Data were derived from hand drawn maps of bird focus areas, based on expert opinion, delineated during a workshop attended by 70 bird conservation experts, representing governmental and non-governmental organizations from the United States and Canada, in Rockland, ME, December 3-5, 2002. The purpose of the workshop was to identify priority bird species, the priority habitats needed by these priority species, begin discussion of a process for setting population and habitat goals, and define focus areas for the Atlantic Northern Forest Bird Conservation Region (i.e., BCR 14). The digital Bird Focus Area maps were based on the hand-drawn maps completed during the December 2002 workshop and were produced by Mark Anderson (The Nature Conservancy, Boston, MA), who worked with biologists in states and provinces in BCR 14 to refine polygon shapes, sizes, and exact boundaries. Randy Dettmers (USFWS, Hadley, MA) updated the BCR 14 focus areas for Waterfowl in February 2006 based on the revised 2005 ACJV Waterfowl focus areas.
