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. The survey locations and 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 datasets which were produced from this project have been extensively validated and verified. However, the main limitation of these datasets is their age. Habitat composition may change over time due to successional trends, agricultural treatments or even planned developments, which means that there is no guarantee that the information within these datasets is still representative on the ground today. However they do provide an important long-term catalogue of data which can be used to monitor changes to the grassland environments overtime. The dataset contributes to JNCC's UK Lowland Grassland Database, held by the Lowland Grassland Lead Co-ordination Network at NE in Peterborough. Where a grassland site has been resurveyed the most recent survey data is in the main Phase2 Grassland Survey datasets and the previous survey(s) have now been put into a folder called Archive [Historic] GIS layer files within this dataset include: Site boundary (Sites), Vegetation polygons (veg), Mosaic Table, Mosaic Polygons (Mospolys), Quadrats, Photos and Target Note (Notes, points, polygons). There is a DMS document explaining the GIS layers and data structure called P2 Grassland data structures in ArcGIS. Survey Reports are also available from NRW.

Roedd y prosiect hwn yn cynnwys arolwg manwl o gymunedau planhigion yn llystyfiant glaswelltir rhannol naturiol yr iseldir ledled Cymru. Diben casglu'r data hwn oedd nodi llystyfiant glaswelltir rhannol naturiol iseldir Cymru a darparu asesiad cadwraeth systematig o'r safleoedd a arolygwyd. Mae'r setiau data a gynhyrchwyd yn sgil y prosiect hwn wedi'u cadarnhau a'u dilysu'n drwyadl. Fodd bynnag, prif gyfyngiad y setiau data hyn yw eu hoedran. Gall cyfansoddiad cynefinoedd newid dros amser o ganlyniad i dueddiadau olynol, triniaethau amaethyddol neu hyd yn oed ddatblygiadau arfaethedig, sy'n golygu nad oes unrhyw sicrwydd bod y setiau data hyn yn parhau i gynrychioli'r hyn sydd ar y tir heddiw.

The areas surveyed included 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 a 1:5000 scale.
