Why river fragmentation
can't wait

Freshwater ecosystems are among the most threatened in the world, and the main driver of their degradation is fragmentation. The river network of the Czech Republic is one of the most fragmented in Europe. Transverse barriers — weirs, dams, sluices — interrupt the natural migration corridors of fish and disrupt ecological processes along the entire length of watercourses and into the adjacent floodplains.

This workshop closes sub-goal 7.2 of the Centrum Voda — Water as an Environment for Life project and delivers results where they can make a real difference: into the hands of river basin managers, nature conservation authorities, and the expert and general public.

It is not only a presentation — it is an active discussion of concrete solutions and their implementation in practice.

What the workshop will cover

The workshop summarises the results of sub-goal 7.2 — River Network Fragmentation of the Centrum Voda project. The aim of 7.2 is to understand the anthropogenic pressure of fragmentation on aquatic ecosystems and to offer tools to address it.

The project's main outputs focus on:

  • Updating the Concept for Restoring Passability of the river network
  • A methodological framework for monitoring lateral and downstream fish migration
  • Assessing the impact of river network fragmentation in the Czech Republic, including the effectiveness of fish passes

By taking part in the workshop, you will have the opportunity to comment on the proposed approaches and contribute to the effective restoration of river connectivity. Interim results can be viewed on the Centrum Voda website.
