Erfassung des Einflusses invasiver Prädatorenarten auf die Vorkommen von besonders und streng geschützten Amphibienarten zwischen Harbke und Wulferstedt

TENDER DESCRIPTION

Extract from the description of services: ..... Lot 1 – Between Harbke and Wulferstedt The study area is located on the western border of Saxony-Anhalt between Harbke in the north and Wulferstedt in the south-east and has a total area of approximately 235.82 km2, which corresponds to an area of approximately 1.85 full topographic map sheets (in the average 127.3 km2/MTB). The objective of the service is to record the species group amphibians and their invasive main predators raccoon and mink at as many suitable waters as possible within the respective topographic map sheet (MTB), with waters that have a high potential for species listed in Annexes II and IV being treated as a priority. For the recording, at least 3 surveys are to be carried out per topographic map sheet, whereby for a survey of a complete topographic map sheet, 4 (preferably contiguous) field days must be completed (with 8 mapping hours each) (equivalent to one field day per survey and per MTB quadrants (MTB Q)). For the entire recording (at least 3 surveys), therefore 12 full field days are available per MTB. These must in any case be completed in full - regardless of the number of mapped waters. Due to the…
