WTSWW’s marine monitoring work gathers evidence for critical datasets, used to strengthen the resilience of Wales’ network of protected marine sites and the protection of the marine species found within these sites. Long-term, uninterrupted datasets are particularly important to assess broad population trends, filling knowledge gaps, and informing decisions about use of the marine environment.

The Wildlife Trust of South and West Wales' 11 local groups carry out all manner of fundraising activities, evening talks and events, as well as recruiting new members, local publicity, nature reserve work parties and membership support.

Our local groups raise the profile of the Trust in their communities and have always been at the core of our Trust's work.
