Event description
International webinar highlighting the need and opportunities to improve road and stream crossings to improve Europe's river biodiversity

About this event

River fragmentation from constructed barriers poses one of the greatest threats to freshwater biodiversity and river ecosystem function. In Europe, there are an estimated 1.2 million barriers; over 200,000 of these are mapped culverts/road crossings.

Dams and weirs get much needed attention, but river fragmenting culverts and road crossings are more common and often overlooked. These structures have an outsized impact on critical headwater rivers and streams. It’s time to shed light on this critical issue!

The World Fish Migration Foundation, and The United States Forest Service, and The Nature Conservancy invite you to join us for a 3 hour, international webinar highlighting the need and opportunities to improve road and stream crossings to enhance the biodiversity of rivers across Europe!

This builds on experience from projects across the US and Europe.

We invite all river and restoration practitioners, policy makers, researchers, and students, as well as road planning, maintenance, design and construction experts to join!


When: January 19th, 2022 from 15:00-18:00 Central European Time (CET)


The program will include presentations from experts, live on-site interviews (including a tour inside a culvert), a Q&A session with the speakers, and more!

Carlos García de Leaniz of Swansea University, Wales | Topic: 200.000 culverts! An overview of Europe’s current status, policies and research needs regarding culverts and road crossings.
