Removing ‘road’ dams in Europe – Webinar

By November 18, 2021January 17th, 2022One Comment

The World Fish Migration Foundation, 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! 


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


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!  

We invite river and restoration practitioners, policy makers, researchers, and students, as well as road planning, maintenance, design and construction experts to join! The event builds on experience from projects across the US and Europe. 

This Dam Removal Europe webinar is made possible by the World Fish Migration Foundation, US Forest Service, The Nature Conservancy, Wetlands International, Oregon RFID, Biomark, and The Dutch Postcode Lottery.
