Fires affect animals mainly through effects on their habitat. Fires often cause short-term increases in wildlife foods that contribute to increases in populations of some animals. These increases are moderated by the animals’ ability to thrive in the altered, often simplified, structure of the postfire environment. The extent of fire...
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...
Field studies were conducted during January, February and March of
1976 and 1977 to evaluate the effects of a prescribed burning program on
mule deer at Lava Beds National Monument. Visual observation, radio-telemetry
and pellet-group plots were utilized to investigate deer distribution,
food habits, movement patterns and behavioral responses to...
Shallow subsurface flow and surface runoff are spatially and temporally variable in forested environments. The location and timing of this runoff depends on both site characteristics (e.g., vegetation, soil texture, geology, and topography) and on time-varying conditions (e.g., soil water content, precipitation type, duration, magnitude, and intensity). Forest management activities...
Riparian forests in the Idaho Panhandle, north of Whitebird, were surveyed for rare riparian lichen species. The region was stratified into nine geographic units and by stream size. Eighty-one plots were surveyed for lichen community, stand and river characteristics. Variables important to lichen community composition included regional differences, elevation, climatic...
Once lost, a species can never be recovered, and there is no way of knowing how useful it may have been. We do know that human beings and many of their industries depend on plant and animal products. About 50% of all pharmaceuticals have a natural component as an active...
