The annual costs attributable to large fire suppression in three Forest Service Regions (1970-1981) were estimated as a function of fire perimeters using linear regression. Costs calculated on a per chain of perimeter basis were highest for the Pacific Northwest Region, next highest for the Northern Region, and lowest for the Intermountain Region. Recent costs in real terms for the Intermountain and Pacific Northwest Regions are lower when adjusted for fire sizes, indicating that cost calculations based on pre-1976 data may overestimate current costs.
A cost-aggregation approach has been developed for determining the cost of Fire Management Inputs (FMls)-the direct fireline production units (personnel and equipment) used in initial attack and large-fire suppression activities. All components contributing to an FMI are identified, computed, and summed to estimate hourly costs. This approach can be applied to any FMI by any organization with fire protection responsibility. Significant cost differences were found not only among the three State fire organizations studied, but among the three administrative regions within the Forest Service. Hourly suppression cost estimates ranged from $40 per hour for a small engine and 2-person crew in the Southwestern Region to $595 per hour for a 20-person Category II crew in the Pacific Northwest Region. The overhead, basic training, facilities, and equipment cost components were responsible for most of the cost variations.

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.
