Over the last few years the high rainfall and snow falling nearer to spring time combined with a couple of poor years in the growing season and an increase in large groups walking the hills, have resulted with the Beacons beginning to erode once more.
In the past, walkers along with the weather had worn down some of the footpaths and the surrounding areas up to 2.5m deep. Due to a lack of funds, we had not been able to build these back up to the original height resulting in them being a catchment for snow and rain.
Walkers compact the deep snow turning it into ice which everybody avoids. This results in people spreading out to look for the shallowest snow to walk on leading to a new section of land being worn away. The increase in walkers causes this erosion to get deeper and wider with some areas having seen a soil loss of up to 10cm in one year. This occurs most winters.
Due to the erosion, we have to revegetate the area after every winter if we want to prevent further loss of soil. But I have noticed the damage from this recent winter is worse as more and more large groups climb to the summits and continue to spread out.
Throughout the spring the weather
remained cold which delayed our revegetation work by several weeks on all the major access routes, so we did not begin work until the end of May. With the help of a group from Pontypridd and London & Middlesex, these National Trust volunteers provided vital help on the path leading up to Corn Du from Storey Arms by digging ditches, breaking up the compacted ground and starting to spread grass seed and fertilizer to give the land some much needed nutrients.
At the end of June we will be airlifting over 100 tonnes of sandstone scalpings (small stone and dust) on to the Storey Arms to Corn Du path. This is the only stone we are permitted to use and we will be doing this because the scalpings airlifted 11 years ago have now all but eroded away.
Look out for the next blog from the access team where we will update you on the footpath work following the airlift.
