Tricia Snyder

Rio Grande Campaigner

Tricia, as a child of military parents, spent much of her childhood moving frequently in the U.S. and abroad, but calls El Paso, TX home. Growing up on the banks of the (often dry) Rio Grande and the water scarcity of the Southwest sparked a life-long interest in finding solutions for water conflicts in the arid and semi-arid American West. Tricia received a B.S. in Geography with a focus on human-environment connection from New Mexico State University. Her research while there centered on water management across borders. She spent 5 years working with the Southwest Environmental Center working to protect and restore the wildlife and wild places of the Southwest borderlands, particularly focused on the recovery of the Mexican gray wolf. In 2015, Tricia moved to Washington state to pursue a graduate degree, receiving an M.S. in Cultural and Environmental Resource Management from Central Washington University. Her thesis, which conducted an adaptive capacity assessment of the Upper Klamath Basin, utilized both quantitative and qualitative research methods. She worked for nearly four years on salmon recovery as the Lead Entity Coordinator for the Yakima Basin in central Washington, bringing together a diverse group of interests and perspectives. Tricia joined WildEarth Guardians as the Rio Grande Campaigner in 2021.

Rebecca Vitale Mandich

Member, Board of Directors

Rebecca Vitale Mandich of Palo Alto, CA and Tesuque, NM, was called early to the environmental movement to give voice to the voiceless. An advocate since the 70s, she received her degree in Environmental Studies taught by some of the big thinkers of the time such as Paul Ehrlich, Stewart Brand, Dr. Richard Leakey, Alan Chadwick, and Dr. Donald Aitken, who founded the program at SJSUC as one of first in the nation. Utilizing that education, coupled with commitment and inspiration, Rebecca started taking actions from working in one of the first solar energy homes to working on ballot measures for better public transportation systems in the Bay Area. She assisted in opening the first Spanish-speaking office for Clinton/Gore campaign in 1992 and registered many in the local Hispanic community, hosting then candidate VP Gore to discuss the environment and community issues. In the meantime, she married Mitch Mandich and has two grown children, Matthew and Madeleine, and various dogs and cats have graced their lives. Having traveled extensively, her favorite escape is camping in our national parks and on public monuments and lands, where she has experienced all manner of wildlife and wild places. She became acquainted with WildEarth Guardians about six years ago when she read an article in the San Francisco Chronicle about their lawsuit against U.S. Fish and Wildlife services regarding wolves. She sent them a letter and a fast friendship formed over their mutual love of all things wild. Rebecca sees much hope in the future of the environmental movement that began with “Save the Whales" to now promoting a food and energy paradigm for the sustainability of natural resources. A deep political will and an openness to examine new ideas dictate her thinking. She feels that embracing environmental changes through engagement, both politically and through grassroots efforts, are paramount for the evolution of a responsible species to continue the ride on, what she affectionately refers to as, Spaceship Earth.
