Summary of Methods: Rodent predation on Lassen antelope bitterbrush (Purshia tridentata) seedlings was studied in burned and unburned antelope bitterbrush communities in California in 1993. Rodent densities were estimated at 15/ha in the burned habitat, and 14/ha in the unburned habitat, using the minimum known number alive method. Ord's kangaroo rat (Dipodomys ordii) was the species captured the most (n=13), followed by deer mice (Peromyscus maniculatus) (n=8), and Great Basin pocket mice (Perognathus parvus) (n=7). Rodents significantly decreased antelope bitterbrush recruitment through grazing and disturbance of the seedlings.
