Integrated Conservation Planning for Cetaceans (ICPC) is a volunteer group of conservation professionals formed in response to the desperate situation facing critically endangered dolphin and porpoise species. Many of these species and populations have distributions that entirely overlap areas used intensively by people. Most of those species are declining due to unsustainable numbers killed in gillnets. For some, we know that extinction is imminent without determined and swift action to save them. The overarching goals of ICPC-supported initiatives are to fill critical knowledge gaps, then develop and help to implement integrated conservation plans for the most threatened dolphin and porpoise species and populations.
