Abstract

In this study, the AA. tested the influence, in species distribution models (SDMs), of predictors derived from a very high resolution (VHR) digital elevation model (DEM) by comparing the predictive power of models for 239 plant species and their assemblages fitted at 6 different resolutions in the Swiss Alps. They also tested whether changes of the model quality for a species is related to its functional and ecological characteristics. The results suggest that improving resolution of topographic data only is not sufficient to improve SDM predictions – and therefore local management – compared to previously used resolutions (here 25 and 100 m). More effort should be dedicated now to conduct finer-scale in-situ environmental measurements (e.g. for temperature, moisture, snow) to obtain improved environmental measurements for fine-scale species mapping and management
