| The Roe Deer frequently lie up
in the control section in the day since the vegetation in this section has now grown up
enough to provide an effective shield. Their feeding preferences include the buds and
leaves of deciduous trees and shrubs, brambles, ivy , herbs, conifers, fern, heather and
grasses. The effects they may be having on the the structure and distribution of the plant
community is unknown.
In other heathland areas (such as Lincolnshire and East Anglia), rabbits have been
shown to have a devastating effect on the vegetation, which only recovers when they are
excluded by some form of fencing. Some grazing is beneficial in that it controls the
spread of grasses and tree seedlings, but over-grazing can be very detrimental. Again it
is not known in what numbers the rabbits occur on the site, nor the effects they may be
having. However, their numbers are clearly not excessive and it is unlikely that they are
having a major detrimental effect. Heather (Calluna), fine grasses such as Agrostis
spp., Bell Heather and seedling Gorse are at the top of their feeding preferences on
heathland sites (Chadwick).
It must be noted that most of the management techniques used on the project site to
prevent the succession to woodland are non-selective, reducing all vegetation down to the
same level. Grazing by animals, whether
domestic or wild, is selective as illustrated above and will therefore affect the
vegetation of a site significantly differently to brushcutting.
Other Animals
The fauna on the heathland site has not yet been either qualitatively, or
quantitatively surveyed. However, a number of animals have been seen while carrying out
the annual vegetation surveys
Tiger Beetles (Cicindela campestris) which are very characteristic
heathland inhabitants, have occurred on the project site since 1996. Orthopterans
(grasshoppers / crickets) were abundant in the grasses in the summer. Numerous spiders and
several species of butterflies and dragonflies were commonly seen. Detailed
qualitative and quantitative surveys of the fauna of the project site are planned for the
future. |
