Phase 2 Lowland Grassland Mosaic Polygons

This is a spatial dataset of grassland mosaic polygons. These polygons are a gridsquares, coloured in chequerboard fasion according to Vegetation_type, for display purposes only. The records where collected during the Phase 2 Lowland Grassland Survey of Wales ( 1987 - 2004 ). Digitising this datasets allowed the detailed survey of plant communities in semi-natural lowland grassland vegetation to be accessible more widely. The purpose of this data capture was to characterise the semi-natural lowland grassland vegetation of Wales, and provide a systematic conservation assessment of the sites surveyed. 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). CCW now forms part of Natural Resources Wales (NRW). The main limitation of the data are the age of records. 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.

Lineage

The records are from surveys conducted on 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.
