Assessing Extinction Risk for Global Shark Trends

The IUCN Red List of Threatened Species is recognized as the most comprehensive, objective, global approach for evaluating the conservation status of species. Individual species as assessed against the IUCN Red List Categories and Criteria to determine their relative risk of extinction (see Categories overview below), with the aim of highlighting those species which are facing an elevated risk of global extinction (those assessed in the threatened categories: Critically Endangered, Endangered, or Vulnerable). There are currently 1,091 published chondrichthyan assessments on the IUCN Red List, largely the result of nearly 20 years of Red Listing effort by the SSG.

It's all in the Name:​ Shark Systematics and the IUCN Red List

The Ever-changing Nature of Chondrichthyan Systematic

Chondrichthyan systematics is an ever-changing and ever-advancing field. Names change, new species are described, species are “sunk” - sometimes the result of a “lump” (two or more previously recognised species are shown to in fact be the same species) - and old names are resurrected. Keeping up with these changes can be daunting for the non-taxonomist, but is essential in everything we do as SSG members. Indeed, taxonomy is a foundation of the life sciences. This field classifies and arranges the taxa we work on, from the higher level, to the species level. Knowing which species we are studying, managing, or conserving is the very foundation of the SSG’s mission.​

A New Era for the IUCN SSC Shark Specialist Group

5/12/2020

 
​Nicholas K. Dulvy | SSG Co-Chair

​After nearly two decades of piecing together the global Red List assessments for all chondrichthyans, we are now in a position to take a much more strategic approach to complete the first full reassessment by 2020. In recent years, we have managed to keep Red List Assessments ticking along on a shoestring budget to undertake this vital task, with considerable efforts of volunteer members and staff. Part of the challenge has been the increasing scale of the backroom work required to review assessments and prepare them to the consistency standards of the IUCN Red List.

Introduction to the Global Shark Trends Project 2018-2020

1/12/2020

 
Picture
Assessing and reassessing the extinction risk of chondrichthyan species for the IUCN Red List of Threatened Species is one of the core activities of the IUCN SSC Shark Specialist Group (SSG). To undertake this activity, the SSG has commenced the Global Shark Trends Project (GSTP), a collaboration between Simon Fraser University, Charles Darwin University, James Cook University, and the Georgia Aquarium, funded through the Shark Conservation Fund.

​Tonight at the Sharks International conference, the Shark Specialist Group (SSG) of the International Union for Conservation of Nature (IUCN) reports on progress and new priorities associated with their Global Strategy to save the sawfishes, the world’s largest and most threatened rays. The expert update highlights the plight of Brazil’s Critically Endangered Largetooth Sawfish, and lays out clear steps for preventing extinction and restoring the population.
