Phase 2 Lowland Grassland Vegetation

The purpose of this data capture was to characterise the semi-natural lowland grassland vegetation of Wales and to provide a systematic conservation assessment of the sites surveyed. This is a GIS dataset containing vegetation types recorded during the Phase 2 Lowland Grassland survey of Wales (1987 - 2004). A detailed survey of plant communities in semi-natural lowland grassland vegetation. Sites vary in size and complexity from small uniform hay-meadows of less than 1 ha to extensive wet-dry pasture systems covering over 100 ha. The survey was started by Nature Conservancy Council (NCC) and continued since 1991 by Countryside Council for Wales (CCW).

Metadata Language: English

Lineage: Surveyed all forms of semi-natural neutral, acidic and calcareous grassland in lowland Wales, as well as wetter Molinia (purple-moor grass) and Juncus (rush) pasture communities and associated soligenous mires. Community definition follows the National Vegetation Classification (NVC). At each site, homogeneous stands of vegetation were identified, sampled with 2 x 2 m quadrats and mapped onto Ordnance Survey base maps or aerial photographs at 1:5000 scale. The main limitation of the data is their age. Habitat composition may change over time due to successional trends and also through agricultural treatments or even planned developments. A record of a vegetation type in the data is therefore no guarantee that it is still extant on the ground.
