Objective:
Maintain the plant communities of the coastal turf in a favourable
condition
Factors:
Golfing
The Golf Course has, in the past, cut areas of turf within the
Reserve. This practice should not be stopped, since the bare
ground thus created gives rise to two types of specialized plant
communities (Chapter III, section 6(f)). If no new turf cutting
operations have been started by 1970, the Biological Sub-
Committee should recommend two or three areas, not more than a
quarter of an acre each, from which the turf should be cleared.
GRAZING
The problem of allowing grazing on the Reserve was raised
by the
factor of Luffness Estate and the Tenant Farmer in 1964 and 1965.
The advice of the Nature Conservancy, and a prescription of this
Plan, is that there should be no grazing in the vicinity of the
Marl Loch, the Curling Pond, or the marshes and moist ground
associated with either of these areas. In order to graze this
ground, herbicides would have to be used to destroy the horsetail
(Equisetum spp.), which occurs in one of the most interesting
plant communities in the Reserve, and which is poisonous to
cattle. The damage to the saltings and to the banks of the Marl
Loch by the cattle's hooves would also be considerable. The area
considerably to the east of the Marl Loch, a small part of which
was enclosed and cut for silage in 1967 (Plate 13), may be
suitable for grazing. However, part of this area would probably
require a ground drainage system, which would influence the
seepage of water into the Marl Loch and its associated marshes.
Hence, it is recommended that no ground drainage schemes are
carried out within the Reserve. The erection of fences,
especially to the west of the Marl Loch, should be opposed, since
this would destroy the 'sense of space'. The advice of the Nature
Conservancy and the Biological Sub- Committee should be sought in
all aspects of grazing.
Trampling by HORSES AND PONIES
A consideration of the damage to plant communities by the riding
of horses and ponies, and prescriptions for routing these
animals, will be found in section 3(b) (v) of this Chapter.
SEA BUCKTHORN
There are three main areas of sea buckthorn, Hippophae rhamnoides
— beside the Marl Loch, at the north of the Yellow Mires, and
near the Hummel Rocks. With the lack of rabbit grazing pressure,
it is estimated that the forward edge of these clumps is
advancing at two to three feet per year (Plate 15), and,
particularly on the more open teschen-ite soils, self-seeded
bushes are becoming established. If it is possible, the three
clumps of sea buckthorn should be maintained at their 1967 size
by frequently cutting all outspreading shoots. It is also
prescribed that all other plants of sea buckthorn should be dug
out before they become too large to control.
OTHER SPECIES
The giant hogweed, Heracleum mante-gazzianum (Plate 16), an alien
that is spreading in the Lothians, is undesirable because it
forms dense stands in which few other plants are able to grow. It
is, therefore, prescribed that this plant be exterminated from
the Reserve.
Hawthorn is not desirable in the Reserve since it causes the open
character of the Reserve to be destroyed (Plate 14). Later in
this Chapter, section 5, the boundaries of the Reserve are
discussed, and an area which the hawthorn would be allowed to
colonize is demarcated. Over all other areas of the calcareous
grassland, the hawthorn should be cut.
