Stock Photo - PRODUCTION - 13 July 2022, Baden-Wuerttemberg, Walldorf: Hans-Joachim Fischer, project manager of the crested lark monitoring in Walldorf, fills a water trough in the breeding area of rare crested larks. The Rhine-Neckar District Office had ordered that cats are not allowed to roam through the breeding area of the rare crested larks in the south of the town of Walldorf from April to August until 2025 - unless they are kept on a short leash or can be shown not to move in areas where they could become a danger to the birds, which are threatened with extinction.
