Mortared wall: distribution in NI.
Mortared walls have a length of 0.2 km/km2 (2,188 km) in NI and occur mainly in the lowlands (0.2 km/km2, 1,975 km). The Mourne AONB (0.4 km/km2) and the Wider Countryside (0.2 km/km2) have the highest concentration.

Mortared wall: losses and gains 1991 - 1998.
Gains in Mortared walls were by building where previously there was no boundary or by replacing other types of field boundaries. Field Boundaries in the losses and gains table below are linked to their descriptors and NI data.
