FORESTED WETLAND: Priority Species
Population estimates and targets (numbers represent individuals
unless otherwise indicated) for priority species within forested
wetlands in the Mid-Atlantic Coastal Plain. Estimates were
extrapolated from BBS relative abundances unless otherwise
indicated; they should be considered an index of relative
population sizes and only a VERY APPROXIMATE estimate of true
population sizes.
