Hundreds of trees have been planted as part of the first project to trial natural flood management techniques to help improve protection for the people of Leeds and living near the River Aire.
The pilot site on a working farm at Eshton Beck, Gargrave now has 650 new trees planted by staff and trainees from Yorkshire Wildlife Trust and volunteers.
Yorkshire Wildlife Trust has also worked on three further pilots on the same site, with a whole host of volunteers from the Environment Agency, Leeds City Council, Yorkshire Water, The Conservation Volunteers, Craven Conservation Group and SCAPA, a firm based in Gargrave. They were also helped by students and staff from Leeds University and NVQ trainees from Craven College. The flood alleviation work involved building 66 log and brash leaky dams, planting a further 850 trees, undertaking 0.5ha of woodland management, building a 20m-long log revetment – using timber to prevent bank erosion and installing 200m of fenceline and a water gate to protect the new trees from nearby grazing stock.
The aim is to see how natural techniques can slow the flow of water and reduce the risk of flooding downstream. The trees include dogwood, guelder rose, downy birch, alder, and willow which will be planted along with hedgerows of hawthorn, blackthorn and hazel. Other measures carried out at part of the project include fencing works, creating leaky barriers and woody dams and stabilising river banks.
This £500,000 pilot programme, funded by Leeds City Council, uses natural methods to slow the flow of water from upstream in the catchment. This includes land management to reduce water run-off, woodland creation to increase tree canopy cover and river and flood plain restoration so that the landscape can hold more water in times of flood.
These pilot sites will allow the team to monitor and research the techniques used to gather evidence and increase their understanding of the benefits they provide for reducing flood risk. The pilot programme will also be used by the Environment Agency and Leeds City Council to develop a co-design approach to working with landowners, tenants, local authorities and other key partners such as the Aire Rivers Trust and the White Rose Forest. This will help to then develop future plans for the catchment.
The second phase of Leeds Flood Alleviation Scheme has a strong focus on natural flood management, with proposals to create new woodland areas which would more than double canopy coverage in the River Aire catchment. It focuses on protecting the Kirkstall corridor, which was badly hit by the 2015 Christmas floods, and areas beyond the city boundary to further reduce the possibility of the river flooding in Leeds.
