Dry pold\u00ader near Stolzenhagen<\/p><\/div>\nT<\/span>he 1,680 hectare Lunow-Stolper Pold\u00ader and the 650 hectare Friedrich\u00adsthaler Pold\u00ader (5\/6) are typ\u00adi\u00adcal dry pold\u00aders. They are com\u00adplete\u00adly sealed off from flood\u00ading by dykes. But that does not mean that they are com\u00adplete\u00adly dry. They too are criss-crossed by numer\u00adous oxbow lakes, on the banks of which ani\u00admal and plant life are con\u00adcen\u00adtrat\u00aded. In addi\u00adtion, when the water lev\u00adel is high in the riv\u00ader or, water repeat\u00aded\u00adly seeps into the dry pold\u00ader via the ground\u00adwa\u00adter or through the dike foot, which is low\u00ader in the south than the mid\u00addle Oder water. There\u00adfore, water is con\u00adstant\u00adly pumped from the dry pold\u00ader into the Stro\u00admod\u00ader or the Hohen\u00adsaat\u00aden-Friedrich\u00adsthaler Wasser\u00adstra\u00dfe via the pump\u00ading stations.\nThe main\u00adte\u00adnance and devel\u00adop\u00adment plan for the dry pold\u00aders does not pro\u00advide for these pold\u00aders to be opened to nat\u00adur\u00adal flood\u00ading. For nature con\u00adser\u00adva\u00adtion rea\u00adsons, an open\u00ading of the dike at least tem\u00adporar\u00adi\u00adly in the Lunow-Stolper dry pold\u00ader would be desir\u00adable, but the dry pold\u00ader is too deep or the riv\u00ader or its bot\u00adtom is now too high. If the dike on the riv\u00ader Oder were opened, the dry pold\u00ader would fill up when the water lev\u00adel on the Oder was appro\u00adpri\u00adate. How\u00adev\u00ader, the Lunow-Stolper Pold\u00ader is to be grad\u00adu\u00adal\u00adly con\u00advert\u00aded to pure grass\u00adland man\u00adage\u00adment, so that at least in the event of extreme floods this pold\u00ader could also be flood\u00aded in order to cut the high water tip of the Oder. The flood\u00ading of arable areas would be prob\u00adlem\u00adat\u00adic because of ero\u00adsion and the entry of chem\u00adi\u00adcal fer\u00adtil\u00adiz\u00aders and pes\u00adti\u00adcides into sur\u00adface waters. Such a strat\u00ade\u00adgy would increase the reten\u00adtion areas for extreme floods; it serves flood pro\u00adtec\u00adtion and not pri\u00admar\u00adi\u00adly nature con\u00adser\u00adva\u00adtion. But the dry pold\u00aders are also of great impor\u00adtance for nature con\u00adser\u00adva\u00adtion as alter\u00adna\u00adtive areas for plants and ani\u00admals that have adapt\u00aded as cul\u00adtur\u00adal suc\u00adces\u00adsors to exten\u00adsive cul\u00adti\u00adva\u00adtion by humans. Such alter\u00adna\u00adtive areas are need\u00aded because the nation\u00adal park con\u00adcept pro\u00advides for 50 per\u00adcent of the area to be tak\u00aden out of use, which is there\u00adfore unsuit\u00adable for cer\u00adtain cul\u00adtur\u00adal followers.\n<\/div><\/div><\/i><\/span>Map of the pold\u00aders in the Low\u00ader Oder Val\u00adley Nation\u00adal Park<\/span><\/a><\/div>\u00d7<\/button>The polder system in the Lower Oder Valley after the regulation work at the beginning of the 20th century<\/h3><\/div>\nMap of the pold\u00aders in the Low\u00ader Oder Val\u00adley Nation\u00adal Park<\/p><\/div>\n<\/div>
