Dear Ximevelez and Manola,
Thanks for your posts about the red panda's taxonomy. The EDGE list was published in January 2007, with the taxonomy based on the mammal supertree (published later in 2007) and the threat assessment based on the IUCN Red List.
Various aspects of the taxonomy and phylogeny, and many of the Red List assessments have since been re-evaluated or updated, and this additional information means that the current list is now out of date in places. We are currently working to incorporate these into the EDGE list, to produce an updated version and hope to present this on the website soon. We expect that there will be some interesting changes to the Top 100 EDGE mammals list!
