The IUCN Red List of Ecosystems: motivations, challenges, and applications [PDF]

Conservation Letters, 2015
In response to growing demand for ecosystem-level risk assessment in biodiversity conservation, and rapid proliferation of locally tailored protocols, the IUCN recently endorsed new Red List criteria as a global standard for ecosystem risk assessment ...

Ambiguity in guideline definitions introduces assessor bias and influences consistency in IUCN Red List status assessments

Frontiers in Ecology and Evolution, 2015
The IUCN Red List is the most widely used tool to measure extinction risk and report biodiversity trends. Accurate and standardised conservation status assessments for the IUCN Red List are limited by a lack of adequate information; and need consistent ...

A method for making Red List assessments with herbarium data and distribution models for species‐rich plant taxa: Lessons from the Neotropical genus Guatteria (Annonaceae)

Plants, People, Planet, 2023
Societal Impact Statement Despite its importance, biodiversity is declining rapidly. To adequately prioritise conservation efforts, we need to know how threatened species actually are.

Using Red List Indices to monitor extinction risk at national scales

Conservation Science and Practice, 2023
The Red List Index (RLI) measures change in the aggregate extinction risk of species. It is a key indicator for tracking progress toward nine of the Aichi and many proposed post‐2020 Global Biodiversity Framework Targets.

Global Trends in the Status of Bird and Mammal Pollinators [PDF]

, 2015
Biodiversity is declining, with direct and indirect effects on ecosystem func-tions and services that are poorly quantified. Here, we develop the first globalassessment of trends in pollinators, focusing on pollinating birds and mam-mals.
