Verbessrung des SPA 'Rieselfelder Muenster'

Description: Das Projekt "Verbessrung des SPA 'Rieselfelder Muenster'" wird vom Umweltbundesamt gefördert und von Biologische Station Rieselfelder Münster durchgeführt. The idea is to close the currently easily accessible core area to visitors. Simply banishing the inhabitants of Muenster city from one of their favourite recreation spots is however impossible unless this is balanced by a compensatory measure. Therefore, the project will develop an adjoining 150 ha site, which will permit pedestrians, cyclists and birdwatchers to observe the core area and its avifauna from a respectful distance, and simultaneously bring about an expansion of the wetlands available to the birds. As a result, the Rieselfelder SPA will almost double in size and link up to two nearby nature reserves. The site to be developed, currently arable land, is donated by the City of Muenster; LIFE will fund the investment in the works needed to transform it. These include the establishment of a 22 ha lake with nesting islets, several expanses of shallow water whose levels will be allowed to fluctuate and 40 ha of humid meadows and marsh, to be grazed by an Auerochs herd. To round off, visitor infrastructure (paths, observation platforms) which is as unobtrusive as possible, will of course be built. That humans not only destroy natural habitats, but also, perhaps with very different intentions, occasionally create some, is illustrated by the saga of the Rieselfelder Muenster. It begins in 1901, when a chessboard of hectare-sized dyked and drained basins was laid out to receive sewage water from the city of Muenster. As this water flowed through the basins, it was purified by microbial metabolism and percolation through the subsoil. As time passed, waterfowl and waders discovered the eutrophic waters of this biological treatment system and, given the lack of alternatives in this intensively farmed region, it became an important inland staging area for migrating birds. However, in 1975 a mechanical treatment plant was opened and the Rieselfelder were henceforth irrigated with the clean water emitted by this plant. The 233 ha site was designated SPA, but simultaneously became a tourist attraction and favorite spot for walks. That is its paradox: before 1975 the site was left to the birds on account of its overpowering stench of sewage, but now, thanks to the wastewater treatment plant which eliminated the smells, visitors (up to a thousand a day) have become a serious source of disturbance for the nesting and resting birds. Urgent action is required.
