The Wümme lowlands of Fischerhude directly adjoin the Borgfelder Wümmewiesen nature reserve in Bremen, another large-scale conservation project which has been completed in the meantime. In the 'Fischerhuder Wümmeniederung' the Wümme river branches out into several main channels and tributaries forming an inland delta. The region is extraordinarily important for meadowbirds and as a stopover for migratory birds (designated EU bird sanctuary) and as a potential habitat for otters. Around 50 % of this territory, especially in its most valuable area known as the 'wet triangle', meets the criteria for a bird breeding site of national importance (endangered species include Montagu's harrier (Circus pygargus), the common snipe (Gallinago gallinago), the blacktailed godwit (Limosa limosa), the curlew (Numenius arquata) and the sedge warbler (Acrocephalus schoenobaenus)). 

They are threatened by the intensification of land use and by hydraulic engineering measures. 

The objective of the project is the conservation and development of a large-scale damp meadow landscape as a near-natural floodplain with damp grasslands, reedbeds, meanders (inland delta) and oxbows.

So far almost all of the land in the core area has been acquired by the project executing agency and leased with stipulations allowing extensive use only. As one of the key habitat management measures, those dikes which had been constructed along the arms of the Wümme in the core area have been largely removed or moved back from the water. In order to further improve the ecological conductivity of the watercourse, various impounding weirs have been converted into stream ramps.
