Phase 2 Lowland Heathland Survey of Wales

National Vegetation Classification (NVC) is the basis used for the selection of Sites of Special Scientific Interest (SSSI) and is used to define Annex 1 habitats for the selection of Special Areas of Conservation (SAC) under the Habitats Directive (EU Directive 92/43). This project comprises of detailed data related to the Phase 2 plant community survey for Lowland Heath across Wales. The project covers dry and maritime heath covered by the heathland section of the NVC and wet heath covered by the section of the NVC. Two non-NVC communities the calcareous grass and heath, and shingle heath are also described. This project had three main purposes: - To provide an overview of the Welsh lowland heathland resource allowing local conservation programs particularly local Biodiversity Action Plans (BAP) partnerships, to assess and interpret their resource in a Welsh context. - To identify heathland types which are underrepresented in the SSSIs series. - To identified gaps in knowledge and highlight areas for further study.

Metadata Language: English

Lineage: A total of 13 surveys were carried out: Anglesey (1994), West Gwynedd (1993), Gwynedd and Anglesey (1994), Pembrokeshire (1995, 1996, 1997), Rivers Ystwyth and Rheidiol, Ceredigion (1995), Gower Commons (1997), Gower, Bridgend, Vale of Glamorgan, Conwy (1998), Powys (1999), Brecknock and Carmarthenshire (2000), Ceredigion (2001) and Gower (2001). The total area of heath surveyed is approximately 4714 ha which is 35% of the total area of lowland and coastal (maritime) heathland recorded in the phase 1 habitats survey of Wales (1979- 1997). This was one of a series of major Phase 2 habitat surveys, including Countryside Council for Wales (CCW) in-house and commissioned surveys covering woodland, lowland grassland, saltmarsh and lowland peatland. The paper maps in the reports are of better quality than the GIS layer and therefore should be referred to as a more accurate source of information. Age of the data is also a limitation as habitat composition may change over time, a record of a vegetation type in the data is therefore no guarantee that it is still extant on the ground. Utilised standard Phase 2 survey methodology. Vegetation mapping and community definition followed the National Vegetation Classification (NVC). The dataset has been extensively validated and verified however problems were encountered when mapping in field which may have resulted in errors, digitisation was of poor quality and there were occasional problems with identifying community type. The species data has been digitised and entered into Recorder 6.

Specification

[A] Each survey has a corresponding paper report. [B] All Wales species and community data are held in a paradox database which is currently being transferred to Recorder 6. This data is also available on the NBN Gateway. See Resource Locator. [C] Vegetation polygons from all surveys have been combined into an All Wales collated MapInfo table. [D] Excel spreadsheets- some original survey data collated in excel spreadsheets however not clear which survey the data comes from and records are incomplete.
