Project summary

Edit project overview to modify the project summary.

There is the potential to realign and re-naturalise the river corridor running through the site. The bed and banks could be broken out and replaced with a natural channel with a vegetated buffer zone, marginal banks and in channel gravels. This would greatly improve the in channel processes and improve fish passage and habitat for invertebrates and foraging opportunities for birds and bats. The site would also be ideal for a riverside walk providing recreational and educational opportunities and proving access to nature which is currently missing in this area.
