British NVC community OV24 (Urtica dioica - Galium aparine community) is one of the open habitat communities in the British National Vegetation Classification system. It is one of four tall-herb weed communities.
This community occurs widely throughout lowland Britain and, if conditions are suitable, is also found in the upland fringes.
There are two subcommunities.

Distribution
This community occurs widely throughout lowland Britain. Under suitable conditions, it is also found in the upland fringes.
