Conservation of Populations and Species


The conservation of populations and species requires that we identify how many and which populations have the greatest value, and then determine effective strategies for minimizing the threats to those populations. In many instances human activities have so severely imperilled species, that we must turn to habitat restoration, captive breeding, and largeā€scale ecosystem management to accomplish the goal of biodiversity protection.

Keywords: biodiversity; population viability; conservation; endangered species; extinction
