Combustion products of burning vegetation can increase seed germination of many species of fire-prone plant communities. We tested the influence of heating sagebrush (Artemesia tridentata Nutt.) subcanopy soil, aqueous extracts of artificially burned soil, and sagebrush smoke on…

In 1985, Yosemite began using a geographic information system for fire management and research. The system has been used to compare historic fire incidence over a range of topography and vegetation types. Parkwide fuel inventories and prescribed burn units have also been…

Soil CO2 flux (JCO2) was measured at midday over a 2-yr period in undisturbed tallgrass prairie (Konza Prairie, Kansas, USA) to quantify seasonal and annual budgets, to evaluate temperature and moisture as determinants of soil CO2 flux, and to assess the effect of a common land…

Boreal peatlands occupy about 1.14 x 106 km2 in North America. Fires can spread into peatlands, burning the biomass, and if moisture conditions permit, burning into the surface peat. Charred layers in peat sections reveal that historically bogs in the subhumid continental…

Despite increasing temperatures since the end of the Little Ice Age (ca. 1850), wildfire frequency has decreased as shown in many field studies from North America and Europe. We believe that global warming since 1850 may have triggered decreases in fire frequency in some regions…

Climate, vegetation, and fire are interrelated so that any change in one will affect the others. Increases in greenhouse gases, especially carbon dioxide, are expected to increase average surface temperatures and alter precipitation patterns. These changes will alter numerous…
