Connectivity is defined here as the exchange of sufficient organisms via dispersal and movement to sustain populations. Countryside Council for Wales (CCW) contracted Marine Ecological Solutions Ltd. (Marine EcoSol) to undertake the first stages of analysis, primarily to review species that may be vulnerable to low connectivity, or fragmentation, in Welsh waters. The vulnerability to connectivity project (presented in the current report) aimed to identify marine invertebrates, macroalgae, plants and small territorial fish which are theoretically vulnerable to low connectivity and fragmentation, and flag those that might need to be carefully considered when managing the marine environment around Wales. This dataset contains the results of the 'vulnerability to connectivity project', a five staged review of existing information which highlighted species that may be vulnerable to poor connectivity, or fragmentation in Welsh Waters based on information easily available in 2009. Connectivity is now generally recognised as an important criterion in the design of networks of Marine Protected Areas. Historical data was reviewed up to November 2008, with the earliest data point recorded in 1960.

Species' vulnerability was assessed based on their biological characteristics and was approached in four stages: - A review of information available for each species (from BIOTIC URL and the scientific literature) - Development of a method of scoring many species' theoretical 'intrinsic', or biological connectivity - Assessment of each species' specific habitat preference and the availability of this habitat in Wales - Assessment of species' perceived sensitivity to anthropogenic impacts and environmental change. Confidence in data is high however when interpreting the results, the assumptions made by the methods must be considered. Another consideration is the difficulty in identifying the species of interest; some species may be under-recorded due to mis-identifications or lack of observations. In addition, it is extremely important to remember that this project did not assess all benthic species found in Welsh waters but only those for which sufficient data was available.
