Grouse chicks have specific habitat requirements |
As broods of young grouse begin to hatch out
across the hills, it’s a good moment to look back through some of the work the Heather
Trust has done on habitat management techniques for brood rearing over the past
few years.
Several keepers have found that traditional
grouse moor management is no longer viable in many areas, and there has been a
big push to discover new and innovative ways to produce grouse. Some of this
work has been undertaken by cutting heather, and this has opened up a whole new
side to heather management in which carefully customised habitat design can
work to reduce chick mortality and shift the moorland environment in favour of
young birds.
On Speyside, British Moorlands have worked
hard to keep grouse chicks safe from predators by cutting in long, narrow
strips across the hillside. This means that cover and security are never far
away, and young birds can quickly escape into thicker heather when predators
arrive. This theory also suggests that narrow cuts through mature heather can
“trap” insects which are blown on the wind, and informal studies have shown
that cuts provide just as much crucial insect life for chicks as traditional fires
burnt over larger areas.
Cutting through mature heather also allows
chicks to get access to mature blaeberry plants which are associated with a
rich diversity of caterpillars and grubs. This aligns with work undertaken by
the Welsh Wildlife Trust near Denbigh which has cut through areas of mature
heather to improve access to insects for young black grouse. 2018 has seen a cold,
dry spring in many areas, and a general shortage of insect life may prove to be
telling later in the summer when broods are being counted before the shooting
season opens.
Further south in Cheshire, Heather Trust
board member Richard May has been working on “Maze Cutting”, which includes customised
“lay-bys” and loops in areas of managed heather so that young birds have
somewhere to dry out in periods of wet, windy weather. A little imaginative
thinking can really start to “tweak” wider habitat management plans in favour
of groundnesting birds, and while these often feel like small details, we
believe that they can deliver a big impact when seen as a whole.
The Heather Trust showcases the work put in
by moorland owners and keepers in order to generate discussion around new
techniques and ideas to boost productivity. A good deal of this information was
fed into the Moorland Forum’s Principles of Moorland Management guidance which
will soon be published to establish something like “Best Practice” guidelines
for heather management.
