Project summary

Edit project overview to modify the project summary.


The project aims to achieve some habitat restoration and demonstration sites to engage with land managers. The current status of the river Kent and its tributaries is “good to moderate”. The reasons for failure to achieve good status throughout are due to diffuse pollution.

Poor geomorphology is also an issue on the Kent. Many of the natural meanders have gone and been replaced by straight, featureless sections. The river has been dredged and much of the natural bed has been dug out and been piled up on the banks. As a consequence the gravel depth is shallow and area available to salmonids to breed has reduced. Bank-side trees and vegetation have been significantly reduced.

Prioritising the Rivers Sprint and Mint, the project is to work with farmers and landowners to: • Establish at least 1500 metres of riparian buffer strips established, up to 10 metres wide on demonstration sites. • Provide 2 demonstration sites, raise awareness of riparian issues locally amongst 4 communities / groups, and pave the way for more ambitious restoration in the river Kent catchment (in line with the Jacobs report). • Minimise erosion, sedimentation and diffuse pollution. • Address diffuse pollution, and move river condition towards good status

Community Involvement - Engagement activities will include public consultations, practical volunteering activities like beach cleans, and tree planting, and awareness-raising through media and face-to-face contact.
