Lineage

The sites selected included Rhosneiger, Llanbedrog Low water lagoon, Oyster Bank (Pwllheli), Glanllynnau, Sarn Badrig and Tremadog Bay, and West Angle Bay. - Rhosneigr: An algae specific species inventory was undertaken at rock pools at different levels across the shore. Viewpoint photography was used to illustrate the overall distribution of Ascophyllum nodosum and other fucoid seaweeds on the rocky shore area. A series of monitoring was also conducted on a population of Cystoseira tamariscifolia and other conspicuous species was undertaken, in an area colonised by Sargassum muticum by recording overall percentage cover. - Llanbedrog Low water lagoon: An algae specific species inventory was undertaken during a low spring tide. - The Oyster Bank (Pwllheli): A SCUBA diving survey was conducted for the Barbed Twig Weed (Anotrichium barbatum). An inventory of other species found at the site was made in situ and samples taken for laboratory examination. This survey was also used for a Phase 2 descriptive of the site. - Glanllynnau: SCUBA diving surveys were conducted in both sites to collect a species inventory of the sublittoral fringe and shallow subtidal area. - Sarn Badrig and Tremadog Bay: the work carried out related to quality control of ongoing long term monitoring of the subtidal algal communities. A total of 4 dives recording dives were undertaken and the cumulative number of species were recorded over a period of 1 hour for each dive. - West Angle Bay: An inventory of seaweeds was obtained from 7 habitats selected shore habitats.
