Grazing Heather Moorland

Vinny O’B Smith, Countryside Management Delivery Branch, DARD

Heather moorland is an important habitat, which provides a valuable grazing resource and also supports a wide variety of wildlife.
In winter sheep will change their grazing preference to heather as grass growth and availability declines. In agri-environment schemes no grazing of heather moorland is permitted from 1 November to 28/29 February. This is to reduce damage caused by winter grazing and to promote heather recovery.
Almost 55,000 ha of heather moorland is currently being positively managed by farmers through agri-environment schemes. Positive management includes  following an agreed grazing plan for all areas of heather moorland on the farm.
Grazing plans vary according to stock type and the category of heather moorland present on the farm, which may be dry heath, wet heath or blanket bog. If you are an agri-environment scheme participant you will find heather moorland grazing information specific to your farm in your scheme booklet and details will be listed on your scheme map.
Table 1 shows grazing dates for agri-environment scheme participants.

Wet Heath Sheep only 1 Mar to 31 Oct 0.25
Cattle only 1 Jun to 31 Aug 0.20

1 Sep to 31 Oct (sheep only) 0.25
Blanket Bog Sheep only 1 Mar to 31 Oct 0.075
Having the correct grazing balance in place is essential. Grazing intensively reduces heather content and increases the presence of tussock and mat grasses, which are of less grazing value. Whereas grazing very extensively can result in heather becoming tall and woody, with reduced grazing value for livestock and wildlife alike.
