The Großweberbach nature reserve covers more than 20 hectares of streamside meadows. The wetlands and spignel meadows preserved there are important habitats for numerous species and at the same time a relic from agricultural production in earlier times. The low-nutrient soils in the Bach Valley were watered by the farmers in spring with spring water and thus received important nutrients. In late summer, they were then mowed, which led to the formation of a productive lawn at these points. In addition, this extensive use allowed new and, at times, unusual, fauna and flora to form. In order to preserve this valuable natural area, the Natagora nature conservation association and its local offshoot Natagora/BNVS have bought up numerous plots on the Großweberbach and take care of the upkeep of the area. The Großweberbach Valley can be explored on numerous hiking routes.
