Annex 1
POSSIBLE IMPACTS OF RELEVANCE TO NATURE CONSERVATION
The following provides an outline of nature
conservation impacts that may need to be considered in an environmental
assessment of a wave or tidal energy development.
THE DEVELOPMENT:
BROAD RANGE
OF CONSIDERATIONS
Temporal:
— Pre-installation.
— Construction.
— Operation.
— Decommissioning.
Spatial:
— On site/off site buffer area/area
of influence.
— Cable route.
— Land-fall.
— Other (eg construction site, spoil disposal sites).
Cumulative:
— Over time.
— In combination with other projects/activities.
RANGE OF
NATURE CONSERVATION
INTERESTS
There are likely to be a range of interests
that could be affected both directly and indirectly by a wave
or tidal energy development.
Direct:
— Sediment transport.
— Marine habitats.
— Marine benthos.
— Mobile acquatic species (Fish, mammals).
— Birds.
— Sedentary and reef-forming acquatic species.
Indirect:
— Coastal processes.
— Coastal habitats and associated species.
— Birds.

p = pre-construction, c = construction phase, o = operation
phase, d = decommissioning
In addition to the above impacts, there are landscape/seascape
and cultural impacts, and impacts of associated infrastructure,
which could be indirectly linked to nature conservation (eg change
in land use, restriction on sea use such as navigation or fisheries).
