Väärin rakennetut tierummut voivat olla vaellusesteitä.
Ne voidaan kuitenkin kunnostaa ja avata vaellustiet kaloille ja muille vesieliöille.

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!
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!
