The 1982 Bureau of Land Management (BLM) peregrine falcon (Falco peregrinus tundrius) nesting survey was a continuing effort to visit active and historic peregrine falcon nesting sites within the National Petroleum Reserve-Alaska (NPR-A) (see Figures 1 and 2). Raptor surveys within NPR-A have been conducted periodically since the early 1950s, with yearly surveys being conducted since 1978. The 1982 survey was a continuation of previous efforts to locate and document peregrine falcon and other raptor species within NPR-A.
