A Regional Red List is a report of the threatened status of species within a certain country or region. It is based on the

Assessing extinction risk on a regional scale

The IUCN Categories and Criteria were initially designed to assess the conservation status of species globally, however there was a demand for guidelines to apply the system at the regional level. In 2003, IUCN developed a set of transparent, quantitative criteria to assess the conservation status of species at the regional and national level. This approach is now being applied in many countries throughout the world. Recently, Regional Red Lists have been completed for Mongolian Mammals and Fishes. These have also been accompanied by Summary Conservation Action Plans, detailing recommended conservation measures for each threatened species.

Creating a Regional Red List

A Regional Red List may be created by any country or organisation by following the clear, repeatable protocol. The process is as follows: # All information relevant to a species conservation status is collected, including species distribution, population trend information,

habitat In ecology, habitat refers to the array of resources, biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species' habitat can be seen as the physical manifestation of its ...

, ecology and life history information, threats to the species and conservation measures currently in place. # A conservation assessment is made, using the IUCN Regional Categories and Criteria. # A regional workshop is held in which experts review the assessments, make any corrections necessary and add additional information. # The assessments are then collated into a Regional Red List document. # A Summary Conservation Action Plan may also be created.

Towards 2010 targets

In April 2002 at the

Convention on Biological Diversity The Convention on Biological Diversity (CBD), known informally as the Biodiversity Convention, is a multilateral treaty. The Convention has three main goals: the conservation of biological diversity (or biodiversity); the sustainable use of its ...

(CBD), 188 nations committed themselves to actions to “…achieve, by 2010, a significant reduction of the current rate of

biodiversity loss Biodiversity loss happens when plant or animal species disappear completely from Earth (extinction) or when there is a decrease or disappearance of species in a specific area. Biodiversity loss means that there is a reduction in Biodiversity, b ...

at the global, regional and national levels…”. When a Regional Red List is compiled at regular intervals, it can provide information about how the status of the region's

biodiversity Biodiversity is the variability of life, life on Earth. It can be measured on various levels. There is for example genetic variability, species diversity, ecosystem diversity and Phylogenetics, phylogenetic diversity. Diversity is not distribut ...

is changing over time. This information may be useful to policy makers, conservationists, and the general public, as it may assist countries in meeting their obligation to the CBD.

Building the Regional Red List Network

Currently, a global network of countries and individuals working on Regional Red Lists is being developed. This will include a centralised online database where Regional Red List assessments and Action Plans can be stored, managed, and made accessible. With this regional network there will be opportunities to learn from each other's experiences in applying the IUCN Categories and Criteria and in using this information for conservation planning and priority setting.

British reviews of conservation status

Two public bodies in Britain,

Natural England Natural England is a non-departmental public body in the United Kingdom sponsored by the Department for Environment, Food and Rural Affairs. It is responsible for ensuring that England's natural environment, including its land, flora and fauna, ...

and the Joint Nature Conservation Committee (JNCC), have produced British Red Data Books and other reviews of different plants and animals assigning their conservation status according to IUCN Red Data Book criteria. In 2016 the JNCC produced a spreadsheet which incorporated these reviews and lists of threatened species based on other criteria such as Biodiversity Action Plan Priority Lists and Schedules of the Wildlife & Countryside Act.

uses the following definitions for uncommon species not rare enough to be included in the Red Data Book: :Nationally important site for a species is one which has more than 1% of the British population. :Internationally important site for a species is one which has more than 1% of the north-west European population. :Nationally scarce species are those which occur in 16–100 10 km squares in Great Britain :Nationally rare species are those which occur in 1–15 10 km squares in Great Britain.
