Abstract

To clarify broad-scale patterns and controls of treefall directionality from Hurricane Katrina, the AA. examined fall direction across a 4,500 km2 landscape mosaic in southern Mississippi using georeferenced, planar-rectified aerial photographs. Analyses using directional statistics, measures of local spatial autocorrelation, and general linear modeling indicated that treefall was significantly directional for nearly all locations and constrained primarily by mesoscale surface wind directions and landscape setting. When coupled with results from other studies focused on hurricane-caused damage, these results suggest that it is possible to develop empirical landscape-scale models of wind impacts or stand vulnerability using basic site information (topography, soils), biotic conditions (land cover, forest attributes), and generalized, but readily available, estimates of surface wind flow patterns
