U.S. Fish & Wildlife Service3 Billion Birds Summary Map Layer. This layer powers the exploratory tool which provides a crosswalk of continental-level U.S. Fish and Wildlife Service Birds of Conservation Concern (BCC 2021) species, Road to Recovery (R2R) class, and Species of Greatest Conservation Need (SGCN) for each state that also appear on these lists. In this layer, the priority- or tier-level of a SGCN species within any given state's plan was not considered. If the SGCN species was a BCC and/or R2R species, it was simply noted that it matched at least one of those two criteria.
