Remote cameras along the enclosure fence documented the frequent use of the holes by the kangaroo rats. Stephens' kangaroo rats use burrows for nesting, resting during daylight hours, storing food, and eluding predators. Camp Pendleton will continue monitoring the population and managing the mitigation site, performing habitat enhancement actions inside and outside of the enclosure. Because much of their habitat has been paved over and fragmented by development, the SKR was listed as Endangered under the the US Endangered Species Act and Threatened under the California ESA in the 1980s. Fish and Wildlife Service (USFWS). Their significant contributions have made this project a success. In October 1988 the Stephens Kangaroo Rat (SKR) was listed as an endangered species by the U.S. The species is named after American zoologist Frank Stephens (1849–1937). While the site had been set aside for conservation of the kangaroo rat, it was overrun with non-native grasses that created unsuitable conditions for the animals. The species was listed as federally endangered in 1988 after half of the habitat it historically occupied was lost to residential, commercial, and agricultural development. You also grant your consent to our data collection practices. It is endemic to the Southern California region of the United States, primarily in western Riverside County. The Army Corps of Engineers has denied a permit for the Pebble copper and gold mine proposed in southwest Alaska. Fish and Wildlife Service (USFWS) to avoid negative impacts to the species as the result of mission related activities. We, the U.S. Endangered Stephens' Kangaroo Rat to Keep Protection. By Heather Richards and Mike Lee in Energywire These measures dramatically modified the extant habitat conditions, resulting in a sizable area of high-quality habitat dominated by forbs (flowering plants). The Stephens' kangaroo rat ( Dipodomys stephensi) is a nocturnal rodent that is unique to southwestern California. The elusive animals are known to inhabit some of the 125,000 acres (50,586 hectares) belonging to Marine Corps Base Camp Pendleton (Camp Pendleton), a training base located on the southwestern coastal plains of the Santa Ana Mountains in San Diego County that promotes combat readiness. Stephens’ kangaroo rat (or biological shorthand, SKR) occupies open, undeveloped grasslands in western Riverside and San Diego counties in southern California. The Stephens’ kangaroo rat was originally listed as an endangered species in 1988.

Fish and Wildlife Service will continue to protect the imperiled and declining Stephens' kangaroo rat (Dipodomys stephensi) as an endangered species, as disclosed in a decision to be published tomorrow. The construction of artificial burrows – measuring approximately three feet (one meter) deep and two inches (five centimeters) wide – inside the enclosure provided the animals with immediate shelter, while remote cameras installed in and around the enclosure allowed personnel to monitor the kangaroo rats and track predator activities. Holding fence in the SKR management area. In addition, biologists fitted the translocated animals, as well as any additional kangaroo rats captured during ongoing monitoring surveys, with unique ear tags to allow for easy identification over time. Citing habitat protection progress in Southern California, the Fish and Wildlife Service today proposed bouncing the Stephens' kangaroo rat from endangered … To track the survival and movement of the translocated animals, biologists fitted each individual with a Passive Integrated Transponder (PIT) tag to allow its specific identification during surveys. Recent trapping surveys indicate that the population is colonizing and successfully reproducing in the adjacent habitat outside of the enclosure. A series of artificial burrows were also installed in the open grasslands surrounding the enclosure to provide immediate shelter for dispersing kangaroo rats. Hill, Creating a Safe Haven for Stephens' Kangaroo Rat at Camp Pendleton.
