Derbyshire Wildlife Trust

The Derwent Living Forest.

Derby Knotweed supports the Derbyshire Wildlife Trust. The Trust leads the Derwent Living Forest, a nature restoration programme across the Derbyshire Derwent catchment.

Every job plants a tree.

Its vision is to create 30,000 hectares of connected wooded habitats and wetland by 2050, including woodland, hedgerows, orchards and parklands. We value that ambition for the landscape and rivers around us.

Common questions

Useful answers before you call.

Can you help if I’m buying or selling a property?

Yes. We can survey suspected Japanese knotweed and prepare a management plan to support a property transaction. Ask your solicitor or lender what documents and guarantee terms they require for your particular case.

How long does treatment take?

It depends on the extent of the growth and the chosen method. Treatment commonly takes more than one growing season, with follow up monitoring agreed in the plan.

Do you work near rivers and watercourses?

Yes. Water adjacent sites are a particular area of experience. We assess conditions and choose an appropriate method for each location.

Can you identify a plant from a photo?

Send a clear photo of the leaves, stems and wider patch. We offer an initial photo identification at no charge, though a site visit may still be needed for a formal survey.

Do you only work in Derbyshire?

No. We are based in Derbyshire and undertake work across the Midlands and further afield.
