The England Habitat Network (EHN) was first developed by English Nature in 2005 in
an attempt to systematically evaluate the impact of fragmentation and land use
intensification on areas of conservation value, at a national scale. A series of
geographical information layers were subsequently published, at the end of 2006,
that defined areas of landscape where clusters of sites might be functioning as
„ecological networks‟, i.e. linked by the frequent exchange of propagules and/or
individuals. Although indicative, this analysis suggested that a significant land area,
beyond existing sites, might have retained some potential for species movement in
less intensively managed landscapes Attribution statement: Attribution statement: © Natural England copyright. Contains Ordnance Survey data © Crown copyright and database right [year].
