The annual Interior, Environment, and Related Agencies appropriations bill funds agencies and programs in three federal departments, as well as numerous related agencies and bureaus. Among the more controversial agencies represented in the bill is the Fish and Wildlife Service (FWS), in the Department of the Interior (DOI). This report analyzes FY2011 appropriations and gives a brief review of the agency's appropriation enacted for FY2010 ( P.L. 111-88 ). For FWS in FY2011, the Administration requests $1.64 billion, down 0.3% from the FY2010 level of $1.65 billion. By far the largest portion of the FWS annual appropriation is the Resource Management account, for which the President requests $1.27 billion, down 0.07% from the FY2010 level of $1.27 billion. Among the programs included in Resource Management are Endangered Species, the Refuge System, Law Enforcement, and Climate Change Adaptive Science Capacity. Only a few FWS issues that may arise in an appropriations context seem predictable at this early phase of the appropriations cycle. One possibility may be the management of certain California water projects. The Bureau of Reclamation has faced many legal challenges in its role as a water resources manager in California. Among them are lawsuits challenging how Reclamation operations may affect several species listed under the Endangered Species Act (ESA). Over a year ago both FWS and the National Marine Fisheries Service (NMFS) issued separate biological opinions (BiOps) for Central Valley Project (California) water operations, holding that certain actions by Reclamation would jeopardize listed species. Under the ESA, these BiOps provided alternatives to avoid jeopardy or adverse modification of habitat designated as critical to the listed species. In addition, the BiOps provided incidental take statements (ITSs) that authorized takes of listed species that might result even though the action agency followed the BiOp, the alternatives, and any mitigation recommended by FWS or NMFS. Some of the actions in the alternatives may result in restricting water supplies to certain water users in central and southern California. The agricultural users are in regions of California that are also heavily affected by the general downturn in the economy and loss of jobs in the building construction industry. Various California water interests support restricting or modifying the implementation of the BiOps to provide more water for agriculture. Others in the area point to the need for maintaining water in streams not only for listed species but also for commercial fisheries and water quality. While the shape of the congressional response is unclear, FWS appropriations might become a vehicle for an amendment to address California long-standing water issues. Funding for the endangered species program is part of the Resource Management account, and is one of the perennially controversial portions of the FWS budget. The Administration's FY2011 request is $181.3 million, an increase from the FY2010 enacted level of $179.5 million. (See Table 2 .) For FY2010, the House Appropriations Committee's report encouraged FWS to address a backlog of candidate species awaiting listing decisions; the Administration's request proposed a decrease in this program for FY2011. The Senate Appropriations Committee's FY2010 report urged improvement in the consultation program to address past deficiencies. The FY2010 conference report set aside $2.5 million in the consultation program to improve monitoring and record-keeping. The Cooperative Endangered Species Conservation Fund also benefits conservation of species that are listed, or proposed for listing, under the Endangered Species Act, through grants to states and territories. The President proposes to leave the program at the FY2010 level. In total, the two endangered species programs would increase by 1%. The Administration requested $499.5 million for FY2011 for refuge operations and maintenance, a 1% decrease from the FY2010 level of $502.8 million. Costs of operations have increased on many refuges, partly due to special problems such as hurricane damage and more aggressive border enforcement, but also due to increased use, invasive species control, maintenance backlog and other demands. Refuge funding was not keeping pace with new demands, and these demands, combined with the rising costs of rent, salaries, fuel, and utilities, led to cuts in funding for programs to aid endangered species, reduce infestation by invasive species, protect water supplies, address habitat restoration, and ensure staffing at the less popular refuges. While some increases were provided to address these problems in recent years, the FY2009 stimulus law provided additional funding to address these concerns. Some observers contend that the system's problems are ongoing and will be significant after the stimulus funding is exhausted. Balanced against these concerns is congressional interest in general deficit reduction. The Administration requests $63.3 million for nationwide law enforcement, a decrease of 4% from the FY2010 level of $65.8 