During the 9th International Conference on Wildlife Fertility Control, BIWFC Advisory Board and Conference Committee member Cheryl Asa was presented with the 2022 Trailblazer Award. This award recognizes and honors an individual who has had a profound impact on our field, one who has an exemplary reputation, and one who serves as a model, especially for emerging practitioners and researchers.

The name of this award is appropriate in both the figurative and literal sense. Cheryl has devoted 30+ years to research, writing, and teaching to advance an understanding of reproductive strategies, their differences and adaptive value. Cheryl established and served as director of the Association of Zoos and Aquariums (AZA) Reproductive Management Center, formerly the AZA Wildlife Contraception Center, for over 27 years. She concurrently directed the Saint Louis Zoo’s Reproductive and Behavioral Sciences Department.

For more than 20 years, Cheryl supervised 27 graduate and post-doctoral students and taught courses in Animal Behavior at Washington University and in Endocrinology and Behavioral Endocrinology at Saint Louis University. Cheryl has published 180 scientific articles, co-edited the book Wildlife Contraception: Issues, Methods and Application, and was lead author on the Fertility Control chapter of the National Academy of Sciences report on feral horse management.

Even in retirement, Cheryl continues to blaze trails in wildlife fertility control. In addition to her service to The BIWFC, she chairs the AZA Reproductive Management Center Advisory Board and is a Scientific Advisory Board member of the Found Animals Foundation and the Alliance for Contraception in Cats and Dogs, as well as the IUCN Equid and Canid Specialist Groups.

Colorado Governor to Speak at Conference

We are excited to announce that The Honorable Jared Polis, Governor of Colorado, will speak at the 9th International Conference on Wildlife Fertility Control at the Cheyenne Mountain Resort in Colorado Springs, CO. Governor Polis will address the conference attendees at 10:30 AM on Monday, May 23.

Governor Polis is an entrepreneur, education leader, public servant, and Colorado native. After launching several successful companies, including one out of his college dorm room, Polis committed himself to making sure other Coloradans had the opportunity to pursue their dreams. Polis founded schools for at-risk students and new immigrants and started nonprofits to help veterans and entrepreneurs.

Prior to serving as Governor, Polis served on the State Board of Education where he worked to raise pay for teachers and reduce class size for students, and represented Colorado’s 2nd Congressional district, where he was rated the most effective member of the Colorado delegation.

As Governor, Polis has focused on saving Coloradans money, keeping their economy strong, and preserving their Colorado way of life. Polis delivered universal free full-day kindergarten, signed a number of bills to save families money on health care, and made significant progress towards the goal of 100% renewable energy by 2040, all while cutting taxes for small businesses and investing in affordable housing and transportation. His efforts to expand health care access to medically underserved communities and to ensure that equity and justice remain central to building a Colorado for All have produced impactful legislation and made progress toward his administration’s bold vision.
