Project summary

Edit project overview to modify the project summary.

The Amerongse Bovenpolder project aims to improve biodiversity, function as a green corridor, maintain and improve landscape, and to improve conditions for recreation and cultural-historical values. The polder has been previously used as a landfill, for sand excavation, and for tabacco cultivation.

Rijkswaterstaat and DLG Government Service for Land and Water Management created a 45 acre seepage swamp to improve conditions for the variety of flora and fauna in the Bovenpolder. The marsh is fed by clean groundwater (= seepage) from the Utrecht Heuvelrug (hill ridge). Seepage swamp is an ideal habitat for plants that need (iron rich) groundwater such as water gillyflower, mare's-tail and sedge species. In the coming years, an old river channel will be dug outin the Bovenpolder and semi-wild horses and cattle graze the area. These measures will make the Bovenpolder suitable habitats for amphibians, small mammals, insects and marsh birds such as night heron and black stork. Ecological connections between the Utrechtse Heuvelrug the Bovenpolder will also be restored in the future, by the constructing a wildlife crossing allowing birds and mammals to pass unhindered from areas high-up to low down by the river, and vice versa. The development of the Amerongse Bovenpolder is a collaboration of the Province of Utrecht, DLG Government Service for Land and Water Management, the Ministry of Agriculture, the municipality of Amerongen, Hoogheemraadschap (water board)The Stichtse Rijnlanden and Rijkswaterstaat.
