Kevin Willis has served the zoological community for decades in a variety of posts, including time with the Association of Zoos and Aquariums, as one of our most important statisticians. His work is documented in peer-reviewed publications and essays across a multitude of terrestrial and aquatic species, from elephants to orcas. His greatest skill seems to be explaining and applying statistical principles to complex conservation questions in a manner the rest of us can easily grasp. He describes some of the history, key figures, and rationale behind the formation of Species Survival Programs (SSP), their original purpose, and where conservation biology and statistics stand today.  Animal Care Software
