Natural Flood Management Interventions on Crompton Moor

The works currently being undertaken are part of an initiative to introduce Natural Flood Management measures to upland areas to help reduce the risk of flooding to communities downstream.

The measures being installed in the adjacent watercourse, the Old Brook, are called engineered log jams or leaky dams. The log jams are designed to hold water back during and following rainfall events and release it slowly so that we can control the rate of flow downstream in the River Beal.  This can help to reduce the risk of flooding to communities adjacent to the river Beal, such as Crompton, New Hey and Milnrow.

Allowing the water to back up will not only provide flood management benefits but it will also create new habitat space for plants, insects and amphibians and will help to support the establishment of sphagnum moss which is key to the restoration of the peatland bog.

The leaky dams are being constructed from trees being felled from the adjacent woodland plantation. The trees being removed will help to allow more light into the woodland which will encourage a greater diversity of ground floor shrubs and plants to establish which is good for wildlife.  Permission has been granted from both Oldham Council and the Forestry Commission to remove these trees.  Working with Friends of Crompton Moor, City of Trees have established which trees are most suitable for felling to ensure that protected wildlife species are not disturbed.

A new look to things

Over the coming months, the Friends of Crompton Moor site will be undergoing a few changes.

We’d like to revamp things a bit; with a new look, and to make the site more relevant to what FCM is today – the site as it is reflects what we were several years ago, since when we have evolved considerably in terms of focus, direction and our approach to caring for the moor.

Meanwhile, if you need any info about FCM, just explore the site as it is, and as ever, please get in touch if you want to find out how you can come along and join us in our work on the moor.

Crompton Moor rises above the town of Shaw, near Oldham

It is unique locally in its diversity of wildlife, and has been designated a Site of Biological Importance (SBI) by the Greater Manchester Ecology Unit.

There is grassland, woodland, dry heath, wet bog and heather, and an impressive waterfall which flows into Pingot Quarry.

Friends of Crompton Moor hold regular events, activities and tasks involving the maintenance and enhancement of this rich environment.

If you enjoy the outdoors, and have an interest in wildlife, why not join us at one of our regular meetings . . .
