Forest ecosystems are enormously important to mankind. They not only supply wood, foods, medicines, waxes, oils, gums, resins and tannins, but they also regulate climate, hydrology, mineral cycling, soil erosion, and cleansing of air and water. A variety of natural and human-…

Impacts of felling, mulching, and burning on budgets of C, N, S, P, K, Ca, and Mg; rates of CO2 evolution from the soil; soil seed storage; and plant growth were evaluated. The felled tropical evergreen forest was 8-9 yr old, interspersed with patches of 70 yr old forest and had…

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…

Two forest management objectives being debated in the context of federally managed landscapes in the U.S. Pacific Northwest involve a perceived trade-off between fire restoration and carbon sequestration. The former strategy would reduce fuel (and therefore C) that has…

We calculate greenhouse-gas emissions from land-use change in Mato Grosso and Rondônia, two states that are responsible for more than half of the deforestation in Brazilian Amazonia. In addition to deforestation (clearing of forest), we also estimate clearing rates and emissions…

In order to estimate the production of charcoal and the atmospheric emissions of trace gases volatilized by burning we have estimated the global amounts of biomass which are affected by fires. We have roughly calculated annual gross burning rates ranging between about 5 Pg and 9…

The effects of fire on nutrient release in wetlands prior to, during and afterwards are notably rare. We initiated a long-term and large-scale ecosystem study, driven by a large restoration program, to assess ecological effects of repeated fires on a nutrient-enriched, cattail-…

Fire is a worldwide phenomenon that appears in the geological record soon after the appearance of terrestrial plants. Fire influences global ecosystem patterns and processes, including vegetation distribution and structure, the carbon cycle, and climate. Although humans and fire…

Shaped by fire for thousands of years, the forests of the western United States are as adapted to periodic fires as they are to the region's soils and climate. Our widespread practice of ignoring the vital role of fire is costly in both ecological and economic terms, with…
