Biodiversity Databank
A database of national biodiversity including such information as species name, population size, range, habitat and ecology and threats, used to compile all the information required for a National Red List.  Databanks may be public or private, depending on the creators or the relevant projects’ aims, and may not have been developed for the specific purpose of conducting a Red List.

IUCN
The International Union for the Conservation of Nature.  For more information see https://www.iucnredlist.org/.

IUCN Red List of Threatened Species™
The IUCN Red List of Threatened Species™ is widely recognized as the most comprehensive, objective global approach for evaluating the conservation status of plant and animal species.  For more information, see www.iucnredlist.org.

National Biodiversity Strategies and Action Plans (NBSAPs)
National Biodiversity Strategies and Action Plans (NBSAPs) are the principal instruments for implementing the Convention on Biological Diversity (CBD) at the national level.  The Convention requires countries to prepare a national biodiversity strategy (or equivalent instrument) and to ensure that this strategy is mainstreamed into the planning and activities of all those sectors whose activities can have an impact (positive and negative) on biodiversity.  For more information, see http://www.cbd.int/nbsap.

National Red List Network
An open network of individuals and groups working on sub-global Red Lists around the world, created to aid sharing of knowledge and expertise, and foster collaboration.

National Red List
A document or database containing details of a set species’ conservation status at a national scale.

NRLWG
The National Red List Working Group reports to the SSC and is responsible for overseeing the use of the IUCN Red List Categories and Criteria (particularly the Guidelines for Application of IUCN Red List Criteria at Regional Levels) at the national level, and for building linkages between the IUCN Red List of Threatened Species and species assessment processes at national levels. .

Red List Index
The IUCN Red List Index (RLI) measures overall trends in extinction risk for sets of species, based on genuine changes in their status over time.  For further information, see http://www.iucnredlist.org/about/publications-links#Red_List_Index.

Regional Red List
A document or database containing details of a set species’ conservation status at any sub-global scale.  Most often applies to a region of several countries, but may also be refer to a particular habitat or ecosystem spanning several countries or a sub-national assessment.

Regionally Extinct (RE)
Category for a taxon when there is no reasonable doubt that the last individual potentially capable of reproduction within the region has died or has disappeared from the wild in the region, or when, if it is a former visiting taxon, the last individual has died or disappeared in the wild from the region.

SIS
The Species Information Service (SIS) comprises the data management tools/software/services which facilitate the efficient collection and compilation of species biodiversity and Red List assessments. https://www.iucnredlist.org/assessment/sis.

Species or Summary Conservation Action Plan
A document outlining a specific, measurable and achievable plan for the conservation of one or several species, often based on the results of a Red List assessment. For more information see the IUCN Species Conservation Planning Sub-Committee’s “Strategic Planning for Species Conservation” overview and handbook on their webpage.

The Convention on Biological Diversity (CBD)
The Convention on Biological Diversity is an international treaty to sustain the rich diversity of life on Earth.  For more information see http://www.cbd.int.
