A severe natural windstorm followed by a high intensity forest fire caused significant increases in runoff and in losses of nitrogen, phosphorus, and potassium from two small Precambrian watersheds. Both the windstorm and the fire had significant…

On September 11 and 12, 1973 a severe forest fire burned over a number of watersheds in the area west of Salmon Arm, B. C. The hydrologic effects of this forest fire were assessed using streamflow data for one stream draining a small watershed with…

The effects of burning no nitrogen (N) losses and transformations in red pine (Pinus resinosa Ait.), eastern hemlock [Tsuga canadensis (L.) Carr.], and Douglas-fir (Pseulotsuga menziesii)/western larch (Larix occidentalis Nutt.) forest floor were…

Damage from tractor logging and slash burning in a Douglas-fir stand on gentle terrain was measured for three different types of timber harvesting. Logging damage was light in the selection-cut and understory-removal cutting units. In the overstory-…

This report summarizes available information on fire as an ecological factor for forest habitat types occurring on the Lolo National Forest. The Lolo National Forest habitat types are grouped into 10 Fire Groups based primarily on fire's role…

Historical evidence indicates that fires were prevalent in grasslands. In the past, big prairie fires usually occurred during drought years that followed l to 3 years of above-average precipitation, which provided abundant and continuous fuel. Fire…

Base line data on species cover (m /0.01 ha) and volume of space occupied (m /0.01 ha) for the initial 6 to 9 years of secondary forest succession for western larch-Douglas-fir forests is presented in tabular form for 20 study areas in western…

Slash burning in a clearcut under conditions producing very light to light burn intensities (<150°F or 66°C) for a short duration did stimulate resprouting, but resulted in almost no enrichment of biologically essential nutrients in the foliage.…
