Buena Vista Lake Shrew

Buena Vista Lake Shrew

The Buena Vista Lake shrew (Sorex ornatus relictus), a subspecies of the ornate shrew, is federally listed as an endangered species. Shrews have a long snout, tiny bead-like eyes, ears that are concealed, or nearly concealed, by soft fur, and five toes on each foot. Ornate shrews occur throughout the Central Valley and Coast Range in California. The Buena Vista Lake shrew formerly occurred in the wetlands that existed around edges of Buena Vista Lake and may have also occurred throughout the Tulare Basin. The habitat requirements are generally like those of other ornate shrews, thick understory vegetation with downed logs and branches, with an abundance of leaf litter and detritus.

San Joaquin (Nelson's) Antelope Squirrel

State listed as threatened, San Joaquin antelope squirrel (Ammospermophilus nelsoni) is one of five species of antelope squirrel that occurs in the arid regions of the southwestern United States and Mexico. The San Joaquin antelope squirrel can be distinguished from the co-occurring California ground squirrel by much smaller size; shorter, less bushy tail with a flattened shape rather than the bottle-brush shape of the California ground squirrel; and the presence of a light-colored stripe along the sides of the body. San Joaquin antelope squirrels inhabit arid annual grassland and shrub communities, including saltbush scrub and Valley sink scrub. They are most numerous in areas with a sparse to moderate cover of shrubs.
