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. 

Restoration and Revegetation efforts for Portal Ridge Wildlife Preserve. Nearly 100 native shrubs and trees planted during this wet winter weather. Big thanks to our friends from Habitat Works for lending a hand! @blue6_fmt @americorpsnccc also key to a successful day
This month marks the 3rd Anniversary that #MojaveTrails #SandtoSnow and #CastleMountains were named #NationalMonuments !! Big gratitude to all those who worked hard to conserve these #PublicLands We support conservation designations like these, and we hope to celebrate them for many more years to come. Happy 3rd Anniversary!
We are absolutely thrilled to host an @americorpsnccc team this year. Our beloved Blue Six team has been rocking and rolling with us since January. They have assisted us in restoration, monitoring, cleanups, tortoise surveys, trail work, and education outreach. Big reward for them will be to experience a phenomenal spring bloom- poppy reserve and west mojave
Taking samples at Ahn Spring for an eDNA study. UCLA Postdoctoral Scholar, Maura Palacios Mejia, and her team spent a cold, beautiful day with our #portalridge preserve managers. #eDNA can help identify specific organisms that interact with a water source. Since we have extensive photo-documentation of a variety of animals using this spring, the UCLA team intends to utilize Ahn spring to help correlate their sample findings. 📷: Maura Palacios Mejia

Nicest kiosk on the block. Thanks to a @castateparksohv grant, we have been able to install three of these in the Fremont / Cuddeback region for OHV users and other desert visitors. Lots of good info on these
Big thank you again to @ancestrallands crew 655. The crew completed over 100 restoration sites and helped us protect 760 acres of desert habitat in our Fremont Peak project area. Dakota, Sheldon, Mercediz, Raina, and Merlin, we appreciate you- come back and visit us again sometime. #southwestconservationcorps @mc_rhetorik
Goodnight and rest well sweet Mojave. This weekend you will experience the busiest off-road activity of the year. This weekend, thousands of dirt bikes, jeeps, side-by-sides, quads, razors, RVs, and SUVs will cross your roads, traverse your open country, crush your vegetation, and cave in your wildlife burrows. People will enjoy themselves in the outdoors, and families will camp together. Many others will disregard or even destroy management signs and fences, and they may willfully or unknowingly damage private land. Plenty of people will be respectful and appreciative of this unique desert resource, but many others will not. Things will be shot, and fires will burn. Folks will get a chance to get out of the populated city areas and appreciate a clear night sky. Dust will be raised. Good luck sweet Mojave. We’ll be out there with you on the weekend, we’ll try to talk to folks, hand out information, help with incident response, and speak on your behalf. Then we’ll see you on Monday to help you recover.
Restoration day with our new pals from Habitat Works. Part of our ongoing project to resolve erosion problems in Portal Ridge. We planted 60 gray pines, California Buckwheat, manzanita, and yerba santa

Three adopted #deserttortoise enjoying their newly created burrows at our headquarters. We’ll be busy planting yummy native shrubs and grasses in their habitat while they are in brumation for the winter.
