Border Mires is a group of around 60 peat bogs straddling Cumberland and Northumberland, in and around the Kielder Forest.  It is part of what was once the largest continuous tract of blanket bogs across northern England and is a Special Area of Conservation (SAC), designation number UK0012923.

The largest of these peat bogs are:

Butterburn Flow (447 hectares) Bell Crag Flow (150 hectares) Muckle Knowe (107 hectares) Blind Moss (104 hectares)

The remaining bogs have an average area of 32 hectares with the smallest, Muckle Gowany Knowe, only 1.8 hectares.

Eight of the bogs are a Ramsar site, ‘Irthinghead Mires’ (site 303, designated in 1985):

Butterburn Flow Coom Rigg Moss Felicia Moss Gowany Knowe Grains Heads Moss Haining Head Moss Hummel Knowe Moss The Wou

Many of the bogs sit within their own, or wider Sites of Special Scientific Interest (SSSI).  These SSSI sites are:
