Common Standards Monitoring was piloted in 1998 and
implementation commenced in April 1999. This report is based
on data for the period April 1998 - March 2005. The data were
provided by the country agencies to JNCC in July and August 2005,
using a standard proforma.
JNCC collated these four sets of data (one each for England,
Scotland, Northern Ireland, and Wales) into a UK wide database of
condition assessments for features on SSSIs (ASSIs in Northern
Ireland), SACs, SPAs and Ramsar sites. The database contains
a row for each feature reported on each designated site. A
feature on a double-badged site (e.g. a site designated both as a
SSSI and as a SAC) is recorded as two rows in the database
- one row for each designation type. Any reader wishing
access to the raw data on which this report is based should make
their request to the relevant country agency monitoring
contact.
Data were split into 44 reporting categories based on
Biodiversity Action Plan broad habitats, taxonomic groups, and
broad divisions of earth science. Every assessment was
assigned to a single reporting category. JNCC developed
standard graphs, maps, and tabulations for each reporting
category. For SACs and SPAs, JNCC are able to collate lists of
qualifying features that have not yet been assessed. This
cannot be done for SSSIs because there is not yet a UK-wide list of
notified interest features.
In addition to the condition assessments, data were also
collated on 'adverse activities' and 'management measures'.
'Adverse Activities' are those factors which are thought to be
leading the feature into unfavourable condition. 'Management
Measures' are the actions which are helping to maintain favourable
condition, or return a feature from unfavourable to favourable
condition. More than one activity or measure can be recorded
for each assessment of the condition of a feature.
To facilitate map display on the website and hard copy report,
it was decided to display the spatial locations of the assessments
on a 10km square basis. For each and every monitoring
assessment a 10km square is calculated based on the site
centroid.
The condition maps use this 10km square to group all of the
condition assessments within a reporting category - for example,
ten different assessments are reported for lowland calcareous
grassland on SSSIs within grid square ST45. As only one of
these ten, i.e. 10%, is currently favourable, this square is
coloured red on the 'current' SSSI condition map for lowland
calcareous grassland. The 'future' map shows this square as
green. This is because seven of the ten features are
currently 'unfavourable-recovering'. Assuming that recovery
is achieved for these seven features, at a point in the forseeable
future, eight out of ten, i.e. 80%, of the lowland calcareous
grassland features within square ST45 will be favourable.
Note that no prediction is made on the timescale for recovery for
any feature.
For large SACs (i.e. those falling into more than one 10km
squares), condition assessments have been allocated to all the 10km
squares which, to the best of our knowledge, host the
feature. This has been possible because for SACs there are
10km square distribution maps for each interest feature. JNCC
do not hold equivalent spatial data for SPA, Ramsar or SSSI sites
and have, therefore, only been able to use the site centroid to
locate the interest features on these site types.
The figure for favourable condition in a few of the precharts
is marginally different from that shown in the summary statistics
table - this is a result of rounding to show small segments
effectively; the figures in the summary statistics table are
correct.
