What are Conservation Assessments?
Species conservation assessments are carried out in order to systematically determine the conservation status of a species. There are many different types of assessments that can be undertaken at a variety of scales and with a variety of methods, but they all essentially aim to determine how likely it is that a species will go extinct in the near future.
Global IUCN Red List Assessments
Assessments that are undertaken at this scale require a species’ entire global population to be assessed. The most trusted global assessment programme is the IUCN Red List of Threatened Species. The IUCN Red List assesses species under a well-established, quantitative protocol that is universally applicable to all species (marine or terrestrial, plant or animal). Volunteer experts (including those that are members of IUCN SSC Specialist Groups) collaborate to author the assessments with the help of other expert reviewers and IUCN staff.
Regional IUCN Red List Assessments
Conservation assessments are often also undertaken at the scale of large geographic regions. The purpose of such assessments is to determine whether species are at risk of regional extirpation due to the threats they face. Regional assessments make it easier to implement conservation actions in particular areas, which may not have been apparent at the global scale. The IUCN hosts regional workshops with experts from the area in order to complete these assessments.
National Conservation Assessments
Countries around the world often undertake conservation assessments at the national scale in order to gauge their contribution to conservation and report on national biodiversity commitments such as the Convention on Biological Diversity. Such assessments can help a country to determine whether their environmental stewardship is adequate for the species within their borders. Although most countries follow the IUCN Red List Categories and Criteria, others modify them based on their own needs, and some even take on their own assessments independent of IUCN Red List protocols.
What is the IUCN Red List of Threatened Species?
The IUCN Red List of Threatened Species™ provides taxonomic, conservation status and distribution information on plants and animals that have been globally evaluated using the IUCN Red List Categories and Criteria.
IUCN Red List Authorities have been established for all major taxonomic groups included on the IUCN Red List. In our case, the IUCN Red List Authority (RLA) is the SSC Specialist Group for Seahorses, Pipefish, and Sticklebacks. RLAs facilitate species assessments for the IUCN Red List by collating data and maps and coordinating their review by well-qualified experts, and by contributing directly to the assessments.
Our Specialist Group’s role as the IUCN Red List Authority is to ensure that all species within our jurisdiction (all fish in the orders Gasterosteifiormes and Syngnathiformes) are correctly assessed against the IUCN Red List Categories and Criteria at least once every ten years and, if possible, every five years . The intention is that no new species assessment will be included on The IUCN Red List until it has been reviewed by one or more members of the RLA. This review system places greater responsibility on the SSC network and its partners to ensure that what appears on the IUCN Red List is credible and scientifically accurate.
Learn more about IUCN Red List Assessments
You can learn all about the IUCN, the Red List, and the protocols used for the assessments in the online course offered by the IUCN. If you complete the course and pass the exam, you can even perform Red List assessments on species you are interested in. Contact firstname.lastname@example.org if you’d like to help out with assessments of species within our remit.
