Gelderland WP2

In the Ooijpolder-Groesbeek area, herb-rich grasslands have been developed on a number of sites. The area is located east of the city of Nijmegen, between the river Rhine, the German border and the hills (remnants of the ice age). The biodiversity situation and soil type are herbal grassland on clay and sandy soil, both farmland and dikes and is part of de ’Living Lab Ooijpolder.

Location

The plots are located in the Ooijpolder-Groesbeek area (20-30 hectare).

Work planned/methods tested

Vegetation surveys (Braun-Blanquet) of selected plots in spring/early summer before the first mowing, in consultation with the participants and project management.

Surveys and additional photos and checks are planned in 2026. In 2027 recordings, surveys photos and checks will take place.

Aim of work

Inventory of the vegetation composition of new and previously established herb-rich grasslands in relation to soil, management and restoration practices. The success of different seed mixtures (establishment, maintenance of herbs) will also be tested.

Status right now

We will make use of the many plots in the area established in different time frames and with different purposes, from nature management to agricultural use. From vegetation surveys we get a complete picture of botanical restoration in relation to sowing and management, including development of the grasslands over time. Surveys will take place in spring / early summer in 2026.
