The Northern Ireland Landscape Character Assessment subdivided the countryside into 130 Landscape Character Areas (LCAs), each based upon local patterns of geology, landform, land use, cultural and ecological features. For each LCA, the key characteristics were described and an analysis of landscape condition and its sensitivity to change was made. Detailed descriptions of these landscapes are provided in the Northern Ireland Environment Agency's (NIEA) series of Landscape Character Assessment Reports (July 1999); the descriptions are also available on the NIEA website: https://www.daera-ni.gov.uk/northern-ireland-environment-agency
