The Burren, in County Clare is a region of outstanding historical and geological significance, as well as one of breathtaking beauty. The bare limestone surfaces are fretted with hollows and channels where acidic rainwater has selectively dissolved the rock.
Ecological diversity is one of the great attractions of the Burren with more than 700 different flowering plants and ferns having been recorded there. Thus, although the Burren represents only 1% of the land-mass of Ireland, 75% of the Irish native species are contained in the area.
Most of the area has been designated as a Special Area of Conservation under the EU Habitats Directive.
