Stone and timber ‘leaky’ dams
In February 2021, with the help of local residents, the National Trust team began installing ‘leaky dams’ in Buckden Wood using natural flood management methods. Natural materials from the local area were used with the aim to reduce the impact of flooding on nearby communities including Irwell Vale, Strongstry, Chatterton and Ramsbottom, as well as improving habitats for local wildlife.
In total 22 ‘leaky dams’ have been installed along the brook that flows through the woodland into the River Irwell. They are called ‘leaky dams’ due to acting as natural interventions in slowing down the flow of water, rather than redirecting or stopping it altogether. Similar works have been carried out on our tenanted farmland in conjunction with other natural flood management techniques.
As part of the National Trust Volunteer Programme, regular maintenance of these dams is undertaken to ensure they continue to work effectively.
Peatland Restoration Project
Holcombe's moorland is a precious environment where over the years air pollution and the impact of the Industrial Revolution, as well as moorland fires, erosion, and overgrazing, have brought significant damage to the peat surface.
These pressures have caused the surface of the peat to dry out and harden. This, in turn, increases the likelihood of flooding downstream as the water flows over the hardened peat. The change in peat condition has led to a change in the plants that grow on the moor leading to a reduction in a suitable habitat for breeding moorland birds. The drying up of the peat has also reduced its ability to capture and store carbon from the atmosphere, and degraded moorland peat can lead to an increase in carbon dioxide and other greenhouse gases being emitted into the air.
Working alongside a number of partners, read more about the ongoing peatland restoration work we are carrying out to protect this precious environment.
