animal diseases – Invasive Species

What the new President & Congress Can Do re: Invasive Species
A new President and Congress take office in January. And outgoing President Obama recently amended the Executive Order on invasive species.
What might the new leaders do to improve America’s invasive species programs?
Here are a group of actions that I think would improve programs significantly:
amend the Lacey Act to strengthen controls over introduction and spread of invasive animals and animal diseases;
raise the political profile of invasive species issues by holding more frequent oversight hearings;
increase funding for invasive species prevention, containment, and control programs;
support proposals to amend the 2019 Farm Bill to strengthen on-the-ground programs, policies, and research aimed at minimizing invasive species introduction, spread, and damage;
during the confirmation process, Senators should ask President Trump’s nominees to leadership positions in the Departments of Agriculture and Interior about how they will address invasive species challenges.
Do we need new legislation mandating that federal land-managing agencies do X or Y with regard to invasive species? This was the focus of a hearing in May at which I testified.
Federal land-managing agencies are already authorized and – in some cases required – to act to control invasive species on lands and waters under their jurisdiction. Some of the existing statutes even authorize the agencies to apply fees paid by people who use the public lands for some purpose (e.g., livestock grazing, recreation) to management of invasive species.
Most of the statutes authorizing invasive species management incorporate that activity into the agency’s broader management goals for protection of wildlife, habitat, natural resources, historic or cultural sites, etc. For example, the USFS Manual §2900 lists 21 laws and 6 regulations or policies that govern the USFS’ management of invasive species. Some of these laws apply to all federal land-managing agencies, including:
Endangered Species Act (ESA) of 1973 (16 U.S.C. §§1531 et seq.)
Surface Mining Control and Reclamation Act of 1977 (30 U.S.C. 1201, 1201 (note), 1236, 1272, 1305). §515
North American Wetland Conservation Act 1989 (16 U.S.C. 4401 (note), 4401-4413, 16 U.S.C. 669b (note)). §9 [U.S.C. 4408]
Sikes Act (Fish and Wildlife Conservation) of September 15, 1960 (16 U.S.C. 670g-670l, 670o, P.L. 86-797), as amended. §201
National Historic Preservation Act of 1966 [16 U.S.C. §§470 et seq.]
Wilderness Act of 1964 (16 U.S.C. §§1131 et seq.
Other statutes apply only to resource management authorities of the USDA Forest Service; these include:
Organic Administration Act of 1897 (16 U.S.C. §§ 473 et seq.).
Fish and Wildlife Coordination Act (16 U.S.C. § 661 et seq.).
Knutson-Vandenberg Act of June 9, 1930 (16 U.S.C. 576, 576a-576b). §3 [16 U.S.C. 576b]
Bankhead-Jones Farm Tenant Act of 1937 (7 U.S.C. §§1010 et seq.)
Anderson-Mansfield Reforestation and Revegetation Act of October 11, 1949 (16 U.S.C. 581j (note), 581j, 581k)
Multiple-Use Sustained-Yield Act of 1960 (16 U.S.C. §§528 et seq.)
Forest and Rangeland Renewable Resources Planning Act (RPA) of 1974 as amended by the National Forest Management Act (NFMA) of 1976. §6
International Forestry Cooperation Act of 1990 (16 U.S.C. § 4501)
Healthy Forests Restoration Act of 2003 (H.R. 1904), [16 U.S.C. 6501-6502, 6511-18, 6541-42, 6571-78]
Wyden Amendment (P.L. 109-54, Section 434).
For brief descriptions of all these statutes, see the references and links at the end of this blog posting.
Advocates have tried before to legislate a specific requirement that federal agencies combat invasive species. The Federal Noxious Weed Act of 1974 (7 U.S.C. § 2801 note; 7 U.S.C. § 2814) was amended in 1990 to add §15, “Management of Undesirable Plants on Federal Lands”. This section requires each federal agency to
1) designate an office or person adequately trained to develop and coordinate an undesirable plants management program for control of undesirable plants on federal lands under the agency’s jurisdiction, and
2) establish and adequately fund an undesirable plants management program through the agency’s budgetary process,
3) complete and implement cooperative agreements with state agencies regarding the management of undesirable plant species on federal lands, and
4) establish integrated management systems to control or contain undesirable plant species targeted under cooperative agreements.
This approach hasn’t worked – no one is satisfied by the federal agencies’ “weed” management efforts.
