Woody plant biotopes in the middle of agricultural landscapes or large areas significantly increase the biological diversity. Many rare species like butterflies, beetles, reptiles and birds such as the Red-backed Shrike, or mammals such as bats need the woody plants as a protected breeding site and a base for hunting. The fruits of the bushes are an important basic food resource. Grasses and herbs at the edge of the woody plants and in the undergrowth are home to numerous insects that in turn provide food for other animals. In this way, even small woody plant biotopes result in large numbers of species.
