  • The Development of Key Characteristics of Welsh Island Cultural Identity and Sustainable Tourism in Wales
    SCIENTIFIC CULTURE, Vol. 3, No 1, (2017), pp. 23-39 Copyright © 2017 SC Open Access. Printed in Greece. All Rights Reserved. DOI: 10.5281/zenodo.192842 THE DEVELOPMENT OF KEY CHARACTERISTICS OF WELSH ISLAND CULTURAL IDENTITY AND SUSTAINABLE TOURISM IN WALES Brychan Thomas, Simon Thomas and Lisa Powell Business School, University of South Wales Received: 24/10/2016 Accepted: 20/12/2016 Corresponding author: [email protected] ABSTRACT This paper considers the development of key characteristics of Welsh island culture and sustainable tourism in Wales. In recent years tourism has become a significant industry within the Principality of Wales and has been influenced by changing conditions and the need to attract visitors from the global market. To enable an analysis of the importance of Welsh island culture a number of research methods have been used, including consideration of secondary data, to assess the development of tourism, a case study analysis of a sample of Welsh islands, and an investigation of cultural tourism. The research has been undertaken in three distinct stages. The first stage assessed tourism in Wales and the role of cultural tourism and the islands off Wales. It draws primarily on existing research and secondary data sources. The second stage considered the role of Welsh island culture taking into consideration six case study islands (three with current populations and three mainly unpopulated) and their physical characteristics, cultural aspects and tourism. The third stage examined the nature and importance of island culture in terms of sustainable tourism in Wales. This has involved both internal (island) and external (national and international) influences.

  • Skokholm and Gateholm Coastal Waters Area Name
    Seascape Character Area Description Pembrokeshire Coast National Park Seascape Character Assessment No: 26 Seascape Character Skokholm and Gateholm coastal waters Area Name: Looking north to Skokholm (left) and St Ann's Head (right) from 2km SE of Skokholm, 3.5 km from shore Looking east to Skokholm (left) and Marloes peninsula Marloes Sands looking east Skokholm from the air (©Sid Howells) 26-1 Supplementary Planning Guidance: Seascape Character Assessment December 2013 Seascape Character Area Description Pembrokeshire Coast National Park Seascape Character Assessment Summary Description This area comprises the remote island of Skokholm, the coastal island of Gateholm, and the south west facing, rocky, indented eroding coast and western half of the Dale peninsula. The near vertical bedding of sandstone produces distinctive cliffs and rock formations with cliffs reaching around 50m high. The sea has strong tidal streams and races and is often subject to strong ocean swell particularly around St Ann’s Head. The Dale peninsula is an exposed plateau headland with both pasture and arable with rectilinear field pattern. Key Characteristics Skokholm is a wild, remote island with a flat top and sandstone cliffs. It is an important bird sanctuary and nature conservation site. Rough and jagged rock exposures and high sandstone cliffs, and rocky foreshores. The sea is highly disturbed and exposed with many rocks and other hazards, and strong tidal streams, races and eddies. The sea is heavily used by sailing cruising boats and day trippers, with some sea angling and diving and occasional wildlife trips to Skokholm. Due to the proximity to Milford Haven there is a lighthouse on Skokholm and at St Ann's Head.

  • Gateholm Island Seasearch 2006
    Gateholm Island Seasearch 2006 Gateholm Island is an old red sandstone island that forms the southeast corner of the Skomer Marine Nature Reserve. In July 2006 survey dives were organised by Kate Lock east of Gateholm, outside of the Reserve’s boundary. The surveys aim was to assess the suitability of the site as a location where research could be completed, as the collecting of samples is restricted by byelaw in the Reserve. The island’s waters and seabed lie within the Pembrokeshire Marine Special Area of Conservation. Marloes Peninsula Survey Skomer MNR boundary Skomer MNR boundary Area Reproduced from Admiralty Chart 2878 by permission of the Controller of Her Majesty’s Stationary Office and the UK Hydrographic Office (www.ukho.gov.uk) Not to be used for navigation In August a potato crisp bryozoan, Pentapora foliacea survey was completed at this site and at Watwick Point in the entrances of Milford Haven. Dr Joanne Porter, Aberystwyth University and Chiara Lombardi, a bryozoan specialist in Italy, led this research. At each site 20 colonies were measured and small samples collected. These measurements and samples will be analysed for growth and genetic studies, comparing to colonies collected in the Mediterranean. Kate Lock The survey area was between 18-24m bsl. Rocky areas ranged from tall outcrops up to 6m in height to large expanses of low- lying rocks and boulders 1-2m high. Between the rocks sand and gravel filled gullies were found between 1-2 m wide. In the Scott Tompsett southern and eastern edges of the reef the rock gave way to sand and pebbles with occasional small boulders.