What is missing is a political demand for action – and support for necessary staff and funding. Agencies under the secretaries of Agriculture and Interior bear most of the responsibility for managing invasive species. As long as these officials are not being pressed by key Congressional committees, the media, and key stakeholders to take more aggressive and effective action to curtail species introductions and suppress established populations of bioinvaders, they will continue to focus their attention on issues that do generate these kinds of political pressure.
I am not saying that the principal statutes governing invasive species management could not be improved. As noted above, several proposals have been put forward to strengthen laws which are the foundation for preventing introduction of invasive species. I will blog about specific proposals in the new year.

Invaders Put Another Bird at Risk

As noted in an earlier blog (“When Will Invasive Species Get the Respect They Deserve?” May 2016), invasive species can cause extinctions – especially on islands. I have posted other blogs about the invasional meltdown in Hawai`i (“Hawaii’s unique forests now threatened by insects and pathogens” October 2015).
A further demonstration of the meltdown is the decision by the US Fish and Wildlife Service (USFWS) to propose listing another Hawaiian honeycreeper (bird) – the i`iwi (Drepanis (Vestiaria) coccinea) as a threatened species. Already, some 20 Hawaiian forest birds are protected under the Endangered Species Act. Many, although not all, are threatened by the same factors as the i`iwi.
The proposal, which summarizes an extensive supporting report, is available here. USFWS is accepting comments on the proposal that are submitted to the USFWS’ website before November 21.
The proposal documents the tragedy of Hawai`i. The i`iwi was once almost ubiquitous on the islands, from sea level to the tree line. Today the bird is missing from Lanai; and reduced to a few individuals on Oahu, Molokai, and west Maui. Remaining populations of i`iwi are largely restricted to forests above ~ 3,937 ft (1,200 m) on Hawaii Island (Big Island), east Maui, and Kauai.
In the past, hunting for the bird’s striking red feathers and agricultural conversion doubtless affected the i`iwi’s populations. Since the early 20th Century, though, the threats have all been invasive species.
The USFWS has concluded that the principal threat is disease: introduced avian malaria — caused by the protozoan Plasmodium relictum and vectored by introduced mosquitoes (Culex quinquefasciatus). A second disease, Avian pox (Avipoxvirus sp.), is also present but scientists have not been able to separate its effects from those of malaria. Both vectored by the southern house mosquito.
I`iwi are very susceptible to avian malaria; in lab tests, 95% of birds died.

I`iwi alive now have survived because they live in forests at sufficiently high elevations; there, cooler temperatures reduce the numbers of mosquitoes, and thus transmission of the disease. However, the birds must fly to lower elevations in certain seasons to find flowering plants (the i`iwi feeds on nectar) – and then becomes exposed to mosquitoes.
Worse, climate change has already caused warming at higher elevations, and is projected to have a greater impact in the future. The rising temperatures predicted to occur – even if countries meet their commitments from the December 2015 meeting of the UN Framework Convention on Climate Change – will result in upslope movement of mosquitoes. As a result, according to three studies reviewed by the USFWS, the i`iwi will lose 60 – 90% of its current (already limited) disease-free range by the end of this century, with significant effects occurring by 2050.
I`iwi occur primarily in closed canopy, montane wet or montane mesic forests composed of tall-stature `ohi`a (Metrosideros polymorpha) trees or in mixed forests of `ohi`a and koa (Acacia koa) trees. The i`iwi’s diet consists primarily of nectar from the flowers of `ohi`a and several other plants, with occasional insects and spiders.
Hakalau National Wildlife Refuge; USFWS photo
The i`iwi’s dependence on `ohi`a creates another peril, because `ohi`a trees are vulnerable to alien diseases – both ohia rust and, especially, rapid ohia death or Ceratocystis ohia wilt. (Read descriptions of both diseases here. As of September 2016, rapid ohia death has been found only on Hawai`i – the “Big Island”. However, 90% of all i`iwi currently reside on the Big Island! Worse, in future the relatively large area of high-elevation `ohi`a dominated forest on the Big Island was expected to be the principal refuge of the i`iwi from the anticipated climate-driven up-slope movement of malaria. However, as just noted, the Big Island’s trees are now being killed by disease. If rapid ohia death continues to spread across the native `ohi`a forests – on Hawai`i and potentially on the other islands – it will directly threaten i`iwi by eliminating the limited, malaria-free native forest areas that remain for the species.
