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

TENDER DESCRIPTION

Lot 1 comprises the investigation area in the Drömling between Jahrstedt in the west, Wiepke in the north-east and Solpke and Dannefeld in the south. The area has an area of approximately 281.84 km² and 2.21 full map sheets. The map sheet 3431 Parsau is included in part, with approximately 30.45 km², and the map sheets 3432 Kunrau with approximately 125.62 km² and 3433 Solpke with approximately 125.77 km² in each case in full. Within the area, in 2027, as many suitable waters as possible are to be systematically surveyed for the entire amphibian inventory and for indications of invasive predator species, in particular raccoon and mink. Waters with high potential for species listed in Annexes II and IV of the Habitats Directive are to be processed with priority. For each map sheet, at least three site visits are planned; for each fully included map sheet, a total of twelve full terrain days are to be completed for this purpose. At least 25 waters per map sheet are to be recorded as evenly as possible across the area and the map sheet quadrants. The mapping is carried out between mid-March and/or early April and mid-May 2027, partly at dusk and at night. The site visit dates must…
