Otterburn Ranges are set in some of the most unspoilt areas in the Northumberland National Park and lie between the valley of the River Rede and the Border Ridge. The landscape falls into the following areas:
- The Cheviots
- Coquet Valley
- Cottonshope Valley
- Moorland Plateau
- Redesdale
- Grasslees Valley
- Sandstone Hills
Otterburn Training Area also hosts many rare and protected habitats.
The Ranges contain most of the few species-rich upland hay meadows left in the National Park. These are an internationally rare habitat as 95% of these meadows have been lost across Europe over the last 50 years.
There are 260 hectares of blanket bogs which is an internationally rare habitat. They provide a habitat for the large heath butterfly which is mainly found within the UK in Scotland.
The most northerly upland heath in England is found here. It is important for ground nesting birds such as the black grouse, skylark and curlew.
There are also some of the cleanest and clearest rivers and burns in the country which are home to salmon and trout, as well as the otter and heron that feed on them.
