Stock Photo - PRODUCTION - 25 November 2022, Brandenburg, Cottbus: Christoph Haase, project manager of the Tree University of the Fürst-Pückler-Museum Park and Castle Branitz Foundation, sits in the Old Tree University of the historic castle nursery at a bed of young twig oaks (Quercus cerris). Sick and dying trees, desert-like regions - with climate change, landscapes are visibly changing. Historical gardens and parks have also long been threatened. A rescue mission in Branitz Park continues the work of garden artist Hermann Fürst von Pückler-Muskau.
