<P> This species was declared endangered on both the federal and California state levels in the 1980s . It inhabits less than a mere 2 % of its original range and can now be found only in isolated areas west of the San Joaquin Valley , including the Carrizo Plain , the Elkhorn Plain , and the Kettleman Hills . The giant kangaroo rat , like many other rodent species , lost much of its habitat as the Central Valley fell under agricultural use . Much information still needs to be obtained regarding their basic biology and compatibility with various land uses before clear directives can be made . Besides some projects currently underway in the Carrizo Plain National Monument , studies need to be conducted on populations whose range overlaps with private lands . Recovery of the giant kangaroo rat can be achieved when the three largest populations in eastern Kern County , Carrizo Plain Natural Area , and the Panoche Region along with the populations in the Kettleman Hills , San Juan Creek Valley and Cuyama Valley are protected and managed appropriately . </P>