Rapid `ohi`a death (ROD) is caused by two distinct strains of the widely introduced pathogen Ceratocystis fimbriata. It was first detected in the Puna District of Hawai`i in 2012. The disease has since been detected across a widening area of the Big Island, including on the dry side of island in Kona District (See map here. The total area infested has increased rapidly, from ~6,000 acres in 2012 to 38,000 acres in June 2016. Since symptoms do not emerge for more than a year after infection, the infested area is probably larger. ROD kills `ohi`a in all size and age classes. There is no apparent limit based on soil types, climate, or elevation. O`hi`a growing throughout the islands appears to be vulnerable, from cracks in new volcanic areas to weathered soils; in dry as well as mesic and wet climates. The pathogen is probably spread by spores sticking to wood-boring insects and – over short distances – wind transport of insect frass.
Federal and state agencies are spending $850,000 on research on the disease, possible vectors, and potential containment measures. Additional funds would be needed to implement any strategies, and to expand outreach to try to limit human movement of infected plants or soil.
The Hawaii Department of Agriculture adopted an interim rule in August, 2015 which restricts the movement of `ohi`a plants, plant parts, wood, and frass and sawdust from Hawai`i Island to neighboring islands. Soil was included in the interim rule with an effective date of January 1, 2016. In March 2016, HDOA approved permit conditions for movement of soil to other islands. The interim rule is expected to be made permanent at a meeting of the Board of Agriculture on 18 October.
Other invasive species threatening the i`iwi are feral ungulates, including pigs (Sus scrofa), goats (Capra hircus), and axis deer (Axis axis). All degrade `ohi`a forest habitat by spreading nonnative plant seeds and grazing on and trampling native vegetation. Their impact is exacerbated by the large number of invasive nonnative plants, which prevent or retard regeneration of `ohi`a forest. Drought combined with invasion by nonnative grasses have promoted increased fire frequency and the conversion of mesic `ohi`a woodland to exotic grassland in many areas of Hawaii.
The feral pigs pose a particular threat because by wallowing and overturning tree ferns (Cibotium spp.) they create pools of standing water in which the mosquitoes breed. The US FWS has concluded that management of feral pigs – across large landscapes – might be a strategic component of programs aimed at managing avian malaria and pox.
One possible source of hope: research into genetic manipulation of the mosquito disease vector by using tools from synthetic biology and genomics (see draft species status report . Considerable research is probably necessary before such a tool might be implemented.
Threat of Plant Pest Threat to Endangered Animals is Not Limited to Hawai`i
The USFWS is struggling to deal with the threat posed by plant pests to listed species. In San Diego, California, FWS personnel are trying to decide how to address the threat posed by the Kuroshio shot hole borer (read description here to willows which constitute essential riparian habitat for the least Bell’s vireo.
Numerous cactus species that have been listed as endangered or threatened might be attacked by two insects from Argentina, the cactus moth and Harissia cactus mealybug (see my blog from October 2015; or read descriptions here .
Endangered Species Agencies Need to Coordinate with Phytosanitary Agencies
A growing number of species listed under the Endangered Species Act are being threatened by damage to plants from non-native plant insects and pathogens. This growing damage affects not just listed plants – such as the cacti mentioned in this and the October blogs; but also plants that are vitally important habitat components on which listed animals depend. The USFWS needs to engage with other federal and state agencies and academic institutions which are working to prevent introduction of additional plant pests, slow the spread of those already in the United States, and develop and implement strategies intended to restore plant species that have been seriously depleted by such pests. The USFWS should, therefore, work more closely with USDA Animal and Plant Health Inspection Service and Forest Service. USFWS must, of course, continue to work with experts in wildlife and wildlife disease.
Similarly, state wildlife agencies also need to coordinate their efforts with their counterparts in state departments of Agriculture and divisions of Forestry.
Many agencies in Hawai`i play crucial roles in protecting the Islands’ unique plant and animal communities:
U.S. Department of the Interior: Fish and Wildlife Service, National Park Service, United States Geological Service Biological Resources Division
US. Department of Agriculture: APHIS, Forest Service, Agriculture Research Service, National Institute of Food and Agriculture
US. Department of Homeland Security Bureau of Customs and Border Protection.
