Which is the percentage of threatened species of birds, cactus, mammals, and other taxonomic groups?

Discover what the IUCN Red Listthe most authoritative source of information about the conservation status of plant and animal species of the world– tells us about this.

Illegal Wildlife trafficking produces overexploitation*, which is currently recognized as the second cause of extinction in the world. In hope of contributing with the protection from illegal wildlife trafficking of some of the threatened species, Barcode of Wildlife Project is creating DNA barcodes that might help to make easier the detection of illegal wildlife trafficking in the future; you can also know some of the Mexican participating species in the Project bellow!
*Overexploitation occurs when more individuals than the ones that can reproduce in the wild are extracted by overfishing, overharvesting, etc. This leads to a diminishment in population growth, and can produce species extinction.

Note to the reader: according to the IUCN, extinction risk has been evaluated for less than 5% of the world's described species. The following data has been extracted from the IUCN Red List of Threatened Species.

63% of cycads are threatened.

41% of amphibian species are threatened.
Some of the amphibians that are participating in Barcode of Wildlife Project are:
Axolotl (Ambystoma mexicanum)
