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.

Mae Ymddiriedolaeth Natur De a Gorllewin Cymru yn trefnu cystadleuaeth farddoniaeth i ddathlu Diwrnod Barddoniaeth y Byd (21ain o Fawrth). Rydyn ni eisiau darllen popeth am yr hyn y mae natur yn ei olygu i chi, eich profiadau gyda natur, a pham mae natur yn bwysig. Mae croeso i geisiadau yn y Gymraeg ac yn Saesneg. Cyflwynwch eich cais i gael cyfle i ennill llyfr newydd Dan Rouse, 'The Children's Book of Birdwatching', yn ogystal â detholiad o lyfrau plant ysbrydoledig eraill. Bydd y gerdd fuddugol yn cael ei chyhoeddi ar ein gwefan ni, yn ogystal â chael sylw yn ein e-gylchlythyr misol, ac ar gyfryngau cymdeithasol.
