Tansy beetle volunteers sought for Beningbrough Hall

Volunteers are being sought to help protect the habitat of an endangered beetle whose only UK home is on a river near York.

The bright green Tansy beetle, which can only be found in Britain on a 26-mile (41km) stretch of the River Ouse, needs vegetation unique to the area in order to survive.

The National Trust at Beningbrough Hall, North Yorkshire wants volunteers help with conservation work along the river.