Hawai`i State Department of Agriculture and Department of Land and Natural Resources
Hawaiians of all types – federal and state employees and agencies, academics, and conservationists – deserve our thanks for promptly taking action of rapid ohia death. All parties should make every effort to obtain the remainder of the funds needed to carry forward crucial research on ROD and avian malaria. Those of us from the mainland need to support and help their efforts.

Fed up by lack of action on invasive species? Let’s pressure the right targets!
On December 1, the House Oversight Committee, Subcommittee on Interior, held a hearing on invasive species. This hearing was apparently held at the request of the ranking Democrat, Brenda Lawrence of Michigan. Ms Lawrence is most concerned about aquatic invaders in the Great Lakes. Chairwoman Cynthia Lummis is from Wyoming, so her focus is on invasive plants on western rangelands.
Chair Lummis opened the hearing, but left promptly. Other subcommittee members who were present for varying lengths of time were Paul Gosar (R-AZ), Ken Buck (R-CO), Gary Palmer (R-AL), Brenda Lawrence (D-MI), and Stacey Plasket (D-USVI) ; from full committee: Will Hurd (R-TX).
The witnesses were the newly appointed executive director of the National Invasive Species Council (NISC), Jamie Reaser; the president of the Reduce Risk from Invasive Species Coalition (RRISC), Scott Cameron; Dr. George Beck of Colorado State University, representing the Healthy Habitats Coalition (HHC); and Dr. Alan Steinman, expert on aquatic invaders from Grand Valley State University in Michigan.
This hearing followed those in past years that had been stimulated by the HHC. Both HHC and Congressional members expressed great frustration that the federal government is not putting sufficient effort into stopping or reversing the spread of invasive plants on western rangelands.
The December hearing – like its predecessors – focused the criticism on NISC. I think this focus is misguided. NISC has no independent authority or power; it was created to coordinate agencies’ actions, not to substitute for them. Its staff lack sufficient rank to tell agencies what to do.
In § 4 of Executive Order 13112, NISC’s duties are listed as providing national leadership through (a) overseeing implementation of this order, seeing that Federal agencies’ activities are coordinated, complementary, cost-efficient, and effective, …; (b) encouraging planning and action at local, tribal, State, regional, and ecosystem-based levels …; (c) developing recommendations for international cooperation …; (d) developing, in consultation with the Council on Environmental Quality, guidance to Federal agencies pursuant to the National Environmental Policy Act (NEPA)…; (e) facilitating development of a coordinated network among Federal agencies to document, evaluate, and monitor IAS impacts …; (f) facilitating establishment of an … information-sharing system …; and (g) preparing a national Invasive Species Management Plan every two years.
NISC has fallen far short of these requirements. It has not succeeded in developing guidance on NEPA – at least in part because CEQ has not cooperated. Most glaringly, NISC has issued only two Management Plans over 15 years — the most recent in 2009. All Members at the hearing complained to Reaser about this failure. Members see the Plan as key to setting priorities and ensuring that funds are well-spent.
All Members seemed to think that NISC actually should carry out on-the-ground activities and direct agencies’ priorities. Some want NISC to overcome federal agencies’ alleged foot-dragging in helping local groups eager to attack local problems, or to pressure Native American tribes to cooperate.
While I share the critics’ frustration about federal agencies’ inaction, I believe the productive approach is to apply pressure on – and where deserved, support for – those who have the authority and power to act, but who often choose not to. These are:
• heads of agencies and departments, especially the secretaries of Agriculture and Interior and their Under and Assistant secretaries;
• budget staffs of these and other relevant agencies;
• Members of the Congressional appropriations committees.
If these people think that dealing with invasive species is politically important, they will do so. If they don’t hear from their constituents about invasive species, they will focus on other issues.
At the hearing, Scott Cameron, of RRISC, said that what is missing is commitment at the Assistant/Under Secretary Level. Such a commitment would both drive coordination among agencies at headquarters and provide “cover” for regional staff trying to work together. He feels that a new Management Plan is useful but not sufficient. Scott made several recommendations intended to raise the political visibility of invasive species issues:
1) NISC submit annual work plan to Congress – he thought this would get political level attention in the departments;
2) NISC serve as forum to coordinate with regional governors’ associations;
3) NISC create national network of regional early detection/rapid response efforts;
4) NISC serve as forum for regional officials of land-managing agencies to coordinate and work together – this might succeed in getting attention of agency leadership and OMB;
5) NISC ensure coordination of priorities and approaches by member agencies at headquarters level; and
6) NISC evaluate best practices by other governments, propose their adoption by the United States.
