Standards Under the Endangered Species Act. Under this policy, FWS and NMFS are to receive and use information from a wide variety of sources, including from individuals. Submitted information may range from the informal—oral, traditional, or anecdotal—to peer-reviewed scientific studies, and hence the reliability of the information can vary widely. Agency biologists are to review and evaluate all information impartially for purposes of listing, CH designation, consultation, recovery, and permitting actions, and to ensure that any information used by the agencies to implement the ESA is "reliable, credible, and represents the best scientific and commercial data available." Agency biologists are to document their evaluations of all information and, to the extent consistent with the use of the best scientific and commercial data available, use primary and original sources of information as the basis for recommendations. In addition, agency managers are to review the work of FWS and NMFS biologists to "verify and assure the quality of the science used to establish official positions, decisions, and actions..."
Additionally, a companion document, the Interagency Cooperative Policy for Peer Review in Endangered Species Act Activities, notes that, in addition to the public comments received on proposed listing rules and draft recovery plans, the Services are also to formally solicit expert opinions and peer review to ensure the best biological and commercial information. For listing decisions, the agencies are to solicit the expert opinions of three specialists and summarize these in the record of final decision. Special independent peer review can also be used when it is likely to reduce or resolve an unacceptable level of scientific uncertainty.

			Court Cases on the ESA and Science29

Courts that have considered the "best data available" language have held that an agency is not obliged to conduct studies to obtain missing data, but cannot ignore available biological information, especially if the ignored information is the most current. Nor may an agency treat one species differently from other similarly situated species, nor decline to list a dwindling species and wait until it is on the brink of extinction in reliance on possible but uncertain future actions of an agency. "Best scientific and commercial data available" is not a standard of absolute certainty, reflecting Congress's intent that FWS take conservation measures before a species is conclusively headed for extinction. If FWS does not base its listings on speculation or surmise or disregard superior data, the imperfections of the studies upon which it relies do not undermine those studies as the best scientific data available—"the Service must utilize the best scientific ... data available , not the best scientific data possible ."
Judicial review can also help ensure that agency decisions and their use of scientific data are not "arbitrary or capricious" and that regulations are rationally related to the problems causing the decline of a species, especially when other interests are adversely affected. In Arizona Cattle Growers Association v. United States Fish and Wildlife Service , the court stated that the evidentiary bar FWS must clear is very low, but it must at least clear it. In the context of issuing Incidental Take Permits under §10(a), this ruling means the agency must demonstrate that a species is or could be in an area before regulating it, and must establish the causal connection between the land use being regulated and harm to the species in question. Mere speculation as to the potential for harm is not sufficient. An agency must consider the relevant facts and articulate a rational connection between these facts and the choices made.

		Regional Resource Conflicts

One express purpose of the ESA is to "provide a means whereby the ecosystems upon which endangered species and threatened species depend may be conserved" (16 U.S.C. §1531(b)). As open space dwindles and increasing human populations put pressures on our wildlands and natural resources, the conservation of species and their habitats may highlight underlying resource crises and economic conflicts. Public values and affected economic interests may be complex and sometimes at odds. The situations described below are some of the situations that have been the subject of recent congressional oversight and legislative interest. In the 109 th Congress and reflecting several of these regional conflicts, the House Resources Subcommittee on Water and Power held an oversight hearing on June 22, 2005, focusing on the effect of the ESA on water supplies.

