Phase 2 Lowland Grassland_Sites

This is a spatial dataset containing sets of survey site boundaries recorded during the Phase 2 Lowland Grassland Survey of Wales (1987-2004). The Phase 2 lowland Grassland Survey of Wales was a detailed survey of plant communities in semi-natural lowland grassland vegetation. The chief aims of the Phase 2 survey were to characterise the semi natural lowland grassland vegetation of Wales and to provide a systematic conservation assessment of the sites surveyed. Sites varied in size and complexity from small uniform hay-meadows of less than 1 ha to extensive wet-dry pasture systems covering. The survey was started by Nature Conservancy Council (NCC) and continued since 1991 by Countryside Council for Wales (CCW) and 2013 by Natural Resources Wales (NRW).

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 covers that extent on the ground.
