Northumbria Mammal Group was set up in 1997 by staff members from the Natural History Society of Northumbria (NHSN), Northumberland Wildlife Trust and Durham Wildlife Trust. Tees Valley Wildlife Trust joined a few years later.

The Group studies mammals in the area extending from the Scottish Borders in the north to the southern boundary of the Tees Valley and North Yorkshire, and from the North Sea coast to the Cumbrian border in the west.

While we are an independent group, our main objectives include supporting and working in close association with NHSN and the three NE Wildlife Trusts, raising awareness among local people of Northumbria’s native mammal species and their habitats, and doing what we can to protect them. To find out about our objectives and constitution click here. To view our privacy policy, see here.

In the What’s On section on this page you can see forthcoming mammal talks, field trips and activities, most of them organised by the Northumbria Mammal Group. All our members are very welcome to come along to these friendly events, whether you are a beginner or an expert. As well as mammals we do also see other wildlife and local flora.
