It is all the more astonishing how the area now presents itself: although drainage is still being carried out, some parts have become waterlogged again, and there are even occasionally large puddles under the modules. People rarely roam the area and there are no dogs on the premise so birds can breed in peace. The shepherd has already spotted curlews, snipes and ringed plovers, reports Gräfe. Due to the lack of pesticides, combined with the presence of wet areas, they find plenty of food. This has ensured the return of numerous plants and a variety of insects. "Even indicator species for moors such as cotton grass, moor willows and moor birches have settled," says the landscape architect.
Technical planning supports biotope development
However, it was not only protection from human and animal predators and the avoidance of pesticides that helped biodiversity. Technical planning also played an important role. "The first ground-mounted systems in particular were planned with a lot of extra space", Gräfe remembers. "We maintained large distances between the rows and almost overcompensated a little.” The advantage: rainwater can run off and seep away between the modules and the soil receives sufficient sunlight. "Experience shows that nature develops well between the modules if certain rules are adhered to," says Gräfe. Rules such as those laid down by the German Association of the New Energy Economy, which JUWI also follows.
