Phase 2 Lowland Grassland Survey of Wales
A detailed survey of plant communities in semi-natural lowland grassland vegetation. Community definition follows the National Vegetation Classification (NVC). The survey was started by Nature Conservancy Council (NCC) and with Countryside Council for Wales (CCW) and is now managed by Natural Resources Wales. This dataset contains all the floristic quadrat data and site information from the Phase 2 Lowland Grassland Survey of Wales.
This dataset has all Wales coverage with sites varying 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 primary objective of the survey is to characterise and evaluate the vegetation cover of lowland grasslands in Wales to ensure the identification, protection and management of important grassland sites is appropriate.
Entire dataset has been extensively validated and verified. The main limitation of the data is their age - habitat composition may change over time due to successional trends, agricultural treatments or even planned developments. A record of a vegetation type in the digital data is, therefore, no guarantee that it is still extant on the ground.
Surveys were 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. The data was captured in Recorder 6 to keep the data in a more stable environment to secure it for future use, to enable data analysis and to ease the data exchange process. 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.
