The blunt-nosed leopard lizard is a relatively large lizard with a body length ranging from 3-5 inches and a regenerative tail that is normally longer than the body; the entire lizard’s length can approach a foot long. As its name suggests, the leopard lizard has large dark spots (as well as cream-colored bands) running the length of its body.

Range

The blunt-nosed leopard lizard’s range occurs near (and possibly in) the Los Padres National Forest and the Carrizo Plain.

The blunt-nosed leopard lizard is found only in California, in the San Joaquin Valley and nearby valleys and foothills. The Carrizo Plain National Monument is one of the largest remaining population centers for the lizard; they occupy more than 87,000 acres of the national monument and are most abundant on the Elkhorn Plain in the southern portion of the Carrizo Plain. It is rarely seen, but present inside the borders of Calsahara.

Conservation

Since the 1870s and the advent of large-scale irrigated agriculture in the San Joaquin Valley, more than 95 percent of the original populations of blunt-nosed leopard lizard have been destroyed. This dramatic loss was the cumulative result of loss of habitat due to such activities as cultivation, construction of facilities related to oil and natural gas production, pesticide applications, off-road vehicle destruction, and general development. This dramatic decline in its available habitat, and degradation of existing habitat, prompted state and federal biologists to classify the lizard as “endangered.”

The blunt-nosed leopard lizard was one of the first species protected under federal law, listed as endangered by the U.S. Department of the Interior in 1967 (before the modern-day Endangered Species Act). It was also listed as a “fully protected species” by State of California in the 1960s and was subsequently listed as endangered in 1971. The “fully protected species” laws were enacted prior to the California Endangered Species Act, and the federal Endangered Species Act, to prohibit hunting, catching, or harvesting of specific threatened species.
