Map of River Habitat Survey sites

The map displays all existing 24,000+ sites in Great Britain. Because of the high number of points the sites will only be displayed above a certain zoom level. To view points on a river, locate the river at high scale, then zoom in closer until RHS points appear.
Click on individual RHS sites to get further information. You can also locate a place/river by using the search box below.

Last time RHS data updated: April 2012.
