During the spring and summer of 1994 we monitored soil-atmosphere exchanges of methane and carbon dioxide at upland sites in the Canadian boreal forest near the northern study area (NSA) of the Boreal Ecosystem-Atmosphere Study (BOREAS). The effects of fire on methane and carbon…

Thinning of forest stands is frequently used to reduce the risk of catastrophic fire. But thinning requires that the refuse (or slash) be removed from the site, which can be done either by burning it or by mastication and dispersal. Either method has long term consequences to…

From introduction: Wildfire is a majoar natural disaster in the United States. In 2002, for example, tens of thousands of wildfires occurred that consumed nearly seven million acres of forest and other land cover (NIFC, 2003). Wildfires contribute to increasing atmospheric CO2…

Forest structure and species composition can differ dramatically among stands in the same climatic zone, implying differences in ecosystem function. We used eddy covariance, physiological measurements, forest census plots and simulation models to contrast carbon dynamics and…

In Florida, natural communities require periodic fires for maintenance of their ecological integrity. Because of public concerns, wildfires can no longer be allowed to perform this mandatory function so prescribed burning is essential to manage these plant and animal communities…

Wildland fire is a major disturbance in most ecosystems worldwide (Crutzen and Goldammer 1993). The interaction of fire with climate and vegetation over long time spans, often referred to as the fire regime (Agee 1993; Clark 1993; Swetnam and Baisan 1996; Swetnam 1997), has…
