Transition Habitat Conservancy is a grassroots, non-profit organization that focuses on land acquisitions and habitat stewardship in the West Mojave. With the support of the local community, a dedicated board and staff, and successful partnerships with local, state and federal agencies, THC has acquired over 7,000 acres of important habitat and works to improve thousands of additional acres in Southern California.

Our Vision: By 2050, we will have protected several areas of ecological significance, including wildlife corridors and transition zones, within the West Mojave. We will also establish multiple natural parks in an effort to preserve hiker and equestrian access for people in the high desert communities so they may continue to enjoy our natural world and see for themselves these rich resources.

Protecting transition zones with elevational gradients, such as where the desert floor integrates with the mountain slope, may provide climate refugia opportunities for species of the desert.

New land acquisition! 10 acres of pristine, roadless habitat now stewarded by THC. This land is quite close to our #deserttortoise hotspot. Every little bit counts. #mojavedesert #conservation
Our rescue tortoises catching that warm morning light. Their habitat enclosure is really coming along this summer.
Collecting and planting joshua tree seeds on previously cleared land. You can see the dividing line where the yucca woodland was cleared for agriculture a few decades ago.
Joshua tree seeds! Tis the season to collect and disperse them in ideal places. Best success is to place seeds under shrubs- on the north side of the shrub. Cover under a couple centimeters of dirt. Let’s help propagate this iconic desert tree. We are doing this on former agricultural fields in the Antelope Valley.

Big step taken today for #SB307 It passed the appropriations committee, and now will reach the senate floor for a vote by May 31. Thank you senators! Please do the right thing and pass this bill.
Action Alert‼️ Please call CA State Senator Toni Atkins today (like right now) to urge support for SB307. The Cadiz water project is a destructive plan to pump Mojave Desert water to Orange County and will likely impact this amazing desert oasis. This new bill will require a true environmental impact review to ensure that sound science informs decisions instead of company shareholders and compromised politicians allowing the projects to occur. This bill must pass out of the Appropriates Committee by Thursday to have a chance of passing, and Senator Atkins holds the keys to that next step. Senator Atkins: (916) 651-4039 Thank you!
And another one. Acquisition alert‼️ 80 more acres in Portal Ridge. This completes our combined 120 acres added to the Preserve thanks to a key grant from the California Wildlife Conservation Board. A lovely ephemeral stream meanders through the lower portion of this land.
