| Abstract | We proposed and developed 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 six watersheds on the Okanogan-Wenatchee and Colville National Forests. We investigated current year, lagged, and low frequency relationships between composite fire histories and Palmer Drought Severity Index (PDSI), Pacific Decadal Oscillation (PDO), and the Southern Oscillation Index (SOI) using superposed epoch analysis and cross-spectral analysis. We identified smaller scale controls on fire exerted by fuel limitations by comparing patterns of fire hazard over time on simulated landscapes without controls to landscapes in the six watersheds. We used spatial autocorrelation, geostatistics, and multivariate methods to quantify the spatial structures of fire regimes and how they depended on local topography. We documented clear differences in fire regimes between the historical period (ca. 1650-1900) and the period after initiation of fire suppression in the region (ca.1900). We developed a unique geo-spatial database that takes advantage of both the spatially explicit nature of the fire-history data and new paradigms in geographic information science. |
