„Erfassung des Einflusses invasiver Prädatorenarten auf die Vorkommen von besonders und streng geschützten Amphibienarten zwischen Jahrstedt und Wiepke

TENDER DESCRIPTION

Lot 1 comprises the survey area in the Drömling between Jahrstedt in the west, Wiepke in the north-east and Solpke and Dannefeld in the south. The area has a size of approximately 281.84 km², i.e. 2.21 full grid map sheets. Included are grid map sheet 3431 Parsau in part with approximately 30.45 km² and the grid map sheets 3432 Kunrau with approximately 125.62 km² and 3433 Solpke with approximately 125.77 km², each in full. Within the area, in 2027 as many suitable waters as possible are to be investigated systematically for the entire amphibian inventory and for indications of invasive predators, in particular raccoon and mink. Waters with high potential for species of Annexes II and IV of the FFH Directive are to be prioritised. At least three surveys are planned per grid map sheet; for each fully included grid map sheet, a total of twelve full field days are to be completed. At least 25 water bodies per grid map sheet are to be recorded as evenly as possible across the area and the grid map sheet quadrants. Mapping is to take place between mid-March or early April and mid-May 2027 partly at dusk and at night. The survey dates must be spaced 14 to 21 days apart. The…
