Under federal law, local governments are compensated through various programs for reductions to their property tax bases due to the presence of most federally owned land. These lands cannot be taxed, but may create demand for services such as fire protection, police cooperation, or simply longer roads to skirt the federal property. Some of these programs are run by specific agencies and apply only to that agency's land. The most widely applicable program, administered by the Department of the Interior (DOI), applies to many types of federally owned land, and is called "Payments in Lieu of Taxes," or PILT. The authorized level of PILT payments is calculated under a complex formula. This report addresses only the PILT program administered by DOI. There is no PILT-like program generally applicable to military lands, but a small fraction of military lands are eligible for the DOI PILT program. Furthermore, PILT does not apply to Indian-owned lands, virtually none of which are subject to local taxes. This report explains PILT payments, with an analysis of the five major factors affecting the calculation of a payment to a given county. It also describes the effects of certain changes in PILT in 2008. Previously, annual appropriations were necessary to fund PILT, but a 2008 provision (in P.L. 110-343) for mandatory spending ensured that, beginning with FY2008 and continuing through the payment to be made in 2012, all counties will receive 100% of the authorized payment. On July 6, 2012, the President signed P.L. 112-141, containing a provision extending mandatory spending to FY2013. Other issues have been the inclusion of additional lands under the PILT program, particularly some or all Indian lands, which are not now eligible for PILT. Most categories of Indian-owned lands cannot be taxed by local governments, though they generally enjoy county services. In some counties, this means a very substantial portion of the land is not taxable. The remaining tax burden (for roads, schools, fire and police protection, etc.) therefore falls more heavily on other property owners. To help compensate for this burden, some counties have proposed that Indian lands (variously defined) be included among those eligible for PILT payments. Examples of other lands mentioned from time to time for inclusion are those of the National Aeronautics and Space Administration, and the Departments of Defense and Homeland Security. In addition, some counties would like to revisit the compensation formula to emphasize a payment rate more similar to property tax rates (which vary widely among counties), a feature that would be a major change in counties with high property values. Finally, for lands in the National Wildlife Refuge System (NWRS), some have argued that all lands of the system should be eligible for PILT, rather than limiting the PILT payments to lands reserved from the public domain and excluding PILT payments for acquired lands. The exclusion of NWRS-acquired lands affects primarily counties in eastern states. With the extension of mandatory spending to FY2013, the program would return to funding through annual appropriations in FY2014. Over the next few years, the larger debate for Congress might then be summarized as three decisions: (1) whether to approve future extensions of mandatory spending (either temporary or permanent); (2) whether to make the diametrically opposed choice of reducing the program through appropriations or changing the PILT formula; and (3) whether to add or subtract any lands to the list of those now eligible for PILT payments. Background on all three issues is discussed here.

The explosion of the Deepwater Horizon drilling rig in the Gulf of Mexico on April 20, 2010, and the resulting oil spill began a cascade of effects on the coastal areas of the Gulf and on the wealth of species that inhabit those areas. These wetlands, like those elsewhere, have value for water quality, flood control, shoreline protection, and recreation. They serve as nurseries for many species, including fish and shellfish of commercial significance, waterfowl, and a host of resident and migratory species. They also have cultural importance to the people of the Gulf. The effects of the spill come on top of historic wetland losses due to subsidence, drainage, and saltwater intrusion, along with rising sea levels, coastal erosion, and global climate change.

The Endangered Species Act (ESA) protects species identified as endangered or threatened with extinction and attempts to protect the habitat on which they depend. It is administered primarily by the Fish and Wildlife Service and also by the National Marine Fisheries Service for certain marine and anadromous species. Dwindling species are listed as either endangered or threatened according to assessments of the risk of their extinction. Once a species is listed, legal tools are available to aid its recovery and to protect its habitat. The ESA can become the visible focal point for underlying situations involving the allocation of scarce or diminishing lands or resources, especially in instances where societal values may be changing, such as for the forests of the Pacific Northwest, the waters in the Klamath River Basin, or the polar environment. This report discusses the major provisions of the ESA, both domestic and international, and also discusses some of the background issues, such as extinction in general, and the effectiveness of the statute.

Bees, both commercially managed honey bees and wild bees, play an important role in global food production. In the United States, the value of honey bees only as commercial pollinators in U.S. food production is estimated at about $15 billion to $20 billion annually. The estimated value of other types of insect pollinators, including wild bees, to U.S. food production is not available. Given their importance to food production, many have expressed concern about whether a "pollinator crisis" has been occurring in recent decades. In the United States, commercial migratory beekeepers along the East Coast of the United States began reporting sharp declines in 2006 in their honey bee colonies. The U.S. Department of Agriculture (USDA) reports that overwinter colony losses from 2006 to 2011 averaged more than 32% annually. This issue remained legislatively active in the 110th Congress and resulted in increased funding for pollinator research, among other types of farm program support, as part of the 2008 farm bill (P.L. 110-246). Congressional interest in the health of honey bees and other pollinators has continued in the 112th Congress (e.g., H.R. 2381, H.R. 6083, and S. 3240) and may extend into the 113th Congress. This report: Describes changes in managed and wild bee populations, given readily available data and information. It focuses on managed and wild bees only, and excludes other types of pollinators, including other insects, birds, and bats. Data on managed honey bees are limited, and do not provide a comprehensive view of changes in bee populations. Data for wild bee populations are even more limited; Provides a listing of the range of possible factors thought to be negatively affecting managed and wild bee populations. In addition to pesticides, other identified factors include bee pests and diseases, diet and nutrition, genetics, habitat loss and other environmental stressors, and beekeeping management issues, as well as the possibility that bees are being negatively affected by cumulative, multiple exposures and/or the interactive effects of each of these factors; Briefly summarizes readily available scientific research and analysis regarding the potential role of pesticides among the factors affecting the health and wellbeing of bees, as well as the statutory authority and related regulatory activities of the U.S. Environmental Protection Agency (EPA) related to pesticide use. A 2007 report by the National Research Council of the National Academy of Sciences, Status of Pollinators in North America, provides a more detailed scientific context for this report and may be consulted for more in depth understanding about bee health. That study concluded that many factors contribute to pollinator declines in North America, and CRS accedes to that conclusion. Accordingly, the focus of this report on bee exposure to pesticides is not intended to imply that pesticides are any more important in influencing the health and wellness of bees than any of the other identified factors influencing bee health. Pesticides are only one of the many influences on bee health. Because neonicotinoid pesticides have been the focus of concerns in Europe and in the United States, this report briefly describes recent scientific research related to possible effects of exposure to these pesticides on bees. The report concludes with a summary of recent regulatory activity regarding neonicotinoids at EPA, the federal agency charged with assessing risks and regulating U.S. sale and use of pesticides.
