The US Forest Service, The Nature Conservancy, and The World Fish Migration Foundation invite you to save the date and register for an exciting upcoming webinar entitled: Removing “Road Dams” in Europe? taking place on 19th January, 2022 from 15:00-18:00 CET. 

This is a free, international webinar that will highlight the need and opportunities to improve road and stream crossings to enhance the biodiversity of rivers across Europe! 

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

Confirmed speakers include:

  • Carlos García de Leaniz of Swansea University, Wales | Topic: An overview of Europe’s current policies and research needs
  • Bob Gubernick of the US Forest Service, USA | Topic: Stream simulation principles and applications in the USA
  • Sofia Perä, County Administrative Board of Norrbotten, Sweden | Topic: Culverts in Sweden and lessons from the LIFE REMIBAR project
  • Joshua Royte, Nature Conservancy Maine, USA | Topic: Opening up headwaters in Maine, USA
  • Nat Gillespie, US Forest Service, USA | Topic: What is the problem with culverts and road-crossings?

The full program, which includes speakers from both Europe and the USA, will be released in the coming month. Make sure to register so you don’t miss any important updates! We hope to see you there. 

Sponsor deals for companies: The webinar is additionally open for sponsorship from 6 companies. At this point, we have 5 spots left. For 1,000 euros, companies can show a 30-second commercial video about how they are involved in culvert replacement or the removal of culverts. The logo of sponsors will be shown on Eventbrite, announcement, and conference program. Please contact for more information about sponsorships. 

Last Tuesday, Ewa Orlikowska, PhD-student at Swedish University of Agricultural Sciences, gave a seminar titled “Gaps in ecological research on the world’s largest internationally coordinated network of protected areas: A review of Natura 2000” at Karlstad University. The seminar is available online upon request. Send an e-mail to to get access to the seminar.

The papers Gaps in ecological research on the world’s largest internationally coordinated network of protected areas: A review of Natura 2000 and Contribution of social science to large scale biodiversity conservation: A review of research about the Natura 2000 network, both by Orlikowska et al. relate to the seminar content.

Last week, Theodore Castro-Santos from Conte Anadromous Fish Research Center (USGS) gave a webinar titled “Safe, Timely, and Effective: toward a unified metric of passage performance” on the World Fish Migration Platform. The webinar was also streamed live at the Congress of the Iberian Society of Ichthyology, The webinar is now available online (after free registration) at the World Fish Migration Platform here (follow the link at the bottom of the page).


Webinar: Small Scale Dam Removals

Posted by Daniel Nyqvist | Events

Joint Committee on Fisheries Engineering and Science (American Society of Civil Engineers Environmental Water and Resources Institute & the American Fisheries Society Bioengineering Section) organiserar ett Webinar om utrivningar av mindre dammar. Webinaret ges av Michael Chelminski från Stantec Consulting Services Inc. och har titeln “Why Did the Dam Cross the River? Getting to the Other Side of Small Dam Removal.”

Så här introducerar organisatörerna föredraget:”This 60-minute presentation addresses opportunities, constraints, and approaches to small dam removal, including the scope and scale of studies for dam removal design and permitting and differences between large and small dam removals. This topic is important because of the number of small dams, the cumulative impact of these dams on natural resources, and the potential to build on the success of larger dam removal projects by removing small dams in the large-project watershed. In recognition of limited funding for dam removal projects, this presentation also identifies and addresses the need to scope design and permitting studies for small dam removal projects based on the potential impacts — or lack therefore — of dam failure.”

Webinaret ges den 22 Juli, klockan 17:00 svensk tid. Anmäl er genom att maila Abigail Archer på och se mer information här.

Webinar: Dam removal – online

Posted by Daniel Nyqvist | Nyheter

I mars arrangerade World Fish Migration Platform ett online-föredrag av Laura Wildman om Dam removal. Föredraget går nu att se eller ladda ner i efterhand här eller genom att klicka på bilden nedan.


Kvaliteten är sådär under inspelningens första minuter, men när föredraget väl sätter igång (efter ca: 8min) så funkar allt bra.

Webinar: Dam removal

Posted by Daniel Nyqvist | Events

World Fish Migration Platform arrangerar ett online-föredrag om Dam removal. De skriver: “We are very happy to announce that the World Fish Passage Platform is preparing a series of webinars for 2015. The first webinar will be an introduction about Dam Removal, its key issues and lessons learned. The webinar will be presented by one of the mayor experts in this field, Ms. Laura Wildman of Princeton Hydro, LLC. (Connecticut, USA). 

Dams are removed for a wide variety of reasons including issues relating to economics, dam safety, liability, and environmental concerns. However, even when a dam has outlived its initially intended use and dam removal is proposed there still may be numerous challenges that need to be addressed prior to removing the dam.

This webinar will review the key deciding factors that need to be analyzed when making a decision to remove a dam including the environmental benefits and impacts; channel stability and sedimentation concerns; community apprehensions regarding aesthetic, historic and recreational values; and issues relating to the scale of the project, its current uses, project constructability, funding, impacts to infrastructure, ownership, sensitive species and regulated resources. The lessons learned from over 40 dam removal projects in the U.S., both proposed and completed, will be discussed to highlight these key issues and deciding factors.

This webinar will be on the 25th of March of 2015 (16:00 European Central Time; 10:00 USA Eastern Time). It will be one hour long and FREE of cost. There will only be 100 spots, so make sure you register as soon as possible to get in!