			Klamath River Basin

Controversy erupted in 2001 when the Department of the Interior's Bureau of Reclamation announced it would not release water from part of its Klamath irrigation project to approximately 200,000 acres of farm and pasture lands within the roughly 235,000-acre project service area. The operational change sought to make more water available for three fish species under ESA protection—two endangered sucker species, and a threatened coho salmon population. The Klamath Project straddles the Oregon/California border and has been the site of increasingly complex water management issues involving several tribes, fishermen, farmers, environmentalists, and recreationists. Upstream farmers point to their contractual rights to water from the Klamath Project and to hardships for their families if water is cut off. Others assert that the downstream salmon fishery is more valuable and that farmers could be provided temporary economic assistance, while salmon extinction would be permanent. Still others assert that there are ways to serve all interests, or that the science underlying agency determinations is simply wrong. Specifically at issue is how to operate the Bureau's project facilities to meet irrigation contract obligations without jeopardizing the three listed fish. The Trinity River diversion from the Klamath basin to central California also has ramifications for the Bureau's role in the Central Valley Project. Various 10-year and annual operation plans, and associated biological assessments (by the Bureau) and biological opinions (by FWS and NMFS) have been criticized and defended.

			Pacific Salmon Restoration

Salmon protection in the Pacific Northwest in general presents many difficult choices, especially because of recent droughts and the connection between regional hydropower facilities and fishery management decisions. NMFS officials have listed a total of 26 distinct population segments (called evolutionarily significant units or ESUs) of Pacific salmon and steelhead trout as either threatened or endangered, and are working with state, local, and tribal officials, as well as the public, to implement recovery measures addressing habitat restoration and other concerns. Recent controversies and litigation have focused on three issues: (1) biological opinions on operation of the Federal Columbia River Power System (FCRPS) as it relates to retaining (or removing) four dams on the lower Snake River, and how properly to factor the presence of the dams into evaluations of jeopardy; (2) whether or not salmon produced in hatcheries should be included in listed ESUs of Pacific salmon; and (3) the role and extent of CH designation in the recovery of Pacific salmon. Interim decisions of the federal district court for Oregon have invalidated NMFS's approach to evaluating jeopardy to salmon from dam operations on the Columbia and Snake Rivers, and ordered increased spills of water to assist transit of juvenile salmon to the sea.
In the 109 th Congress, S. 232 would have authorized the Bureau of Reclamation to assist in implementing fish passage and screening facilities at nonfederal water projects in the Columbia River Basin to meet the Bureau's ESA obligations. On March 10, 2005, the Senate Committee on Energy and Natural Resources reported S. 232 ( S.Rept. 109-31 ); the Senate passed it on July 26, 2005. H.R. 1615 would have required a National Academy of Sciences analysis of federal salmon recovery efforts and a Government Accountability Office study of the effects of partially removing four lower Snake River dams, and would have authorized partial removal of these four dams under certain conditions. Section 103 of S. 2432 / H.R. 5006 would have designated salmon restoration areas in California. H.R. 6377 and S. 4084 would have authorized implementing the San Joaquin River Restoration Settlement providing for the reintroduction of spring-run chinook salmon below Friant Dam.

			Rio Grande Silvery Minnow

Efforts to hold back water necessary for the Rio Grande silvery minnow from competing New Mexico water users (primarily the city of Albuquerque and irrigators) ignited considerable controversy. At issue is the operation of two Bureau of Reclamation water projects on the Middle Rio Grande: the San Juan-Chama Project and the Middle Rio Grande Project. The New Mexico District Court held that withholding water from irrigators for ESA-related purposes was permissible under the water contracts at issue. Congress halted implementation and an agreement regarding the minnow has been negotiated.
In the 109 th Congress, §121 (Title I, Corps of Engineers) of P.L. 109-103 authorized certain activities related to the Middle Rio Grande Endangered Species Collaborative Program (MRGESCP). S. 1540 would have directed the Secretary of the Army and the Secretary of the Interior to establish the MRGESCP to improve water management and contribute to the recovery of endangered species in the Middle Rio Grande, NM. S. 2254 would have directed the Corps of Engineers to carry out restoration projects along the Middle Rio Grande in consultation with the MRGESCP.