million. Nationwide law enforcement covers border inspections, investigations of violations of endangered species or waterfowl hunting laws, and other activities. The American Recovery and Reinvestment Act of 2009 (ARRA, P.L. 111-5 ) provided FWS with $165.0 million for Resource Management and $115.0 million for Construction, using nearly identical criteria for project selection. Obligation authority for these funds ceases on October 1, 2010. According to FWS, "[t]o complete this work, we plan to hire local laborers, building contractors, companies and other entities to do the maintenance, repairs, retrofits, and construction." Refuges are among the biggest beneficiaries within FWS of the stimulus funding, and the refuge maintenance backlog could be affected substantially. Improvements in energy conservation at refuge visitor centers are also being funded, as are habitat improvements, such as removal of invasive species, and recovery of protected species. For FY2011, the Administration requests $28.8 million for Climate Change Planning and Adaptive Science Capacity, an increase of 44% over the FY2010 level of $20.0 million. Part of the funding would support work with partners at federal, state, tribal, and local levels to develop strategies to address climate impacts on wildlife at local and regional scales. The remainder would be used to support cooperative scientific research on climate change as it relates to wildlife impacts and habitat. Both portions would support and work through a network of new Landscape Conservation Cooperatives (LCCs) to ameliorate the effects of climate change. The LCCs are an amalgam of research institutions, federal resource managers and scientists, and lands managed by agencies at various levels of government. The additional funding is intended to increase the network of LCCs from 9 to 12, with an eventual goal of 21 LCCs. The Administration requests $106.3 million for land acquisition, an increase of $20.0 million (19%) from the FY2010 enacted level of $86.3 million. See Table 1 . As compared to recent years, the request and the FY2010 level both devote a somewhat higher percentage (80% and 77% respectively) of the funding to acquisition of land for specified federal refuges, rather than for closely related functions (e.g., acquisition management, land exchanges, emergency acquisitions, and purchase of inholdings). This program is funded with appropriations from the Land and Water Conservation Fund. Under the Migratory Bird Conservation Account (MBCA), FWS (in contrast to the other three federal lands agencies) has a source of mandatory spending for land acquisition. The MBCA does not receive funding in annual Interior appropriations bills. The account is permanently appropriated, with funds for FY2011 estimated at $58.0 million, derived from the sale of duck stamps to hunters and recreationists, and import duties on certain arms and ammunition. This estimate is $14.0 million above the previous year, and is based in part on the assumption that Congress approves a proposed increase in the price of duck stamps from $15 to $25. The National Wildlife Refuge Fund (also called the Refuge Revenue Sharing Fund) compensates counties for the presence of the non-taxable federal lands of the NWRS. A portion of the fund is supported by the permanent appropriation of receipts from various activities carried out on the NWRS. However, these receipts are not sufficient for full funding of amounts authorized in the formula, and county governments have long urged additional appropriations to make up the difference. For FY2011, the Administration requests $14.1 million, down 3% from the FY2010 level of $14.5 million. With refuge receipts, the FY2010 appropriation was estimated to fund about 36% of the authorized payment level. A projected increase in receipts, combined with the appropriation of $14.1 million, would increase the payment to 38% of the authorized level in FY2010. The Multinational Species Conservation Fund generates considerable constituent interest despite the small size of the program. It benefits Asian and African elephants, tigers, rhinoceroses, great apes, and marine turtles. The President requests $10.0 million for FY2011, a 13% decrease from the FY2010 level of $11.5 million. See Table 3 . The President also requests $4.0 million for the Neotropical Migratory Bird Conservation Fund, down 20% from the FY2010 level of $5.0 million. State and Tribal Wildlife Grants help fund efforts to conserve species (including nongame species) of concern to states, territories, and tribes. The grants have generated considerable support from these governments. The program was created in the FY2001 Interior appropriations law ( P.L. 106-291 ) and further detailed in subsequent Interior appropriations laws. (It has no separate authorizing statute.) Funds may be used to develop state conservation plans as well as to support specific practical conservation projects. A portion of the funding is set aside for competitive grants to tribal governments or tribal wildlife agencies. The remaining portion is for grants to states.
