Upland vegetation survey of Bwlch Corog, Ceredigion (2005)

  • English

  • All

This dataset comprises of the results from vegetation survey work carried out at Bwlch Corog. Bwlch Corog is located between two Sites of Special Scientific Interest (SSSIs): Pengarreg−gopa a Moel Hyrddod SSSI and Pencreigiau'r Llan SSSI, which are notified for their blanket mire, dry and wet heath vegetation. The survey area can be divided into three main sub−areas: the enclosed fields of Pemprys and Cefn Coch separated by the more upland area of Bwlch Corog. The vegetation of this central area can be regarded as the most semi−natural and the principal vegetation types are M25 Molinia−Potentilla mire, M17 Scirpus−Eriophorum blanket mire, M15 Scirpus− Erica wet heath, H12 Calluna− Vaccinium heath, M6 Carex−Sphagnum mire U4 Festuca− Agrostis−Galium grassland, U5 Nardus−Galium grassland and U6 Juncus−Festuca grassland. There are large expanses of species−poor Molinia−dominated vegetation pointing to a prior history of frequent burning and heavy grazing which probably ceased when the adjacent forestry was planted.

Lineage

The site covers 427.5 ha and rises from 140m to 388m OD on Bwlch Corog itself. The southern part of the site is currently grazed by sheep at a low grazing pressure, while the northern part of the site has been recently cattle grazed. Homogeneous stands of heath, mire, grassland and associated vegetation were identified, sampled and mapped, using the National Vegetation Classification (NVC) as the basis for community definition. Additional forms of vegetation were recognised when floristic composition differed from the descriptions given in the NVC. Field survey work, including mapping and sampling, took 6 person days. Due to shortage of time, quadrats were only recorded in the more extensive and ecologically more interesting vegetation types. Accurate identification of plants encountered during floristic recording was considered to be important, and particular care was taken to distinguish between closely allied species with distinct ecological preferences. Bryophytes and lichens of uncertain determination in the field were sampled and subjected to later microscopic identification.
