The Rieselfelder Windel Nature Reserve, with an area of 102.34 hectares, is located in the western part of Bielefeld. It was designated a nature reserve (NSG) in 2014 by a landscape plan. It is the largest private nature conservation project in the greater Bielefeld area, located in the former sewage fields of the Windelsbleiche district, part of the Senne district. It is funded by the Rieselfelder Windel Foundation, a non-profit, dependent nature conservation foundation under the fiduciary management of the Ravensberg Nature Foundation, based in Bünde. The nature reserve includes the Ortmann farmstead and another building, which are not part of the nature reserve. The Gütersloh/Bielefeld Biological Station was established in a barn building at the Ortmann farmstead in 1997. An information center is located in an adjacent building. The southern part of the nature reserve is separated by the Landstraße 788 (state road). Part of the Autobahn 33 borders it to the west. The Schwarzes Venn Nature Reserve borders the area to the west, separated only by a road. The Windel sewage fields are characterized by their diverse biotopes: wet and dry, open and wooded habitats, and the low intensity of land use are responsible for a wide variety of species living there, from bearded reed tits and kingfishers to spadefoot toads and lesser gargoyles to barn owls and little grebes. Two unpaved circular trails, the information center centrally located in the fields, guided tours, activity days, and nature education events for children and young people offer visitors opportunities to experience the sewage fields. The Windel Sewage Field Foundation also collaborates with the Osthusschule Museum.
