This research developed a multi-scale analysis of the relationships between climate, topography, and spatio-temporal patterns in historical fire regimes in the Inland Pacific Northwest.
We used existing fire history data from seven watersheds on the Okanogan-Wenatchee and Colville National Forests. Clear differences in fire regimes between the historical period (1650-1900) and the period after initiation of fire suppression in the region (after 1900) were documented.
We acknowledge funding provided by the Joint Fire Science Program under Project JFSP 01-1-6-01.
This project addressed tasks 6 and 7 of the Joint Fire Science Program request for proposals 2001-1 by linking climate to fire regime characteristics and by developing spatially explicit, empirically based tools for predicting fire risks as a function of climatic conditions. We proposed a multi-scale analysis of the relationships between climate and topography and spatio-temporal patterns in historical fire regimes in the Inland Pacific Northwest, using existing fire history data from the Okanogan-Wenatchee and Colville National Forests.
A broad-scale relationship exists between fire occurrence and drought in eastern Washington.