		Counterpart Regulations: Pesticides and Fire Management Projects

In 50 C.F.R. §402.04, "counterpart" regulations are authorized that allow an action agency to determine unilaterally whether its actions are likely to adversely affect listed species, thereby avoiding §7 consultation with FWS or NMFS. Although the regulation has been on the books for years, it has not been used until recently, and hence its validity has not yet been tested in the courts. Several new counterpart regulations have recently been finalized and suits challenging the regulations have been filed.
New counterpart pesticide regulations were finalized on August 5, 2004, for Environmental Protection Agency (EPA) regulatory actions on pesticides, such that when the EPA is taking action under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA; P.L. 80-104; 7 U.S.C. §§136, et seq.), the EPA and FWS may execute an alternative consultation agreement under which the EPA will decide whether a proposed FIFRA action is likely to adversely affect a listed species or critical habitat. The EPA may make this determination without informal consultation with, and written concurrence from, the FWS Director. If the EPA makes such a determination, no further consultation is required. There is to be FWS oversight of the consistency of EPA's determinations with the ESA. Under 50 C.F.R. §402.43, the EPA may ask FWS for information on listed species that may be present in an area that might be affected by the FIFRA action, including the applicable environmental baseline for each species or habitat, and under new §402.44, the EPA may request FWS personnel to assist in an effects determination and must use its "best efforts" to include the FWS representative in relevant discussions. These two regulations appear to apply with or without an alternative consultation agreement. Critics note that the EPA has a poor record on consultations, and fear that the new self-consultation process will allow more harm to listed species. Supporters counter that the new process will increase EPA flexibility and efficiency.
On August 24, 2006, U.S. District Court Judge John Coughenour overturned EPA counterpart regulations relating to pesticides, ruling that these regulations did not conform to the plain language or intent of the ESA §7 by excusing federal action agencies from engaging in consultation with FWS or NMFS. In addition, he held that it was illegal for FWS or NMFS to allow EPA to use emergency consultation procedures for FIFRA §18 actions. Judge Coughenour let stand the process of "optional formal consultation" in which NMFS or FWS can adopt EPA effects determinations as their own.
Counterpart regulations also were finalized December 8, 2003, among the Forest Service, the Bureau of Land Management, the Bureau of Indian Affairs, the National Park Service, FWS, and NMFS, to streamline consultation on projects supporting the National Fire Plan (NFP). The alternative consultation process contained in these counterpart regulations eliminates the need to conduct informal consultation with FWS or NMFS, and eliminates the requirement to obtain written concurrence from FWS or NMFS for those NFP actions that the action agency determines are "not likely to adversely affect" any listed species or designated CH.