Dr. Beck, of HHC, reiterated his constituency’s complaint that there has been little progress on invasive species problems despite three decades of effort. He blamed the lack of leadership by NISC – without saying how staff can “lead” the political appointees who head agencies! He called – again – for abolition of NISC and transfer of its $1 million budget to “on the ground” programs. Beck also decried inconsistencies in agencies’ budgets, lack of collaboration with states and local groups in setting priorities, and NEPA having become an excuse to avoid taking action.
HHC has promoted introduction of bills in both the House and Senate – H.R 1485 & S. 2240 – which would require:
• cooperation with states;
• categorical exclusion from NEPA review for efforts to protect high-priority sites;
• 5% annual reduction in weed species’ extent; and
• allocation of agencies’ invasive species funds according to the following formula: 75% for on-the-ground activity; 15% for combined research and outreach; 10% or less for administrative costs.
Of these recommendations, I think the proposed dropping of environment reviews of invasive species management programs – especially in “high priority” sites of high ecosystem values – would be a disaster. Management programs have environmental impacts, too; and some approaches cause more harm than good. For example, use of herbicides to eliminate knapweeds has sometimes resulted in takeover of the site by non-native annual grasses that are even more difficult to control.
Also, I think the proposed funding allocation is very unwise. Research and outreach often contribute enormously to control or containment of invasive species. I have been unable to get straight answers from the USDA Forest Service about how such an allocation would affect their programs – which are divided among three separate entities – Research, State and Private Forestry, and National Forest System.
HHC is very active in promoting its position – and those of us who think differently are not yet being heard in Congress.
I think there is room to work with members of the House Oversight Committee to focus more attention on the agencies’ political leadership – where it belongs and where pressure might have an effect. Rep. Lawrence seems interested in continuing efforts. Rep. Hurd of Texas asked about steps to prevent plant pest introductions (none of the witnesses knew about APHIS programs). Furthermore, a second Michigander, Rep. Dan Benisheck, and a Californian, Rep. Mike Thompson, co-chair the Invasive Species Caucus. Although none of them has yet expressed concern about tree-killing pests, given where they are from they might be persuaded to engage.
At present, the only Congressional champion for effective invasive species programs – especially as regards tree-killing pests – is Senator Leahy of Vermont. He has helped prevent further cuts in budgets for APHIS and USFS. We need more friends in Congress.
I urge you – and your friends! – to contact your Representatives and Senators to explain how invasive species are damaging important ecological and economic resources in your state. Ask them to work with their colleagues to support and improve federal programs aimed at preventing new introductions, containing species already introduced, and developing effective methods to reduce pests’ impacts and restore native forests.

New IUCN report notes invasive species threat to World Heritage Sites – Including U.S. National Parks
The World Conservation Union (IUCN) has just released a report, IUCN World Heritage Outlook 2014 (for press release, click here; for the full report, click here)
that names invasive species as the second most significant threat World Heritage sites with outstanding natural values. (Poaching is the greatest threat).
World Heritage sites have “outstanding universal values” – either natural or cultural. Natural sites are areas either of exceptional beauty or representative of major stages of Earth’s history, significant ongoing ecological processes, or significant habitats for biodiversity and threatened species.
The 2014 assessment examined 229 natural World Heritage sites and found that 104 are affected by invasive species. Unsurprisingly, island sites are especially heavily impacted. Two-thirds of the affected island sites (24 out of 36) are in the tropics.
The most widespread or common invaders are plants; they are named in 55 of the 104 affected sites. Invasive vertebrate animals affect at least 12 sites. These frequently include fish (mostly trout), cats, and rodents (especially rats).
The report calls for effective management strategies to protect the World Heritage sites. Such strategies include well-defined plans as well as strict bio-security measures, including limiting materials entering the site or the eradication of problem-causing species. Ideally, these actions involve local communities. Among the 104 natural World Heritage areas affected by invasive species, 87 have management projects addressing at least some invasive species or related issues.
