The Stroud Valleys Project (SVP) says it follows a successful trial with a group of people with macular disease.

They were taken on a nature walk along a stretch of the Stroudwater canal, to study its flora and fauna.

The SVP is planning a six-week wildlife course this spring and other events like a bat walk, swan feed and guided tour of Westonbirt Arboretum.

'Other senses'

Deb Coleman, community biodiversity projects officer, said: "It's using other senses, the bat walk uses detectors so they can pick up the sounds.

"Some of what we're doing may be to do with geology and archaeology - learning about the area and its wildlife."

Organisers are still trying to assess the demand for the course and are asking anyone interested to contact them.
