“With every one of the 6 million visitors to the Peak District moors each year a small piece is removed on their soles”
Over the decades the loss of peat has created scars in the landscape along popular paths and the situation has been made worse by the action of water washing away the loosened soil. But less obvious is the effect to wildlife. As walkers skirt around the edges of eroded and boggy areas, paths widen, plants become trampled and the birds that nest on the ground, often close to paths, are disturbed. Birds frightened from their nest leave eggs or young vulnerable to prey, the cold and even the risk of trampling.
It is therefore essential that appropriate remedial work is carried out. Read on for technical drawings and case studies of the techniques employed by the Moors for the Future Partnership to restore our moorland paths.
The use of aggregate is confined to paths that are less than 1:10 gradient (i.e. for every 10 metres length of footpath, the vertical rise is no greater than 1 metre). Therefore aggregate has been used to good effect on all of the 6 easy access paths we have been responsible for upgrading since 2003.

This technique literally involves turning the path upside down using a large excavator. A ditch is dug and the spoil removed is used to create the new surface of the path. This technique is relatively cheap, working out at about £15-20/m2.

This technique involves interlocking large stones, with their flattest side up to create small irregular steps that blend into the landscape. Due to its cost (approximately £100 per metre), this approach is only employed where the gradient is too steep for the other methods (i.e. those above 1:4 (25%)).

The construction of Bridleways requires a slightly different approach with consideration of the needs of a horse and rider being taken into account. Paths need to be wider and less steep and steps should be reduced or avoided if possible. However, ramps should still be stepped in order to reduce the danger from slipping when icy. All of the techniques can be used, although flag paths should be used with caution.
The main users of upland bridleways will be mountain bike riders, legally they can use any bridleway, however bridleways have to be constructed so that they are suitable for use by horses rather than mountain bikes.
Bridleways will be more expensive to install than footpaths for the various techniques. The images to the right shows bridleway works at Cut Gate.

Once the path has been tackled, all that’s left is to tidy it up with a bit of housekeeping and make it blend into its surroundings. This involves landscaping, revegetating and stabilising the areas adjacent to the path.
