A wild and remote area of blanket bog on the Northumberland-Cumbria border, alive in spring to the haunting cries of the curlew.

A disused limestone quarry site, with probably the best exposure of Acre limestone in the county, with diverse habitats favoured by birds, amphibians and invertebrates.

A former quarry site, featuring woodland, scrub and grassland, with both geological and historical interest.

An area of beautiful open moorland featuring a mosaic of habitats attracting a wide array of interesting flora and fauna.

A sessile oak woodland, with some interesting flora including wood anemone and woodland birds such as wood warbler, tawny owl and woodcock.

One of the best 'calaminarian' (heavy metal) grasslands in the area providing perfect conditions for interesting flora such as dune helleborine.