		Private Property and Fifth Amendment Takings

The presence of endangered species on private property is sometimes welcomed by owners. Builders, for example, have been known to market a new residential development in part on the basis of the wildlife present on undeveloped parts of the tract. Still, the prohibitions in §9 (private actions) and §7 (federal nexus) may at times frustrate the economic desires of owners of land or other property. This has long been a rallying cry for the ESA's detractors, who assert that restrictions under the ESA routinely "take" property in the constitutional sense of the term. Conflicts between the ESA and property owners come about despite the existence of ESA mechanisms intended to soften its impact on property owners.
Under the Fifth Amendment, property cannot be "taken" by the United States without just compensation. The Supreme Court has long tried, with limited success, to define which government actions affect private property so severely as to effect such a "taking." In briefest outline, government actions usually are deemed a taking when they cause either a permanent physical occupation of private property or a total elimination of its economic use. When the government restriction removes only part, but not all, of the property's use or value, a three-factor balancing test is used. Although these factors have been little explicated by the courts, it is clear that for a taking to occur, the property impact must be severe. Moreover, except for physical takings, the property impact is assessed with regard to the property as a whole, not just the regulated portion.
More than a dozen court decisions have addressed takings challenges to ESA restrictions on land or other property, with all but one finding no taking. These cases have involved restrictions on timber cutting, reductions in water delivery to preserve instream flows needed by listed species, restrictions on shooting marauding animals resulting in loss of livestock, and prohibitions on the transport or sale of endangered species. In several of these cases, the taking claim failed because it was filed in the wrong court or was not "ripe." Where taking claims were reached by the court, they were rejected principally because the economic impact was insufficient as to the property as a whole, or because of the longstanding principle that the government is not responsible for the actions of wild animals. In the one decision favoring the property owner, ESA-related cutbacks in water delivered by a state reclamation project to water districts were held a taking by the United States of state-contract-created water rights. This decision has been controversial for several reasons, including the Department of Justice's settlement of the case (for $16.7 million) despite arguments pressed on it from several quarters that the case was incorrectly decided.
ESA critics want the ESA amended to afford compensation for a broader range of property impacts than the Constitution provides—perhaps by specifying a fixed percentage of ESA-related property value loss, above which compensation must always be paid. Similar provisions have been included in bills of previous Congresses. In the 109 th Congress, §14 of H.R. 3824 would have required federal compensation for property owners who forgo use of property following determinations that continued use would not comply with prohibitions on taking ESA-listed species. The House Committee on Resources reported this bill (amended) on September 27, 2005 ( H.Rept. 109-237 ), and the House passed it (amended) on September 29, 2005. Opponents of an explicit compensation standard counter that the ESA should not be singled out for a more property owner-friendly standard than other statutes' or the Constitution's. More fundamentally, they note that property rights have never been absolute, and that regulation has long been noncompensable as long as the impact on the property owner is not severe. The likely consequences of a generous compensation threshold—added federal costs and/or a chill on ESA implementation—are among the issues slowing action on ESA reauthorization. However, both proponents and opponents of the ESA favor enacting incentives (primarily tax benefits) to encourage landowner cooperation.
Also in the 109 th Congress, §3 of H.R. 411 would have awarded compensation for ESA activities that eliminate or reduce grazing privileges. H.R. 3166 would have authorized the waiver of grazing permits in designated CH and provide compensation for waived permits. S. 2110 would have provided a variety of tax benefits. S. 4087 would have provided a tax credit to individuals who entered into agreements to protect endangered and threatened species habitat.

		Making the ESA More User-Friendly

Former Interior Secretary Babbitt initiated actions to decrease ESA conflicts in several ways. Joint FWS and NMFS policies streamlined permit procedures for small landowners, and other initiatives encouraged landowners to increase protection for populations of listed species on their land. Under safe harbor agreements, landowners who increased suitable habitat could return to "baseline conditions" without penalty. No surprises agreements provided landowners with greater certainty regarding activities that might otherwise trigger penalties—an incentive for landowners to develop Habitat Conservation Plans (HCP), since a landowner properly implementing such an agreement is assured that there will be no further costs or restrictions on the use of the property to benefit the species covered by the HCP, except by mutual consent or in unforeseen circumstances in which changes may be implemented by the government without costs borne by the landowner. Modifications to the no surprises rule required revoking an incidental take permit if the permitted taking would be inconsistent with the survival and recovery of the relevant listed species, and the inconsistency was not remedied in a timely fashion. These rules were reproposed and finalized in response to litigation, but may still present issues raised previously. Federal managers also focused on listing species as threatened rather than endangered, to allow FWS to take advantage of the ESA's more flexible provisions for protecting threatened species. While administrative changes have been made within the framework of existing law, there is great interest among some groups in codifying many of these changes in an amended ESA. Others are critical of HCP agreements as difficult to enforce, virtually lacking monitoring, and locking the government into inflexible long-term positions that sometimes are based on inadequate knowledge.
In the 109 th Congress, §365 of P.L. 109-58 , the Energy Policy Act of 2005, established a pilot project in WY, MT, CO, UT, and NM to better coordinate certain actions among federal agencies, including consultations and the preparation of biological opinions under ESA §7. In addition, P.L. 109-294 ( S. 260 ) expanded the authority of the Secretary of the Interior to assist private landowners in restoring, enhancing, and managing endangered and threatened species habitat on private land through the Partners for Fish and Wildlife Program. A number of additional bills were introduced in the 109 th Congress:
H.R. 3300 would have authorized species recovery agreements obligating the federal government to make annual payments or provide other compensation for activities that improve the recovery of listed species; S. 1497 would have required the Secretary of the Interior to provide incidental take permits to public electric utilities that adopt measures to mitigate hazards to eagles and other migratory birds; S. 2110 would have codified the no surprises policy; and Section 106(b) of H.R. 6064 and §205(c) of H.R. 6193 would have authorized the Secretary of Agriculture to provide incentive payments to landowners through the Wildlife Habitat Incentive Program to protect or restore the habitat of federally or state-listed endangered, threatened, and candidate species.

