Regional bark beetle windthrow and snow breakage disturbance predisposition maps

Regional disturbance predisposition maps for windthrow, bark beetle and snow breakage. The maps are created using spatially explicit data of classified forest structure and site factor parameters. The classified input parameters were weighted according to their effect on windthrow, bark beetle and snow breakage predisposition using an expert-based model. The predisposition raster maps (10 x 10 m) represent the sum of expert-weighted effects on the predisposition and are provided as raw values (sum of the effects on predisposition) and as classified layers. Classified predisposition maps are encoded as follows: 1: low predisposition (-50% quantile based on raw predisposition values) 2: increased predisposition (50–75% quantile) 3: high predisposition (-75–95% quantile) 4: extreme predisposition (-95% quantile) Also included are the derived forest structure maps for development stage, dominant stand height, number of stems and canopy cover used for the predisposition mapping, as well as the R scripts and example data to re-create these parameters. Forest structure parameters are based on a data set of individual trees detected using a high-resolution vegetation height model. Further
