More than one in three tree species worldwide faces extinction – IUCN Red List

The IUCN Red List of Threatened Species (the Red List) is the globally recognised standard on assessing extinction risk. Red List assessments are used by the Convention on Biological Diversity, CITES, other inter-governmental agreements, national governments, and conservation planners.  The Red List assigns species into one of 8 categories based on 5 criteria, all with quantitative thresholds. The three highest categories of threat – Critically Endangered, Endangered, Vulnerable – are collectively considered ‘Threatened’. The Red List process has been formalized to support objectivity and scientific rigour. Red List assessments are carried out by SSC Red List Authorities, Red List Partners, IUCN staff, and regional and national agencies. In addition, Red List assessments provide a compendium of information on species, (taxonomy, geographic range, population, habitat and ecology, threats, conservation actions). The Red List operates at global, regional, and national levels. Guidelines for application at national or regional levels have been developed and the National Red List Working Group provides additional support.

Red List Authorities have been established for all major taxonomic groups included on the IUCN Red List. In most cases, the RLA is a sub-group within an IUCN SSC Specialist Group responsible for the species, groups of species or species within a specific geographic area. There are some exceptions; for example, BirdLife International is the designated RLA for all birds.

The process is guided by Rules of Procedure, supported by guidelines on application of the Red List Categories and Criteria, the Species Information Service (SIS) data entry and management system, and certification for assessors and RL trainers. All these materials can be downloaded, free, from the Red List website. A free, online training course for Red List assessors, is available.

Species can be assessed for the Red List at global, regional, and national levels. Guidelines for the Regional (and national) Application of the Categories and Criteria have been developed and support for development of national Red Lists is available from the National Red List Working Group.

How to use

• To check the global Red List status of a species and access the supporting information, visit the species assessment page on the Red List website

WH Sites identify, protect, and preserve cultural and natural heritage around the world that is considered to be of outstanding value to humanity. This is embodied in an international treaty called the Convention concerning the Protection of the World Cultural and Natural Heritage, adopted by UNESCO in 1972. Sites must be of outstanding universal value and meet at least one out of ten selection criteria to be included on the World Heritage List. The criteria are regularly revised by the Committee to reflect the evolution of the World Heritage concept itself.

These criteria are explained in the Operational Guidelines for the Implementation of the World Heritage Convention which, besides the text of the Convention, is the main working tool on World Heritage.

The Organisation for Economic Co-operation and Development (OECD) produced  Mainstreaming Biodiversity for Sustainable Development for biodiversity policymakers and practitioners in developed and developing countries, as well as development co-operation agencies and other national ministries. The report highlights examples of good practice and remaining challenges in four key areas: mainstreaming biodiversity at national level; mainstreaming biodiversity in the agriculture, forestry, and fisheries sectors; development co-operation and biodiversity mainstreaming; and monitoring and evaluating biodiversity mainstreaming. Examples and insights are included from 16 predominantly megadiverse countries which span the full range from high-income to lower-income economies. The national level entry point for biodiversity mainstreaming is important and elements to encourage mainstreaming and its implementation in practice across relevant national plans and strategies.

The Group on Earth Biodiversity Observation Network (GEO BON) developed the concept of Essential Biodiversity Variables (EBVs) to advance the collection, sharing, and use of biodiversity information to aggregate, harmonise and interpret biodiversity observations collected by different methods such as in situ monitoring or remote sensing. EBVs can be visualised as biodiversity observations at one location over time, or in many locations, aggregated in a time series of maps. Essential variables to understand climate, biodiversity, and other environmental changes have already been developed (e.g. Essential Climate Variables, Essential Ocean Variables).

How to use

Details of the method, the EBVS already developed, and results are available at: https://geobon.org/ebvs/what-are-ebvs/

The Treaty was developed by FAO. The objectives of the Treaty are the conservation and sustainable use of all plant genetic resources for food security and agriculture, and the fair and equitable sharing of the benefits arising out of their use. The Treaty puts 64 of the most important crops that together account for 80% of the food derived from plants into an easily accessible global pool of genetic resources that is freely available to potential users in the Treaty’s ratifying nations for some uses. The Treaty ensures that access to genetic resources already protected by international property rights is consistent with international and national laws.

EICAT is the IUCN global standard for measuring the severity of environmental impacts caused by alien species. EICAT is a key tool for prioritising alien species that could lead to the most harmful environmental impacts, helping to make the best use of resources to prevent or limit their negative consequences. EICAT classifies alien species into one of eight categories (see figure) according to the severity of their impact on native species and whether the impact is reversible The EICAT Categories and Criteria provide a simple, objective, and transparent classification method. The EICAT Guidelines provide detailed assistance in the application of the categories and criteria.

EICAT can be applied at national, regional, and global levels. All global EICAT assessments are published on IUCN’s Global Invasive Species Database. The EICAT Authority is the governing body coordinating the EICAT assessment process and it is responsible for carrying out the majority of assessments and implementing the review process. The EICAT Authority is composed of experts on specific taxonomic groups or geographic regions.

A protected or conserved area that reaches the IUCN Green List Standard is certified and recognised as achieving ongoing results for people and nature in a fair and effective way. A site that gains ‘Green List’ status demonstrates: Respect: for the local community through fair and meaningful engagement of rights-holders and stakeholders; Design: planning that identifies the needs to secure  the important values of the area; Effective management: monitoring of the status of these important values; Successful conservation results: for nature and for people; Clear contribution: to climate change responses, health and well-being and other challenges. The seventeen criteria collectively describe the efforts needed to fully achieve the global Sustainability Standard and all must be achieved for a site to be green-listed. The indicators can be adapted to suit the local context. Any site can join, and work towards achieving verified success, and then attain the Standard or further improve.
