Seagrass Secret: Island Reserve Holds Hidden Marine Life

A pioneering underwater survey is set to map the seagrass habitats surrounding Brownsea Island, a significant nature reserve located in Poole Harbour, Dorset. This initiative marks the first comprehensive effort to chart these critical marine environments.

Initial findings have already indicated a rich abundance of seagrass, which serves as a vital sanctuary for a variety of wildlife, including vulnerable seahorse species. The detailed underwater exploration is scheduled to be conducted by oceanography experts from the University of Southampton.

This important project, instigated by National Trust ranger Sophie Giles, is anticipated to take place in the first half of 2026. Mapping these seagrass beds is deemed essential for implementing effective conservation strategies and ensuring their long-term protection.
