Appendix 3 BAP Priority Habitat Inventories
The following habitat inventories were created by DBRC in 2001-2003, as part of the National Biodiversity Network South West Pilot. The habitats were mapped using County Wildlife Site survey data and aerial photographs available at the time. Some of the inventories have been updated since they were created, but they may not include information from the most recent County Wildlife Site surveys. This means that the information in the inventories is incomplete, and the absence of information for a particular area does not mean that there are no BAP Priority Habitats present.

Coastal salt marsh
Coastal vegetated shingle
Lowland calcareous grassland
Lowland dry acid grassland
Lowland heathland

Appendix 4 Methodology for the Devon species status assessment
A Devon species status assessment was carried out based on a simplified version of the method used by the Joint Nature Conservation Committee (JNCC) for reporting to Europe on species listed in Annexes of the European Habitats Directive (JNCC, 2008). See table below. The assessment for each species is based on available data combined with the expert judgement of those contributing to this report. The national assessment for each species is also given. National assessments are taken from the 2008 JNCC assessment1, the 2008 UK BAP reporting round2 and Birds of Conservation Concern 3, 20093.
Devon species assessment (as per JNCC, 20081).
|
Favourable
|
Unfavourable inadequate
|
Unfavourable bad
|
|
|
Categories of ‘but improving’ or ‘and deteriorating’ can be added to Unfavourable-Inadequate and Unfavourable-Bad.
|
Range
|
Stable or increasing (since 1998), and range sufficiently large to allow long term survival of the species.*
|
Any other combination
|
Large decline since 1998
|
Population
|
Stable or increasing and population large enough to ensure the long term viability of the species in Devon.*
|
Any other combination
|
Large decline 1998
|
Habitat
|
Area and quality of habitat suitable to support a favourable (long term viable) population of the species.*
|
Any other combination
|
Area and / or quality of habitat is clearly not sufficiently large to
ensure the long term survival of the species
|
Future Prospects
|
Main pressures and threats to the species not significant; species will remain viable on the long-term.*
|
Any other combination
|
Severe influence of pressures and threats to the species; very bad prospects for its future, long-term viability at risk.
|
Overall conservation status
|
Habitat or species can be expected to prosper without any change to existing management or policies.
|
Habitat or species require a change in management or policy but the danger of extinction is not so high.
|
Habitat or species is in serious danger of becoming extinct (at least locally).
|
|
One unfavourable bad assessment = overall status is unfavourable bad.
One unfavourable-Inadequate assessment combined with all favourable conclusions = unfavourable-Inadequate. An overall conclusion of Favourable is only reached where all parameters are Favourable or
three parameters are Favourable, and one is Unknown. In cases where there are two or more Unknown conclusions combined with other Favourable conclusions, the overall conclusion will be Unknown.
|
* based on the expert judgement of those contributing to this report.
Data is assessed as - ‘Good’, based on extensive surveys, ‘Moderate’, based on partial data with some extrapolation, or ‘Poor’, based on very incomplete data or on expert judgement.
