Why we need to manage the heather
It is important that we encourage the re-growth of young heather so that wildlife can thrive.The commoners who graze their sheep on the hill benefit from an increase in young heather as it is more digestible, it is more resilient to stock and to trampling damage than the old heather.
How we do it
The way the team manage the heather is by cutting and burning patches each year. By burning the heather these areas form breaks and gaps in the heather which help to provide fire breaks, and they also help the grouse.
The grouse need the heather to be patchy so that they can feed in the open and then run back into the heather to avoid predators.
Why we burn it
Burning is the most traditional and effective way to manage the heather. Underneath the older heather a moss layer starts to develop that actually limits the re-generation of the heather seed. Burning gets rid of the moss very effectively.
In some areas of the Long Mynd burning isn't appropriate, for example we don't burn in highly sensitive areas and around the pools.
When we do it
The team have a small window of opportunity to manage the heather and they have to try and burn around 20 hectares a year. It has to be done between mid-October and mid-April, although we stop burning by mid-March so that we don't encroach on the nesting season for the grouse.
The burning requires some specific weather conditions as well, we need a few dry days before burning so that the heather isn't damp, and on the day of burning we need ideally a North-Easterly wind, no more than 12 miles per hour.
A new purpose
In some cases we have chosen to cut the heather, this is because the old heather can go on to have other uses. In the past we have sold bailed heather to a filtration company in Holland, it has also been used to thatch a house in Clun and a summer house at Biddulph Grange Garden
We also use cut heather on our footpaths, in more sensitive areas where we don't want to put down stone, the heather absorbs the moisture stopping the paths from becoming muddy.
How we monitor re-growth
Each year the areas burnt are recorded on a map by our Ecologist, Andrew Perry. Over the years he monitors and assess the condition of the heather.
He also carries out wildlife surveys and bird counts with volunteers to see if the number and quantity of species living in and around the heather is increasing.
Stop Press: Heather update Sept 2019
You may have recently read about the health of our heather. The drought conditions of summer 2018, followed by a mild winter have combined to cause up to a 75% loss of Long Mynd heather. Much of the loss has been due to the heat, but heather beetle attack has also caused severe damage.
This means our management for the autumn and winter ahead will be based around burning large areas of this dead heather to encourage regeneration.
