The first project activity is to carry out an assessment of the extent and condition of biodiversity across Kent and Nord-Pas de Calais. It consists of the development of a regional and cross-border vectorial and georeferenced database of natural habitats to a 1/10 000 scale.

The objectives of this activity are:

  • the devolpment of a cross-border map of natural habitats
  • the update of the natural habitats  in Kent and a georefenreced database of natural habitats in Nord-Pas de Calais
  • a habitat connectivity/fragmentation index assessment tool 


Over two years have been necessary to achieve the natural habitat cross border map, of which main phases were:

  • the definition of a common classification adapted from the European classification CORINE biotopes (level 3). It is composed of 50 habitat classes reflecting the specificities of Kent and Nord-Pas de Calais, transcribed in a common legend
  • a cross border map of natural habitats with around 700 maps- access the maps here
  • the interpretation of aerial photography from 2005 and 2009 and field survey on sample areas in Nord-Pas de Calais- available from here
  • an update of the Kent Habitat Survey, previously carried out in 1990 and 2000, using a combination of aerial photograph from 2008 and selective field surveys
  • a connectivity/fragmentation index assessment tool - view the tool's manual here

Documents and other information:

  • Photo interpretation in Nord-Pas de Calais and the cross border map - the report is available from here
