Capability to represent effects of fertilization has been added to the Prognosis Model for Stand Development. As implemented in version 6, the extension is calibrated only for applications of 200 lb nitrogen applied in the form of urea. Direct and indirect effects are based on growth 10 years aft...

Permanent plots were established in the Greater Yellowstone Area (GYA) following the 1988 fires to determine response of bark beetles to fire-injured conifers. Within 2 years (1989 and 1990), 67 percent of the Douglas-fir had been infested by bark beetles (primarily the Douglas-fir beetle) and wo...

Greater knowledge is needed about visitors to federally classified wilderness in the South, the reasons they visit wilderness, and the ways wilderness conditions influence their experiences. This information will allow areas within the region to be compared, and it will improve the potential for ...

Numbers of suckers produced following burning of aspen stands varied greatly between areas but followed similar trends over a 6-year period: a relative abundance the first year, followed by an abrupt decline by the third year and a gradual decline thereafter. First-year sucker numbers that ranged...
