The status and distribution of interest features listed under the Habitat Directive Annexes 1 and II was originally recorded in the following JNCC publication:

Jackson, D.L. & McLeod, C.R. (Editors), (2000), Handbook on the UK status of EC Habitats Directive interest features: provisional data on the UK distribution and extent of Annex I habitats and the UK distribution and population size of Annex II species, Revised 2002, JNCC Report 312, 180 pages, ISSN 0963 8091

An archive copy of report 312 is available in the form of a fully interactive spreadsheet and a supporting explanatory PDF.

Note that this report was originally available primarily as a set of web pages. These web pages have been systematically updated in September 2008.

The information originally presented in JNCC report 312  has now been superceded (Current Distribution of Habitats Directive Interest Features) mainly by extracting information (principally distribution maps and UK population/extent figures) from the UK’s report under Article 17 of the Habitats and Species Directive. The replacement web pages should no longer be referred to as JNCC report 312, though they can be used for similar purposes – ie to see a map of the current UK distribution of each interest feature and to compare the UK distribution maps to the distribution of the SACs hosting each feature. The revised UK distribution maps (2008) often differ from the Report 312 (2002) maps. In some case this represents “real world change” but in many cases it reflects new data sources or new interpretations of existing data sources.  Many of these changes are discussed in some detail in the habitat/species accounts submitted as part of our Report under Article 17 of the Habitats Directive.
