A simulation model was developed to estimate postfire changes in the production and value of grazing lands in the Northern Rocky Mountain-Intermountain region. Ecological information and management decisions were used to simulate expected changes in production and value after wildfire in six major rangeland types: permanent forested range (ponderosa pine), transitory range (Douglas-fir, larch, lodgepole pine, western white pine), mountain grassland, sagebrush, pinyon-juniper, and western hardwoods. Changes varied widely in quantity and duration among the range types. The largest decrease in net value was calculated for mountain grassland ($7/acre for a 2-year period). The largest increase in net value was calculated for a ponderosa pine sawtimber stand with 100 percent basal area removal ($36/acre for a l50~year period). The estimates calculated in this study should be useful in land and fire management planning in the Northern Rocky Mountain-Intermountain area.

In a 1964-1967 study on the Challenge Experimental Forest, seedfall was evaluated in 2-, 5-, and 10-acre circular clearcuttings. During the 4 years, 10 seed crops, ranging from light to bumper, were produced by ponderosa pine. white fir, Douglas-fir, and incense cedar. Seedfall ranged from 76 to 40,691 sound seed per acre (188 to 100,547/ha) for a single species in a given year. From 89 to 100 percent of each species' seed fell within an area 1 1/2 times the height of the average dominant tree. Overall, seed distribution was highly variable.
