Reconstructing Environmental Impacts of Fire from the Holocene Sedimentary Record I outline quantitative approaches to the reconstruction of the impacts that fires may have had on environmental variables during the Holocene. An important distinction in considering the environmental impacts of fires is between natural fires and fires initiated by humans for forest destruction and

The Sedimentary Record of Fire in Montane Meadows, Sierra Nevada, California, USA: a Preliminary Assegional fire periods and their relationship to climate during the Holocene. With the exception of the period of 8700 to 9200 yr BP, charcoal is less frequently encountered in early Holocene sediments than it is in sediments deposited after 4500 yr BP. We hypothesize a climatic control. Empirical and

Charcoal abundances change at or immediately preceding pollen zone boundaries which delineate plant community change. Vegetation stability in the northern coni

Proposed Bio-geological and Chemical Based Terminology for Fire-altered Plant Mattered. It is recommended that certain terms that have precise meanings in other fields should be either used with caution or discarded. Several existing terms should be disregarded, because they pre-suppose a mode of formation or structure for which the evidence is poor or incorrect.

Reconstruction Of Paleo-Fire Through Climate And Eco-System Modelsecosystem, and second, requires that we assume that current models of fire behavior will apply. These key assumptions can be restated as hypotheses: can current modeling capability reproduce paleo-fire? and, can climate models, coupled with ecosystem models and fire models, replicate the spatial patterns of fire emissions?

Characterization of Particulate Products of Biomass Combustionss burning studies, with particular emphasis on the carbonaceous material. For each method we review the principles, problems and uncertainties and, when possible, discuss analytical features presently or potentially applicable to characterizing both airborne and sediment particles.
