Avian Conservation Assessment Database
The Avian Conservation Assessment Database (ACAD) contains biological information used and generated by the Partners In Flight (PIF) Species Assessment Process, a peer-reviewed, scientific methodology for evaluating information related to the conservation of birds. The PIF Population Estimates Database provides breeding population estimates for all landbird species in the continental USA and Canada at various spatial scales (e.g., global, regional, state/provincial). ACAD uses Bird Conservation Regions (BCRs) as the geographic scale for regional assessments in the U.S. and Canada, but other regions are used in Mexico and countries are used in Central America. The vast majority of these estimates are derived from the North American Breeding Bird Survey (BBS). The Population Estimates Database and corresponding Handbook are products of the PIF International Science Committee and are intended to serve as a companion to the Partners in Flight Landbird Conservation Plan (Rosenberg 2016). The assessment scores can be viewed online, or downloaded with additional information.
