Surveying the Gully Blocking

The survey team has suddenly gone from being a regular group of 4 volunteers to about 12 volunteer each week. Amazing! This means that so much more of the work that has taken place around the estate can be monitored for progress.

As There are now so many people the group now splits up to tackle different areas. One of the groups have recently been studying the effects that the gully blocking has had. Gully blocking is done to prevent water from draining off the moors, and taking some of the peat with it. We want to keep the water on the moors to prevent the peat from drying out and encouraging more plants to grow and keep the peat stable.

The gullies are blocked up with dams with the idea that water will build up behind the dams, with plants then growing in these areas which were previously bare.
This photo clearly shows the line of the gully with the water in it and being held back by the dams which are made with heather bales.
