On April 7th, 2025 our team completed their first of many river walkovers to map the existence barriers fragmenting river connectivity.

We went out to look for barriers to map the Verdugo-Oitaven basin, in Pontevedra, Galicia (Spain). We walked a small 1st Strahler order stream (regueira dos muíños near Acevedo) where they identified a couple of culverts and noted the widespread lateral fragmentation caused by stony bank walls and revetments.



Following the small river downstream, we reached its confluence with the main river of quite greater discharge: the river Verdugo. Most of its banks also showed abundance of bank walls and revetments, both old and new, indicating a long history of anthropogenic fragmentation of lateral connectivity.



Many more to come…
