Watercafé - Non-native river crayfish are on the rise

Yes. Tickets are free, but reservation is required.

Book via the registration link on the LUX programme page.

It is about non-native river crayfish in the Netherlands and what can be done.

The crayfish damage banks, water plants and native fauna.

They dig holes in banks, eat eggs and young fish and amphibians, and cut water plants.

This disturbs the ecological balance, lowers water quality and threatens vulnerable ecosystems.

It also makes it harder to meet the goals of the Kaderrichtlijn Water.

The water boards want the population brought back to a manageable level.

Henk de Vries of Vlinderstichting is senior project leader and works on good management of low peat marshes.

He speaks about effects on dragonflies, krabbenscheer and the groene glazenmaker.

Mariëlle van Riel is an aquatic ecologist at Stichting Bargerveen.

She has researched invasive species and an ecosystem approach to prevent invasive species dominance.

The approach focuses on restoring ecological processes in affected waters.

This can make ecosystems less vulnerable to invasions.

Yes. After the talks, the speakers talk with the room.

You can ask how to deal with invasive river crayfish.

You can ask which approach is preferred and what the water boards can do.