According to the report, future invasive species management will be even more challenging, especially because of climate change. Climate change, itself, could become the biggest threat to natural sites in future.
dead sweetbay in Big Cypress National Preserve, Florida
The United States has 21 World Heritage sites. Nine were chosen for their outstanding natural values. These include the following National parks: Everglades, Grand Canyon, Great Smoky Mountains, Hawaii Volcanoes, Redwood, Yellowstone, and Yosemite National parks; and – jointly with Canada – Kluane / Wrangell-St. Elias / Glacier Bay / Tatshenshini-Alsek and Waterton-Glacier National parks.
Several of these natural wonders are well known to be threatened by invasive species – including some tree-killing insects and pathogens.
Everglades National Park. In Everglades, pythons have decimated populations of small to medium native mammals. Lionfish are killing vast numbers of fish in the shallow bay. Numerous invasive plants, especially Australian pine, Melaleuca, Brazilian pepper, and old world climbing ferns transform the natural sawgrass prairie and mangroves. Some, e.g., Melaleuca, are under control thanks to persistent effort over decades.
Laurel wilt has almost eliminated swamp bay trees from the hammocks. Bromeliad weevil has killed many bromeliads in 12 genera (of the 16 present in Florida).
Tillandsia utriculata bromeliad in Florida
Great Smoky Mountains National Park. The outstanding biological diversity of the forested Great Smoky Mountains National Park has been severely undermined by chestnut blight, hemlock woolly adelgid, balsam woolly adelgid; and is now under attack by more recent invaders, including beech bark disease, emerald ash borer, and thousand cankers disease of walnut. Descriptions of all these pests are available here. At ground level, feral hogs damage plants, soil-dwelling invertebrates and small vertebrates, even birds. Rainbow trout compete with native trout in the streams. More than 380 non-native plants compete with the native species. The Park’s website features another invader, the Asian jumping worm (Amynthas agrestis), which has been introduced through bait.
The Great Smoky Mountains are the center of biological diversity for salamanders which are likely soon to face danger from the “Bsal” pathogen – unless the Fish and Wildlife Service acts to restrict imports of salamanders by the pet trade. See how CISP tries to counter this threat.
Hawaii Volcanoes National Park. As I wrote in my blog of October 7, Hawaii Volcanoes National Park is fighting feral hogs, goats, and a plethora of invasive plants (the Park’s flora contains nearly twice as many exotic flowering plants as native species). The Park’s birds are threatened by two non-native diseases, avian pox and avian malaria. As noted in the earlier blog, Hawaii Volcanoes has also been invaded by koa wilt and `ohi`a rust; and is about to be invaded by `ohi`a wilt.
Web-based information from several parks in the western part of the continent focuses on the threat from invasive plants: Grand Canyon, Olympic, Yellowstone, and Yosemite. Redwoods National Park notes the damage caused by sudden oak death to its principal hardwood species, tanoak. Yellowstone National Park has a website describing its whitebark pine forests and mentioning that up to 30% of the taller whitebark pines have been attacked by white pine blister rust; I could find little information about the disease’s impact on the Park’s limber pines, which are also susceptible.
Yosemite National Park has a website with a table listing 16 non-native insects and pathogens that could threaten trees in the park. White pine blister rust is already present in the Park’s sugar pines. I am pleased to see that the website features goldspotted oak borer and the risk of pest introduction via firewood. I just wish Yosemite actually prohibited visitors from bringing firewood into the Park! And carefully restricted commercial suppliers! I addressed Yosemite’s failure to protect itself in my blog of 10 August.
The National Parks Conservation Association is the principal NGO that advocates for protection of the National parks. It issued a report in 2008 that found invasive species were a limited concern in 90% of the parks evaluated, a widespread or chronic concern in 38%. In Hawaii Volcanoes specifically, the natural resources were ranked in “poor” condition due primarily to non-native plants and animals.
Many individual parks have “Friends” groups ….
I ask these groups to help the National parks counter invasive species. To be effective, they need to go beyond the many volunteer “weed pulls” and outreach programs educating park visitors who might transport invasive species (for example, boaters and fishermen who can spread New Zealand mudsnails, rock snot, and invasive mussels; and campers who carry firewood that can transport pests). I ask them to also lobby for policies that would prevent invasions and for increase funding for the parks’ resource management programs (the programs that tackle invasive species). I suggest specifically that supporters of National parks advocate for improvements in programs run by the USDA’s Animal and Plant Health Inspection Service or the U.S. Fish and Wildlife Service. These agencies, more than any other, determine whether prevention succeeds or fails.
