Over the past several years, Molycorp has partnered with the National Park Service, the National Park Trust, and Chevron to help create the Ivanpah Desert Tortoise Research Facility, located approximately 10 miles from Molycorp’s Mountain Pass, California Rare Earth Facility. The Desert Tortoise Research Facility helps to shelter young desert tortoises. Molycorp donated the land for the facility, and Chevron generously financed the facility’s construction.
In September 2014, the partners formally dedicated the Facility in an event that featured a field trip by several dozen fourth and fifth grade students from schools in Baker, CA and Henderson, NV. The students were taught about desert tortoises and other native species in the Mojave desert, and were able to witness the release of some juvenile tortoises into the wild.
The National Park Service will now manage the facility while scientists from University of California-Davis and the University of Georgia-Savannah River will conduct research. The facility includes a LEED Silver-certified laboratory building, two acres of predator-proof tortoise enclosures containing native vegetation, and seven acres of high-quality tortoise habitat.

New Ivanpah Desert Tortoise Research Facility
Designed specifically for scientists to conduct research into juvenile tortoise survival, the Ivanpah Desert Tortoise Research Facility includes a LEED-certified laboratory building, four enclosures consisting of two acres of outdoor predator-proof tortoise holding pens containing native vegetation, and seven acres of high-quality tortoise habitat.
Research toward desert tortoise recovery
Desert tortoise populations continue to decline despite decades of protection efforts after their listing as a Threatened Species in 1990. There are many factors contributing to their decline in numbers. Scientists at the Ivanpah research facility are focusing on the problem of low recruitment: many juvenile tortoises never make it to maturity, hindering the ability of populations to rebound.
Scientists have identified predation, especially by ravens and coyotes, as a major cause of mortality during the first several years of life, before shells harden. Raising hatchlings in captivity until they are better able to resist predation, then releasing them into the wild, is known as headstarting.
While this practice improves juvenile tortoise survival rates, little is known about the efficacy of this program in reversing the population decline. Continual use of headstarting to maintain a declining population may not be logistically feasible, but temporary use to augment a depleted population could potentially “jump-start” a localized recovery, provided that the threats causing the original decline have been mitigated.
Scientists at the Desert Tortoise Research Facility will study these issues and develop repeatable protocols should they find that headstarting could help bring about the recovery of this species.
In 2009, Chevron began collaborating with the National Park Service and Molycorp to design and construct a facility for desert tortoise research, including a LEED-certified building and state-of-the-art predator exclosures to house juvenile and gravid female tortoises. Chevron constructed the first predator-proof tortoise holding pens in 2010; construction of the research facility building was completed in March 2011.
The National Park Trust, a non-profit organization, began managing the facility on behalf of the National Park Service in 2012, and continued in this role until transfer of the land title was complete. The building will be dedicated on September 4, 2014.
In 2011, scientists from the University of Georgia’s Savannah River Ecology Lab and the University of California, Davis initiated long-term headstarting research using mitigation funds provided by Chevron and support from other grants.
