| Don’t
forget heather moorlands ... |
| Moorland is a broad term
used to describe any land that is not actively farmed or under trees.
It includes many types of habitat, such as bogs, juniper scrub, streams
and grassland as well as heather moorland or ‘heath’.
The first moorlands in Britain date back to at least 8 000 years ago when fire was used by Middle Stone-Age hunters. Fire was used to flush animals from wooded areas, and onto the spears of waiting hunters. Fire was also used to create clearings in woodland so that deer and other animals could graze in higher numbers where the hunters knew they would be. Britain has most of Europe’s moorland
and nearly all of its heather moorland! |
In the Cairngorms National Park, 41% of the landscape is dominated by heather moorland - a Cinderella habitat often overlooked as the background in which other, more interesting habitats occur. Moorland would revert to woodland if
it was not burnt or grazed regularly. Fire maintains the open character of
moorland and is used to create a mosaic of different aged stands of
heather. |

| Moorlands
are shrinking! |
| Between
the 1940s and 1980s, heather moorland in
Scotland was reduced by 23% and it declined at a similar rate between
1990 and 1998.
The main reason for this decline is the
spread of forestry plantations but heavy grazing pressure and a decline
in grouse shooting resulting in less moorland management by burning
are also to blame. Yes! Heather moorland is the mainstay
for Britain’s only endemic bird species, the red grouse, and three-quarters
of the population of its main predator, the hen harrier. |
Moorland
biodiversity results from the mosaic of different habitats that
it may contain and because of the use of fire to create differently
aged stands of heather. |

| What
about shooting over heather moors? |
| Heather moors
are managed primarily for the red grouse. This fast flying bird is difficult
to shoot and is popular because this provides great sport to the ‘guns’.
The winter limits the numbers of grouse on a moor because this lean period will permit the survival of only so many birds. Moorland managers aim to shoot only the surplus grouse that would die naturally, over the winter period, in order to maintain good stocks of grouse into the future. Land managed for grouse shooting supports
higher densities of notable bird species such as golden plover, lapwing
and curlew than comparable habitat managed purely for grazing. |
The persecution of raptors, often linked to shooting interests, occurs over much of Scotland but more effective policing of wildlife law has led to an increase in numbers. The control of certain species by gamekeepers, such as the predatory mink, has benefited wildlife such as ground-nesting birds and the increasingly rare water vole.

| Why
are there sheep on moorland managed for shooting? |
| Some grazing helps
to maintain the open nature of heather moorland and the droppings provide
a home for insects that are a food source for the grouse chicks.
The economics of land ownership have led to an increase in sheep numbers on moorland since the 1950s. Red deer numbers have increased in this time too. Unfortunately this increase in the numbers
of grazers reduces the ability of the heather to regenerate and this
results in the replacement of heather moor by species-poor grassland. |
The
management of moorland for both shooting and farming interests
is the ideal for moorland plant diversity, as long as the grazing density
is low and burning takes place in small patches every 7-15 years. This delicate balance is what we are trying to achieve at the two demonstration sites managed by the Cairngorms Moorland Project. |
|
| How
many grouse are there? |
| Grouse numbers
are currently low for a number of reasons such
as natural variability in population numbers, increased exposure to disease,
climate change, etc..
Records reveal that the demonstration
moor at Blairfindy once produced up to 800 grouse per year. |
The
decline in grouse numbers has resulted in the loss of moorland
to other activities. Unfortunately, the future of this internationally
rare habitat is threatened by the low numbers of grouse that provide
the income to support it's management.. |
