Thames21 is working in partnership with Enfield Council to regenerate the former Royal hunting ground of Enfield Chase in the Salmon’s Brook catchment, part of the greater river Lea catchment. Restoring the tree cover will not only cut flood risk for businesses and homes downstream – it will boost the health of the Salmon’s Brook, too.
Rewilding a degraded landscape
The area was deforested more than two hundred years ago and is now mainly arable fields and some grazed pasture. Despite the best efforts and intentions, some conventional farming practices result in soil and nutrient erosion that flows into the local watercourses, threatening aquatic life. Drainage systems and straightened watercourses have encouraged water to move swiftly off the land and into the river, increasing flood risk to thousands of homes and businesses downstream.
Working with the local farmers, the Forestry Commission, and a woodland design consultant, areas have been identified where tree planting can slash flood risk and improve water quality.
A hydrological model calculating the angle of field slopes, soil type, and infiltration rate will guide targeted planting, starting this autumn, to deliver the greatest benefits. By combining areas of mixed density native tree planting with areas of natural regeneration, meadows, ponds, and swales, we aim to create a rich and diverse ecosystem.
Building London’s resilience
This huge new area of high quality green-blue space will benefit thousands of urban residents, as well as attracting and protecting wildlife. The diverse ecosystem, combined with natural flood management measures holding and slowing water flow further up the catchment, makes the landscape more resilient to drought and high rainfall events, which are increasing in frequency and severity due to climate change.
