Document Summary
Preventing extinction is not enough, the ultimate goal must be recovery. Recovering species have: self-sustaining wild populations, resumed their ecological roles: predators, prey. Key steps to recover imperiled species: document that the species is declining, study the basic ecology and natural history. 2 major estimation approaches: area-based sampling- count # in random subject of total study area (ex. Florida maratee, whale transects, aerial transects: mark-recapture: (ex. Proportion of study area x probability of detection(ranges from 0 to 1) M= number of individuals in first sample n= size of second sample m= number of previously marked individuals in second sample m/n = m/n.
