For this project, she is still searching for additional underwriters.

Jillian Cowles

I came to Arizona from Massachusetts at the age of 18 in a third-hand Chevy van, in the hopes of seeing a Gila monster in the wild. I rapidly fell in love with the desert, the big sky, the warmth, and best of all, the interesting variety of native plants and animals. I also fell in love with my spouse of almost 40 years, Bill Savary. I obtained a Bachelor's degree from the University of Arizona, and have been working as a clinical microbiologist at what is now known as Banner University Medical Center, Tucson for close to 3 decades. In my spare time, I started to build a photographic database of the plants and animals of southern Arizona. The arachnids proceeded to hijack this project, with the result that I am now working on a book on arachnids of the southwestern USA that will be published by Princeton University Press. And by the way, I did get to see not just one, but many Gila monsters since coming to Arizona. Some dreams really do come true.

Mirna Manteca

Mexico Conservation Biologist, Sky Island Alliance

Hiking and camping through the stunning Sonoran sky islands every summer as a child triggered my profound love for open spaces and wildlife. My wild childhood lead me directly to study biology in University of Sonora. I recently worked alongside CONANP (Comisión Nacional de Áreas Naturales Protegidas. the Mexican equivalent of the National Park Service. )in the wildlife monitoring department of Ajos-Bavispe National Forest Reserve and Wildlife Refuge. Using remote cameras and track identification techniques we monitored the priority species of Sierra Los Ajos. I also worked in beaver and black- tailed prairie dog monitoring and conservation efforts in the San Pedro Watershed along with Naturalia. I’m a conservation biologist committed to protecting the natural heritage of an amazing region between two countries with a broken relationship. Bringing the science to the decision makers on the ground, empowering young professionals to rise up and work towards protecting the land they live in and collaborating with partners with diverse backgrounds for the benefit of conservation has become my expertise. Currently I am Mexico Conservation Biologist with Sky Island Alliance, where I work cross-border with local landowners, federal and state agencies, academia and partner NGOs to protect landscape permeability and ensure water availability for human and wildlife use. 

Steve Marlatt

Vice-Chair of the Advocates for Snake Preservation Board of Directors
Steve’s passion for snakes began in college, when a wildlife professor happened to bring in a few animals and enlightened the class as to how unique, amazing, and misunderstood they truly are. He was instantly hooked! During his 26 years of teaching middle school science, snakes became an integral part of his curriculum. He has found that while many adults already have a fear and loathing of snakes, that is not an established perception in young people and they are fascinated and receptive to finding out more about them. Throughout the years, his students learned their traits, behaviors, diets, care, and how they were all individuals. Steve is also a founding board member of Gray Hawk Nature Center, which has introduced and educated thousands of students to the amazing world of snakes. He has a BS degree in Wildlife Management and a MA in Education from New Mexico State University