		Additional Legislative Initiatives

In the 109 th Congress, bills were introduced in both the House and Senate to reauthorize and amend the ESA. The House Committee on Resources reported H.R. 3824 (the Threatened and Endangered Species Recovery Act of 2005, amended) on September 27, 2005 ( H.Rept. 109-237 ); the House passed H.R. 3824 (amended) on September 29, 2005. S. 2110 , the Collaboration for the Recovery of Endangered Species Act, was introduced on December 15, 2005.
Proponents of both bills said that they were designed to make the ESA more effective by redefining the relationship between private and public property uses and species protection, implementing new incentives for species conservation, and removing what some see as undue land use restrictions. Thus, both proposals contained provisions meant to encourage greater voluntary conservation of species by states and private landowners, a concept that has been supported by many observers. Further, both proposals would have modified or eliminated certain procedural or other elements of the current ESA that some have viewed as significant protections and prohibitions, including:
eliminating or changing the role of "critical habitat" (CH) (which would eliminate one aspect of the current consultation process); making the listing of all threatened and endangered species more difficult or less likely; expanding §10 permits allowing incidental take (which could incur a greater need for agency oversight and enforcement); and expanding state rather than federal implementation of ESA programs (which might make oversight more difficult).
Proponents of these changes argued that tighter listing standards would enable a better focus on species with the most dire needs, and that other measures would achieve recovery of more species. Critics argued that proposed changes would create gaps in the ESA safety net of protections and prohibitions.
P.L. 109-183 ( S. 1578 ) reauthorized Upper Colorado and San Juan River Basin endangered fish recovery programs. P.L. 109-225 ( S. 1165 ) expanded Hawaii's James Campbell National Wildlife Refuge to protect habitat for endangered waterbirds. P.L. 109-449 established NOAA and Coast Guard programs to manage marine debris and address its adverse effects on endangered species. Additional measures were considered by the 109 th Congress:
Section 212 of S. 2012 and §209 of H.R. 5051 would have required a study of sea turtle excluder devices in shrimp trawls; S. 2012 was reported by the Senate Committee on Commerce, Science, and Transportation on April 4, 2006 ( S.Rept. 109-229 ), and was passed by the Senate (amended) on June 19, 2006. On December 7, 2006, the Senate passed H.R. 5946 , after amending this measure to substitute language from amended S. 2012 . The House passed the amended H.R. 5946 on December 9, 2006, with the turtle excluder language in §212. S. 2013 and §17 of H.R. 4075 , as passed by the House on July 17, 2006, would have implemented the Agreement on the Conservation and Management of the Alaska-Chukotka Polar Bear Population. The Senate Committee on Commerce, Science, and Transportation reported S. 2013 on February 27, 2006 ( S.Rept. 109-217 ); the Senate passed this measure (amended) on June 6, 2006. On December 6, 2006, the Senate amended H.R. 4075 to insert the language of S. 2013 and passed the amended H.R. 4075 . On December 7, 2006, the Senate amended H.R. 5946 to insert the language of S. 2013 as Title IX, and passed the amended H.R. 5946 . On December 9, 2006, the House agreed to the amended H.R. 5946 . Section 1505 of S. 732 , as reported on April 6, 2005 ( S.Rept. 109-53 ), by the Senate Committee on Environment and Public Works, would have authorized state programs for mitigating highway and surface transportation impacts, including those affecting endangered and threatened species. H.R. 4857 would have required that certain electricity consumers be informed of ESA compliance costs; the House Committee on Resources held a hearing on this bill on March 16, 2006, and reported the bill on September 28, 2006 ( H.Rept. 109-693 ). H.R. 3110 would have amended the ESA to treat distinct population segments of the Eastern oyster as separate species. On July 19, 2005, the House Committee on Resources held an oversight hearing on ESA listing of this species. S. 164 would have facilitated acquisition of UT lands to protect desert tortoise. H.R. 2323 would have promoted southern sea otter recovery and research. H.Res. 249 celebrated the rediscovery of the ivory-billed woodpecker in Arkansas. H.R. 2779 would have amended the ESA to enable federal agencies to rescue and relocate threatened or endangered species in certain circumstances where flood control levees are reconstructed, maintained, or repaired. S.Res. 219 would have designated March 8, 2006, as "Endangered Species Day." S.Res. 431 designated May 11, 2006, as "Endangered Species Day"; the Senate agreed to S.Res. 431 on April 5, 2006. Section 203 of H.R. 3908 would have amended the Internal Revenue Code to exempt payments from gross revenue for landowner incentive programs that conserve species or protect habitat. S. 3611 would have authorized the Secretary of the Interior to implement the Platte River Recovery Implementation Program for Endangered Species in the Central and Lower Platte River Basin. Section 209 of H.R. 6193 would have directed the Secretary of Agriculture to establish a pilot program to recover California endangered or threatened plant species. H.R. 6241 would have amended the Marine Mammal Protection Act to authorize the taking of California sea lions to protect endangered and threatened salmon species in the Columbia River drainage.
Section 1505(c) of H.R. 3 , as agreed to by the Senate on May 17, 2005, would have provided for state mitigation funds to benefit endangered and threatened species; however, these provisions were not retained in the conference agreement, subsequently enacted as P.L. 109-59 .

