Transitional Flanks

The impact of maintaining and restoring biodiversity at the flanks of the Heuvelrug stretches beyond these border areas. More nature at the flanks may also result in a more robust natural system in the national park itself: the total increase of the natural area provides for migration opportunities for flora and fauna. The flanks feature a varied biodiversity at the steep edges of the Heuvelrug and the floodplains of bordering rivers. This also includes biodiverse cultural-historical landscapes such as ash wood coppice systems.  

Intensive agriculture at the flanks impacts the environment by artificially changing groundwater levels, increased nitrogen deposition and cultivation of monocultures. A transition to more extensive agriculture is needed to reduce the pressure on the environment. Currently however, there is no clear, long-term perspective for farmers for developing alternative business models. UU research, strengthened by insights from local stakeholders could support the development of such a long-term perspective. In doing so it will contribute to the national goal of sustainable reductions in nitrogen emissions.

Because of deep groundwater levels, NPUH's flora is strongly dependent of precipitation for its water supply, while at the flanks of the national park seepage water rises to the surface and provides water for a large variety of species. Much is still unknown about the water system of the Utrechtse Heuvelrug, both at the flanks and in the national park itself. This concerns both the functioning of the natural water system in the park and the effects of water management strategies on nature. The partners of Stichting NPUH work together on a robust water system through the Blauwe Agenda. The Research & Education Hub Utrechtse Heuvelrug aims to provide the necessary scientific support for well-informed choices by the partners.
