Description
Major effects on the feature/population, which would have a sufficient effect to
irreversibly alter the nature of the feature in the short-to-long term and affect its longterm
viability, for example more than 20% habitat loss or damage.
Effects that are detectable in short and long-term, but which should not alter the longterm
viability of the feature/population, for example between 10 - 20% habitat loss or
damage.
Minor effects, either of sufficiently small-scale or of short duration to cause no long-term
harm to the feature/population, for example less than 10% habitat loss or damage.
A potential effect that is not expected to affect the feature/population in any way;
therefore no effects are predicted.
12.2.43 The level of a potential effect on each VOR was determined by considering the type and
magnitude of the effect (Table 12.4 and Table 12.5) in relation to the conservation
importance (sensitivity) of the VOR (Table 12.3). The level of effect is described as
Substantial, Moderate, Slight or Negligible, or within a range (e.g. Substantial - Moderate) as
illustrated in Table 12.6.

Criteria
Only adverse effects are assigned this level of importance as they represent key
factors in the decision-making process. These effects are generally, but not
exclusively, associated with sites and features of international, national or
regional importance that are likely to suffer a most damaging effect and loss of
resource integrity. A major change at a regional or district scale site or feature
may also enter this category.
These beneficial or adverse effects are likely to be very important
considerations at a local or district scale and, if adverse, are potential concerns
to the scheme and may become material in the decision making process.
These beneficial or adverse effects while important at a local scale are not likely
to be key decision making issues. Nevertheless, the cumulative effect of such
