In the past the Species Status
Assessment project assigned conservation status to our flora and
fauna using the internationally-approved IUCN Red Data Book
criteria and categories. These reviews were published in a
series entitled Species Status. Some
reviews had detailed data sheets, giving biological and other
information relevant for conserving each species (for example, the
Diptera reviews, Species Status numbers 2 and 3),
while others listed the new conservation status assigned to each
species, with supporting reasons and evidence for these
judgements. These Species Status reviews can be
downloaded as electronic files from here.
Three hundred and eleven taxa were assessed for this review of water beetles of Great Britain.
Produced as part of the JNCC's Species Status Assessment project, this report contains the first assessment of British Butterflies against the new IUCN criteria (IUCN, 2001).
The SSA project was established by JNCC in 1999. The project is the means by which the statutory conservation agencies, in partnership with voluntary conservation organisations and leading specialists, assign conservation status to British species and regularly revise previous Red Data Books and National Reviews. By assessing all taxa to the same standards, comparisons between taxa and between geographic areas are made easier. Such an undertaking is not without difficulty: species that have different life spans, different ecological niches, different reproductive strategies etc, do not always lend themselves to easy comparisons.
This present volume deals with the Superfamily Empidoidea as defined by Chvála (1983), which total 673 British species in the latest Diptera check list (Chandler 1998a), now increased to 677 species (as of March 2003; Stubbs (2003)).
The present volume deals with those Nematocera and Aschiza which were listed but not provided with Data Sheets by Falk (1991). There are sixteen currently recognised families, comprising about 1226 British Isles species, which are considered in this review.
Produced as part of the JNCC Species Status Assessment project, to assess the status of vascular plants throughout Great Britain. IMPORTANT
: the Vascular Plant Red Data List for Great Britain has recently been revised (2006). The amended version has been incoporated into a a single downloadable spreadsheet of conservation designations
. This spreadsheet has various types of legislative and status lists and also includes other taxonomic groups.
Great Britain is home to 60% of the entire European bryophyte flora. This book gives full species accounts for 176 species with a further 76 listed as 'near threatened'. Already it is contributing to the species conservation programmes co-ordinated by the UK Government's Biodiversity Steering Group.
Contains 177 data sheets describing the appearance, distribution, ecology and conservation requirements of Britain's most threatened species of lichens.
Stoneworts or charophytes are a group of relatively large and attractive algae that grow mainly in calcareous fresh water and in brackish lagoons. This book describes the ecology, threats, status and conservation of the 21 most threatened stoneworts in Britain and Ireland, with a distribution map and drawing of each species. Also includes an identification key.