		Appropriations

Appropriations play an important role in the ESA debate, providing funds for listing and recovery activities as well as financing FWS and NMFS consultations that are necessary for federal projects. In addition, appropriations bills have served as vehicles for some changes in the ESA.
 Table 2 shows recent ESA funding. The FY2006 Department of the Interior, Environment, and Related Agencies Appropriations Act, P.L. 109-54 , provided $271.9 million for FWS's ESA activities. Overall, FY2006 FWS funding for ESA and related programs is $6.5 million less than the President's request, and $11.8 million more than the FY2005 appropriations level. FY2006 funding for ESA programs administered by NMFS was provided in the Science, State, Justice, Commerce, and Related Agencies Appropriations Act, P.L. 109-108 . Provisions in P.L. 109-148 ( H.R. 2863 , the Department of Defense, Emergency Supplemental Appropriations to Address Hurricanes in the Gulf of Mexico, and Pandemic Influenza Act) rescinded unobligated balances of $2 million from FWS's Landowner Incentive Program and $1 million from the Cooperative Endangered Species Conservation Fund. For FY2007, FWS appropriations are provided in H.R. 5386 , which passed the House (amended) on May 18, 2006; the Senate Committee on Appropriations reported this bill (amended) on June 29, 2006 ( S.Rept. 109-275 ). The 109 th Congress did not complete action on FY2007 appropriations for either FWS or NMFS.
An April 2005 GAO study found that, although FWS spends almost half of its recovery funds on highest priority species, factors other than a species' priority ranking (e.g., regional office workload, opportunities for partnerships to maximize scarce recovery funds), in practice, determine how funding is allocated. GAO found that FWS does not have a process to routinely assess funding decisions to ensure that they are appropriate.

