Transition Habitat Conservancy
Our mission: Transition Habitat Conservancy protects areas of critical habitat, transition zone and wildlife corridor ecosystems and their scenic, agricultural, and cultural resource values in the West Mojave Desert. We participate in programs improving our knowledge of the Mojave Desert ecosystem. We also provide education about the fragile and inspirational nature of our desert plants, animals, and ecosystems to connect people to nature.

We need your help! It takes people like you to make this work. Each gift brings us closer to saving our most beautiful and important places. All donations are tax deductible! Consider leaving a lasting legacy by putting THC in your will or estate plan. To make a monthly recurring gift please call

Some of our activities

We work in sensitive ecological regions. For more information read the THC's Mojave Ecoregional Assessments for Western North America, and the Recommendations of Independent Science Advisors for The California Desert Renewable Energy Conservation Plan (DRECP).


Our goal is to preserve pristine places in the High Desert and along the San Gabriel rift zone -- including the rich biodiversity, threatened species, and wildlife corridors -- for the enjoyment and inspiration of generations to come.
