Abstract
  • The effects of prescribed burning on the abundance, species composition, and reproduction of small mammals were studied over a one year period. Two burn areas were studied, one in sagebrush/ bunchgrass and one in cheatgrass. The short-term effects were studied using monthly mark-recapture trapping on two treatment and two control areas totaling 9600 trap nights, with 1208 individuals captured 3650 times. The effects of the fires after a one year period were studied by continuous 15 day removal trapping at two burn and two control areas prior to burning and one year later. Removal trapping totaled 30, 000 trap nights with 3994 individuals captured. Results indicated that the number of individuals actually killed in the fires was insignificant. In general, the fires had no major effects on the small mammal communities in terms of species abundance, age and sex ratios, weights and reproductive condition.
