Native title of the NBS intervention
Solent Seagrass Project
Short description of the intervention
This project is studying seagrass to learn more about the distribution and health of seagrass in the waters of the Solent. By learning about where seagrass exists it can be better protected. The Wildlife Trust have been visiting local seagrass sites including the harbour in Portsmouth (1). Measures that can be employed to help protect Zostera beds include Boat mooring management - a program of awareness to relieve pressure on seagrass in areas of high boating activity, such as the Solent (3) and restoration through seeding or transplanting seagrass and Improving habitat conditions to encourage natural regeneration and colonisation (3).

Present stage of the intervention
Goals of the intervention
1. Undertake survey work to improve knowledge of the distribution, extent, health and biodiversity of seagrass beds in the Solent (3)
2. Raise awareness of seagrass beds amongst stakeholders and the public
3. Produce a seagrass inventory for Hampshire and Isle of Wight.
4. Encourage reporting of seagrass occurrence in the Solent by the public, as a means of raising awareness and locating other possible seagrass sites.
5. Exploring several seagrass management options such as:
- Boat mooring management - program of awareness to relieve pressure on seagrass in areas of high boating activity, such as the Solent area (3)
- Fishing activity management
- Waste management for boats
- restoration by seeding, transplanting seagrass shoots, Improving habitat conditions to encourage natural regeneration and colonisation.
