Project summary

Edit project overview to modify the project summary.

The Tungelroyse beek is a meandering stream with a low flow velocity. It features several sand bars and overhanging banks. Sixty oak trunks were introduced into this stream.

Monitoring surveys and results

Edit project overview to modify the Monitoring survey and results.

The indroduction of large quantities of wood has increased the variation in substrate. Plant growth has been observed between the dead wood fragments, but there has been no positive effect on biodiversity. In some parts of the stream, there has been a stagnation of the flow and a silt accumulation due to the presence of watermills.
