To celebrate National Hispanic Heritage Month (September 15-October 15), we are taking the opportunity to highlight Latinx leaders working in conservation who inspire us!

Today we are featuring Sergio Avila! We asked him to share about his career path and his experiences as a person of color working in conservation.

Sergio was born in Mexico City (1972) and grew up in Zacatecas, Mexico. He’s an immigrant to the United States, living in Tohono O’odham and Yaqui lands, known as Tucson, Arizona. He was first hired by the University of Arizona in 2004, and became a U.S. Citizen in 2016.  Sergio is a husband, son, brother, uncle and cousin; a trail runner; and an outspoken justice and equity advocate.

Sergio holds a Master’s degree (Arid Ecosystems Management & Wildlife Research) from University of Baja California; and a Bachelor’s in Biology (University of Aguascalientes), both in Mexico. For twenty-five years, Sergio has worked on regional conservation efforts along the U.S.-Mexico borderlands. His varied experience includes living with the Indigenous Tarahumara of the Sierra Madre (1998), and ranching communities of Sonora (2003), which transformed his vision of environmental stewardship and conservation. Avila tracked and studied borderland jaguars and ocelots in the southwest United States and northwest Mexico for 10 years. Two live encounters with jaguars in the mountains of Sonora were life-changing experiences that shaped Sergio’s personal and professional life. He has led efforts to protect Monarch butterflies’ migration, studied Cactus-ferruginous pygmy-owls in the Sonoran Desert, and mountain lion predation on bighorn sheep in Baja California. 

Throughout his career, Sergio has felt invisible, alone, and not represented in the environmental and conservation communities as a person of color, feeling forced to ‘code switch’ and ‘fit in’ in spaces, instead of feeling true belonging. While studying borderland jaguars and monitoring the impacts of border wall construction, Avila became directly aware of U.S. immigration policies and enforcement. Continued racial profiling, harrassement and threats by the U.S. Border Patrol caused Avila to stop jaguar research along the borderlands. Due to personal and professional events like those described above, Sergio left conservation science and now works with the Sierra Club as an advocate for equitable and inclusive outings programs that allow underrepresented communities to enjoy and protect Nature, elevate Traditional Ecological Knowledge, and shine a light to broader engagement opportunities than the typical scientific or recreational interests of the dominating white conservation movement.

Sergio admires Arizona Congressman and Chair of the Natural Resources Committee in U.S. Congress, Raul Grijalva. An inspiring leader, decision-maker and representative who demonstrates that conservation and care for the environment does not require an academic degree, diplomas or publications.


Thank you so much to Sergio for sharing his experiences with us. You can keep up with him by following him on Instagram.
