Species-level data Species range maps were derived from BirdLife International and NatureServe50and the IUCN51. The threat data were from the IUCN Threats Classification Scheme (Version 3.2), which contains 11 primary threat classes and almost 50 subclasses52. In Red List assessments, assessors as...
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. Four qualities were sought in the design of the ...
meeting any one of these criteria qualifies a taxon for listing at that level of threat. Each species should be evaluated against all the criteria. The different criteria (A-E) are derived from a wide review aimed at detecting risk factors across the broad range of organisms and the diver...
The threat to the future of a vulnerable bird species has halted the Rs. 6,400-crore hydro power project in Tawang, Arunachal Pradesh. The species breeds on the Tibetan plateau and migrates to Tawang for the winter. The bird, most commonly found in China, is legally protected in Bhutan...
The Mediterranean Red List assessment is a review of the conservation status at regional level of approximately 6,000 species of animals and plants.

Using coarse instead of fine grain grid cells would have classified ten species in a lower Red List category. Compared with the previous Red List, nine species were classified in a lower and 12 in a higher threat category. In total, 218 1×1km2 grid cells were considered as (very) high...
We also investigated if the number of uses, PUD and PD predict palm threat level. Species covered by IUCN Red List have lower PUD and PD than expected by chance. At global scale, palms with higher extinction risk have lower number of uses, PUD and PD. However, whereas in Colombia least...
Since 1963 the International Union for Conservation of Nature (IUCN) Red List has provided the world with a credible and effective call to action for preventing species extinction. However, the criteria for assigning categories of threat (e.g. 'critically endangered,' 'endangered,' 'vulnerable')...
