Transition zones in fragmented landscapes - an approach to close the gap between single-ecotope models
The detection of land-use types in fragmented landscapes is widely applied using remotely sensed data. The boundary of different land-use types is most often depicted as a line or edge. However, highly contrasting ecosystems – for example agricultural fields and adjacent forests – might have abiotic gradients perpendicular to their boundary line. The gradients in these transition zones are said to affect ecosystems services, for example carbon storage, crop yield, or biodi-versity.
Understanding and defining the location and scope of these transition zones is done by ana-lysing data from field measurements. This data is subsequently used to calibrate remote sensing products in order to allow an upscaling of the results and to falsify, calibrate, or validate a model approach for abiotic factors in transition zones.
The greater goals are twofold: we want to 1) find an approach to allow a smooth integration of the model approach for abiotic factors in transition zones for existing ecotope models and 2) upscale the results to be applicable at landscape scale to make predictions on the spatial extent of altered ecosystem services in transition zones.
