Bird conservation plans are organized by taxa, with comprehensive 'all birds' conservation plans now available in a number of BCRs. Landbird conservation plans in the west were done by state, whereas those in the rest of the country were done by Partners in Flight (PIF) physiographic area. Shorebird plans were done by shorebird planning regions, which generally represent amalgams of BCRs. Waterbird plans were done by waterbird conservation planning regions, which also represent amalgams of BCRs. Waterfowl plans were done by joint venture area based on waterfowl areas of importance.
