Marine Mammal Species and Populations of Concern
A central focus of our mission is to ensure marine mammals are restored and maintained as functioning elements of healthy marine ecosystems. We pay special attention to marine mammal species and populations considered to be most vulnerable to human activities, at greatest risk of extinction, or in greatest conflict with people.
