The International Union for Conservation of Nature (IUCN) Red List of Threatened Species was increasingly used during the 1980s to assess the conservation status of species for policy and planning purposes. This use stimulated the development of a new set of quantitative criteria for listing species...

Abstract Systematic assessments of species extinction risk at regular intervals are necessary for informing conservation action 1,2 . Ongoing developments in taxonomy, threatening processes and research further underscore the need for reassessment 3,4 . Here we report the findings of the second Glob...

The Red List Index uses information from the IUCN Red List to track trends in the projected overall extinction risk of sets of species. It has been widely recognised as an important component of the suite of indicators needed to measure progress towards the international target of significantly redu...

Stopping declines in biodiversity is critically important, but it is only a first step toward achieving more ambitious conservation goals. The absence of an objective and practical definition of species recovery that is applicable across taxonomic groups leads to inconsistent targets in recovery pla...

Recognizing the imperative to evaluate species recovery and conservation impact, in 2012 the International Union for Conservation of Nature (IUCN) called for development of a "Green List of Species" (now the IUCN Green Status of Species). A draft Green Status framework for assessing species' progres...

Biodiversity loss is a major global challenge and minimizing extinction rates is the goal of several multilateral environmental agreements. Policy decisions require comprehensive, spatially explicit information on species' distributions and threats. We present an analysis of the conservation status ...

We assessed the threatened status of 163 Central Asian vertebrates using the IUCN Red List Criteria (Version 3.1) at the national and regional levels, and compared these assessments to the global assessments given in the IUCN 2002 Red List. We thus compared threat status at three spatial scales; nat...

We were pleased to see the attention afforded bioinformatics for biodiversity in Science 's special issue on the topic (29 Sept., pp. [2305][1]-[2314][2]). It is essential that informatics technology be devoted to increasing our understanding of Earth's taxonomic diversity and to developing means to

The assessment region - the Arabian Peninsula - contains a wide diversity of sand and gravel deserts, mountains, coastal and offshore habitats and sparse wetlands. It also contains a diverse mammal fauna which comprises a mix of Arabian endemics, species with affinities to the Horn of Africa and Sah...

THE CONSERVATION STATUS OF ALOE IN SOUTH AFRICA: AN UPDATED SYNOPSIS

Neil A. Cox, James Westrip, Philip Bowles, Craig Hilton‐Taylor et al.

Abstract Soil biodiversity is crucial to the maintenance of multiple critical ecosystem functions and services. However, remarkably little is known about the conservation status of most soil-dependent species. To better understand the current situation, we determined the number of soil-dependent spe...
