Vertebrates on the brink as indicators of biological annihilation and the sixth mass extinction

The ongoing sixth mass species extinction is the result of the destruction of component populations leading to eventual extirpation of entire species. Populations and species extinctions have severe implications for society through the degradation of ecosystem services. Here we assess the extinction crisis from a different perspective. We examine 29,400 species of terrestrial vertebrates, and determine which are on the brink of extinction because they have fewer than 1,000 individuals. There are 515 species on the brink (1.7% of the evaluated vertebrates).

Runway to Extinction - Wildlife Trafficking in the Air Transport Sector

The findings in this report are not meant to represent the entirety of wildlife trafficking activity through the air transport sector, but are intended to showcase the patterns visible within the C4ADS Air Seizure Database, with the understanding that a different or more complete dataset may reflect different results. Each section of the report should be read with this in mind. Overall, Runway to Extinction finds wildlife trafficking to be global in scope, with trafficking attempts reported more and more frequently.
