Pressure
1 Indicator
definition and unit of measurement
Loss,
damage and fragmentation of designated protected areas (all categories) due to
human activities.
The
unit of measurement is percentage or km
2
of protected area affected in relation to an appropriate baseline year (e.g.
1992).

3 Significance
Purpose:
The
indicator represents pressures on the integrity of biological systems, hence
species and their habitats, within protected areas.
Relevance:
Protected
areas have a high international profile (public and institutional) and hence
strong policy resonance. Because of the limitations (see below) protected area
integrity
per
se
may not fully reflect total biodiversity.

4 Methodological
description and underlying definitions
Underlying
definitions and concepts:
Loss,
damage and fragmentation of protected areas represent loss of biodiversity
resulting from direct negative impacts on ecological integrity at various
levels: population, species and habitat.
Measurement
methods:
Standardised
definitions and objectives are required, particularly with regard to the causes
and consequences of "fragmentation”. Fragmentation as a pressure should
be measured according to sector; transport: roads length per total protected
area, energy: power lines length per area, tourism: area occupied by tourist
establishments, etc.
Limitations
of the indicator:
(i)
Definitions of "protected area" categories needs harmonisation throughout
Europe (e.g. following the IUCN typology) because, amongst other things,
pressure on protected areas is dependent on the degree of priority afforded by
sovereign states to the integrity of protected areas in face of pressures for
economic development.
(ii)
Definition of “loss” or “damage” and the ecological
implications of “fragmentation” needs clarification and
standardisation.
(iii)
Data may concentrate on single events (building of a road, land drainage etc.)
and may be much less effective at indicating the deterioration in the
biodiversity value and provide no direct indication of the changes in
ecological quality of the protected area.
(iv)
The category of damage should be identified: temporary or permanent, short or
long-term, because it is important whether the activity causing the loss or
damage/fragmentation is potentially reversible (e.g. road building) or causes
more intractable changes in the ecosystem (e.g. non-point source pollution).
Alternative
definitions:
An
indicator based solely on loss of protected areas may be more appropriate since
data on damage and fragmentation are more problematic. The European Topic
Centre, Copenhagen is currently developing a “pressure index” for
protected areas to identify threats to protected areas from the surrounding
land use. The pressure index is calculated from the frequency/intensity of
threats (pressures) present within buffer zones around the protected area.
