Patterns of undisturbed nutrient cycling in northern ecosystems and the impact of fire on nutrient cycling are reviewed and discussed. The various effects of fire on ecosystem nutrient cycling may be broadly subdivided into (1) nutrient redistribution during fire, and (2)…

'Two studies were undertaken. An initial study in 1974 produced results that indicated significant losses of nitrogen and some other elements. The study was repeated 1981 as a check on the results of the 1974 burn, and to provide an assessment of the methods used in the first…

In this paper we briefly review current knowledge concerning the possible consequences of a changing climate for terrestrial ecosystems. Forests and grasslands of western North America figure prominently in the discussion, but our intent is to consider general principles rather…

Airborne measurements of 13 trace gases from seven forest fires in North America are used to determine their average emission factors. The emission factors are then used to estimate the contributions of biomass ubrning to the worldwide fluxes of these gases. The estimate for NH3…

Wild and prescribed fires currently burn about 20,100 ha per year in Washington west of the Cascade Crest: prehistoric wildfires burned an estimated 19,200 ha per year. Modern burning consumes 38 g/m²/yr of fuel; the estimated prehistoric rate was 35 g/m²/yr over a 50-percent…

Forest fires can be divided into two broad classes-wildfires and prescribed fires. Wildfires, whether caused by nature (lightning, etc.) or by the accidental or malicious acts of man, are not planned by forest managers and do not occur under controlled conditions. They can be…
