Global Species Assessment The
IUCN Red List of Threatened Species™, known as the IUCN
Red List, is one approach
for assessing and monitoring the status of biodiversity.
The IUCN Red List is
supported by the Red List Consortium, comprised of the
IUCN – The World Conservation
Union (in particular the Species Survival Commission),
BirdLife International, Conservation
International (in particular the Center for Applied
Biodiversity Science), and
NatureServe. Together these organizations provide the
world’s largest knowledge base
on the global status of species. The 2004 Red List contains
the global status and
supporting information on 38,047 species and is available
on the web at http://www.iucnredlist.org. |

Guidelines / Regional Guidelines The
IUCN Red List Categories and Criteria (IUCN 2001; see
also redlist
categories 2000) were developed for classifying
species at high risk of global extinction, i.e. for assessment
at the global level. At regional, national and local
levels (hereafter referred to as regional level) there are essentially two options:
(1) To publish an unaltered subset
of the global Red List encompassing those species that
reproduce in the region
or at any stage regularly visit the region. This may
be a feasible option, particularly
when the region has a high number of endemics or threatened
near endemics,
or when there is currently a pronounced overall deficiency
of data pertaining
to species status within the region. (2) To assess species’
extinction risk
and publish Red Lists within the specific region. For
the purposes of regional conservation
assessments there are important reasons to assess species’
extinction risk
and publish Red Lists within specific geographically
defined areas. |