			ESA Listing Caps, New and Old

Beginning in FY1998, Congress enacted annual limits ( caps ) on funding FWS could use for its ESA listing function. This appropriations language limits FWS discretion to transfer funds to finance additional listings, so that if courts mandate agency action on listing certain species, other listings may not be able to be funded. FWS supported these limits to assure that funding for other agency programs could not be diverted to finance additional ESA listing activities. However, courts have held that budget constraints do not excuse an agency from compliance, in some circumstances. These limits have been approved by Congress in succeeding fiscal year appropriations bills. P.L. 109-54 , FY2006 Department of the Interior appropriations, limits listing activities to $18.13 million, of which no more than $12.852 million could be used for activities related to critical habitat designation. For FY2007, the Bush Administration proposed limiting listing activities to $17.759 million, of which no more than $12.581 million could be used for activities related to critical habitat designation; the House agreed with the Administration's request, while the Senate Committee on Appropriations has reported limiting listing activities to $17.859 million, of which no more than $12.672 million could be used for critical habitat designation.

Summary:
The 109th Congress considered numerous proposals to amend the Endangered Species Act (ESA; P.L. 93-205, 16 U.S.C. §§1531-1543). Major issues in recent years have included changing the role of science in decision-making, modifying critical habitat (CH) procedures, incorporating further protection and incentives for property owners, and increasing protection of listed species, among others. In addition, many have advocated enacting as law some ESA regulations promulgated during the Clinton Administration.
The ESA has been one of the more contentious environmental laws. This may stem from its strict substantive provisions, which can affect the use of both federal and nonfederal lands and resources. Under the ESA, species of plants and animals (both vertebrate and invertebrate) can be listed as endangered or threatened according to assessments of their risk of extinction. Once a species is listed, powerful legal tools are available to aid its recovery and protect its habitat. The ESA may also be controversial because dwindling species are usually harbingers of broader ecosystem decline: the most common cause of listing species is habitat loss.
The authorization for spending under the ESA expired on October 1, 1992. The prohibitions and requirements of the ESA remain in force, even in the absence of an authorization, and funds have been appropriated to implement the administrative provisions of the ESA in each subsequent fiscal year. In the 109th Congress, H.R. 3824 and S. 2110 proposed to extensively amend and reauthorize the ESA; the House passed H.R. 3824 (amended) on September 29, 2005. Proponents of both bills argued that they were designed to make the ESA more effective by redefining the relationship between private and public property uses and species protection, implementing new incentives for species conservation, and removing what some see as undue land use restrictions. However, critics argued that proposed changes created gaps in the ESA safety net of protections and prohibitions.
The 109th Congress enacted legislation that (1) established a pilot project in Wyoming, Montana, Colorado, Utah, and New Mexico to better coordinate consultations and the preparation of biological opinions under ESA §7 (P.L. 109-58); (2) authorized certain activities related to the Middle Rio Grande Endangered Species Collaborative Program (P.L. 109-103); (3) reauthorized Upper Colorado and San Juan River Basin endangered fish recovery programs (P.L. 109-183); (4) expanded a Hawaiian National Wildlife Refuge to protect habitat for endangered waterbirds (P.L. 109-225); (5) expanded the authority of the Secretary of the Interior to assist private landowners in restoring, enhancing, and managing endangered and threatened species habitat on private land through the Partners for Fish and Wildlife Program (P.L. 109-294); (6) reauthorized and amended the Neotropical Migratory Bird Conservation Act and the Great Ape Conservation Act of 2000 (P.L. 109-363); and (7) established programs to manage marine debris and address its adverse effects on endangered species (P.L. 109-449). This report also identifies additional bills that were introduced in the 109th Congress to address specific concerns related to how the ESA is implemented and how endangered species are managed.
