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.

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.

Office Habitat! Our team of amazing volunteers and staff have been working hard this month to complete a #monarchwaystation and a #deserttortoise enclosure at our office in Pinon Hills. First photos are the butterfly habitat created by Girl Scout Troop 1334. Second batch is our three newly adopted tortoises in their new home.
Props to @joshuatreemusicfestival for providing ‘This Land’ as a place for organizations like ours to share our conservation efforts with the festival folks. We had a good time talking #tortoise issues at #JTMF and we met some great people. Thank you!
Wonderful team gathering seed, assessing a future restoration site, hiking on the land In #portalridge
