Practical measures to prevent or to offset unavoidable damage
There are a number of measures that can be taken, both before the commencement
of coastal
defence operations and while the work is being carried out. It is
important that all contractors are informed in advance of the procedures they
must follow to limit any impact on the vegetated shingle. More specific guidance
is available when emergency
works are needed.

Guidance: Preventative measures that can be taken are:
- brief the works unit/contractors before commencement of work to ensure
that each individual is clear about the measures being taken;
- require contractor to appoint environmental supervisor to oversee
environmental issues (as condition of planning approval);
- limit the number of beach access points for vehicles and if possible,
ensure vehicles keep to a limited track;
- clearly define beach access points avoiding any vegetated areas where
possible. If the loss of some vegetation is unavoidable, ensure that
it is limited to those communities which will be able to re-establish
in the relatively short term;
- demarcate any particularly valuable or important areas of vegetation
prior to commencement of operations to ensure its protection. Use old
groyne timber, tape or any other highly visible barrier laid around
the perimeter. Keep all vehicles, machinery and people out of the marked
area. Some practical
approaches were successfully applied at Dungeness;
- if possible, wash imported marine-dredged shingle to prevent nutrient
enrichment;
- if possible, use imported shingle of a suitable type/size for vegetation,
at least in those more stable areas where plants are likely to recolonise;
- if possible, limit vehicle movement along the beach to below High
Water Mark to prevent impact to vegetation or compaction of shingle
on the ridge;
- limit work to the period outside the bird-nesting season. Shingle
nesting birds generally nest between March and August;
- include information about the shingle vegetation protection measures
that are being taken, in any interpretation on the site.
