Assessing Protection of Alaska’s Terrestrial Biodiversity. / : Corinne Smith et al. Protection of Alaska’s Biodiversity June 2006
'89% of Alaska is owned by the state and federal governments. We found that while 43.6% of Alaska is managed for high and medium levels of conservation, a disproportionate amount (41.3 %) of those lands occur at high elevations (above 510 m), which are typically less biologically diverse than low-lying areas. Across the state, 5 of 19 vegetation classes are insufficiently represented in the existing protected areas, and when examining vegetation classes within ecoregions, 16 of 19 are found to be insufficiently represented in at least one of the ecoregions in which they occur.'
Principal Lakes of the United States. / : Conrad D. Bue. U.S. Geological Survey, 1973.
'The United States has about 250 fresh-water lakes that are known to have surface areas of 10 square miles or more. Nearly 100 of these are in Alaska, and 100 in Minnesota, Wisconsin, Michigan, New York,, and Maine. Thirty-four fresh-water lakes, exclusive of the Great Lakes, are known to have maximum depths of 250 feet or more. Twenty of these are in Alaska, and Alaska undoubtedly has more lakes of that depth which have not been sounded.'

GAO: Abandoned Mines: Information on the Number of Hardrock Mines, Cost of Cleanup, and Value of Financial Assurances. / : Statement of Anu K. Mittal, Director Natural Resources and Environment Team, 2011.
GAO 'issued a number of reports and testimonies on various issues related to abandoned and current hardrock mining operations. This testimony summarizes some of the key findings of these reports and testimonies focusing on the (1) number of abandoned hardrock mines, (2) availability of information collected by federal agencies on general mining activities, (3) amount of funding spent by federal agencies on cleanup of abandoned mines, and (4) value of financial assurances for mining operations on federal land managed by BLM. In 2005, GAO recommended that BLM strengthen the management of its financial assurances, which BLM generally implemented. BLM also agreed to take steps to address additional concerns raised by GAO in 2008'.
'GAO's past work has shown that there are no definitive estimates of the number of abandoned hardrock mines on federal and other lands. For example, in 2008 and 2009, GAO reported that BLM and the Forest Service had difficulty determining the number of abandoned hardrock mines on their lands and had no definitive estimates. Similarly, estimates of the number of abandoned hardrock mine sites in the 12 western states and Alaska (where most of the mining takes place) varied widely because there was no generally accepted definition of what constitutes an abandoned hardrock mine site. In 2008, GAO developed a standard definition for abandoned hardrock mining sites and used this definition to determine that there were at least 161,000 abandoned hardrock mine sites in the 12 western states and Alaska, and at least 33,000 of these sites had degraded the environment, by contaminating surface water and groundwater or leaving arsenic-contaminated tailings piles.'

Arctic National Wildlife Refuge (ANWR)
CRS: Arctic National Wildlife Refuge (ANWR): An Overview. / : Laura B. Comay et al, 2018 In the ongoing energy debate in Congress, one recurring issue has been whether to allow oil and gas development in the Arctic National Wildlife Refuge (ANWR, or the Refuge) in northeastern Alaska. ANWR is rich in fauna and flora and also has significant oil and natural gas potential. Energy development in the Refuge has been debated for more than 50 years. On December 20, 2017, President Trump signed into law P.L. 115-97, which provides for an oil and gas program on ANWR's Coastal Plain. This report discusses the oil and gas program in the context of the Refuge’s history, its energy and biological resources, Native interests and subsistence uses, energy market conditions, and debates over protection and development. ANWR is managed by the U.S. Fish and Wildlife Service (FWS) in the Department of the Interior (DOI). Under P.L. 115-97, DOI’s Bureau of Land Management (BLM) is to administer the oil and gas program in a portion of the 19-million-acre Refuge: the 1.57-million-acre Coastal Plain, also known as the 1002 Area.
