"The variability among living organisms from all source
including, (biological diversity) inter alia,
terrestrial, marine and other aquatic ecosystems and the ecological
complexes of which they are part; this includes diversity within
species, between species and of ecosystems." (UN Convention
on biological Diversity, 1992.)

characteristics) together with its recurring associated community

The abbreviated term for Council Directive 79/409/EEC of 2

A natural or semi-natural feature for which a SAC/SPA has been
feature selected. This includes any Habitats Directive Annex
I habitat, or specific component of their flora and fauna, or
any Annex II species and any population of a bird species for
which an SPA has been designated under a Birds Directive. Any
habitat of a species for which a site has been selected, or
typical species of an Annex I habitat, are also considered to
be conservation features (SNH, 1997).
A statement of the nature conservation aspirations for a site,
expressed in terms of the favourable condition that we wish

Favourable Conservation Status
A range of conditions for a natural habitat or species at which
the sum of the influences acting upon that habitat or species
are not adversely affecting its distribution, abundance, structure
or function throughout the EU in the long term. The condition
in which the habitat or species is capable of sustaining itself
on a long term basis.
The abbreviated term for the Council Directive 92/43/EEC of
21 May 1992 on the Conservation of Natural Habitats and of Wild

The ability a habitat, community or individual (or individual

The European network of protected sites established under the
Birds Directive and the Habitats Directive (SACs andSPAs).
A species that has been introduced by human agency (deliberately
or otherwise) to an area where it has not occurred in historical
times (taken as being since 500 years before present) and which
is separate from and lies outside, the area where natural range
extension could be expected. The species has become established
in the wild and has self-maintaining populations. (Eno et
Operations which may cause deterioration or disturbance
Any activity or operation taking place within, adjacent to
or remote from a European marine site that has the potential

for which the site was designated.
Plans and Projects
Any proposed development that is within a relevant authority’s
function to control, or over which a competent authority has
a statutory function to decide on applications for consents,
authorisations, licences or permissions .
Polluter Pays Principle
When production processes threaten or cause damage to the environment,
the cost of necessary environmental measures should be borne
by the producer and not society at large, giving incentives
to reduce pollution.
The assumption that where there are real threats of damage
to the environment, lack of scientific information should
not be used as a justification for postponing measures to prevent
such damage occurring.
The ability of a species to return to its former status once
