1 From raw data to Red List: The Red List assessment process and role of the Red List Assessor The IUCN Red List of Threatened Species

2 From raw data to Red List WHAT IS A RED LIST ASSESSMENT? The IUCN Red List of Threatened Species

3 From raw data to Red List IUCN Red List assessment: an estimate of extinction risk What is the likelihood of a species becoming extinct in the near future, given current knowledge about population trends, range, and recent, current or projected threats? It is not a list of species that are priorities for conservation action Illustration copyright Bob Diven

7 Components of a Red List assessment 1. Red List category and criteria Purple Skimmer Libellula jesseana Vulnerable A2a;B2ab(iii) 2. Documentation supporting the category and criteria Population size, trend and status; range; threats; conservation measures; etc. 3. Map of species distribution

8 What can be assessed? IUCN Red List Categories and Criteria are used to assess: All described taxa (species, subspecies, varieties), except microorganisms Undescribed taxa, only if they are: A clearly distinct species Museum/herbarium voucher references are provided Distribution information is available There is clear conservation benefit to assessing the species At the global level At the regional/national level only with the Guidelines for Application of IUCN Red List Criteria at Regional Levels Wild populations inside their natural range (including populations resulting from benign introductions)

9 HOW CAN RED LIST DATA BE USED?

10 Analysis and indicators Conservation planning and priority-setting International conservation policy Inform private sector decision-making Education and public awareness Guidelines_Data_Use.pdf

11 Red List Index Trends in overall extinction risk over time: genuine change

12 Conservation works 37 recent improvements in status in mammals 5% of threatened mammals have increasing populations 16 birds prevented from going extinct in the last 15 years due to conservation efforts Equus przewalskii Black-footed Ferret Yellow-eared Parrot

13 Essential tools for Red List assessments

14 From raw data to Red List RED LIST ASSESSMENT PROCESS The IUCN Red List of Threatened Species

15 From raw data to Red List Red List assessment process: Rigorous process ensures high quality assessments supported by strong data Final review by RLU Review & Consistency Check Assess species (independently/at workshop): Red List Category and Criteria + range map + supporting documentation Pre-assessment (Project Managers or Assessors): convene experts and compile data, draft supporting documentation + range map Publish on Red List FORUM

17 From raw data to Red List Who is involved in producing a Red List assessment? Project Managers Assessors Contributors (optional) Reviewers IUCN Red List Unit Coordinate assessment projects; finalize assessments; liaise between assessors/reviewers/iucn RLU Provide data; apply the Red List Categories and Criteria considering all relevant data Provide data and contribute knowledge to the assessment, but do not apply the Red List C&C Review each assessment before publication to ensure data is comprehensive and accurate Final assessment sign-off; manage Red List database/website; field petitions and enquiries

19 Assessment Review Process Within IUCN network Specialist Groups, Red List Authorities Global Biodiversity Assessment projects IUCN-led regional projects Assessors Unreviewed assessment Reviewers At least 1 for every assessment Reviewed Assessment assessment Outside IUCN Regional/national assessments (endemic species) Other external assessors Unreviewed assessment Quality-checked, reviewed assessments IUCN Red List Unit

20 From raw data to Red List ROLE OF A RED LIST ASSESSOR The IUCN Red List of Threatened Species

21 From raw data to Red List What does a Red List Assessor do? 1. Compile all currently available data on population status, distribution, ecology, use/trade, threats & conservation measures: Across the species entire global range Data may come from published studies, unpublished reports, grey literature, personal knowledge, etc. 2. Assign a Red List category and criteria based on the available information 3. Justify the assessment following the documentation requirements 4. Prepare a range map following the mapping standards 5. Know who to submit the assessment to for review and submission to the IUCN Red List Unit.

22 Red List Assessors are vital to listing species on the IUCN Red List! A Red List Assessor: Required supporting information Categories & Criteria Range Map

23 From raw data to Red List How can Red List Assessors ensure assessments are rigorous and defensible? Understand the Categories & Criteria and apply them properly Justify the assessments with thorough supporting data Follow the documentation standards Provide relevant references Submit a good map Double check for consistency and for errors Work with other relevant groups doing Red List assessments High quality assessments get published more quickly better for conservation!
