I developed this checklist after discussions in 2014 on the community forum. It is very much a work in progress (I plan to update it every 6-12 months) and is very largely based on the IUCN’s Red List. It isn’t perfect, but it might be the least imperfect list there is from a mammalwatcher’s point of view. Please send comments to me, or post them on the forum.
The spreadsheet lists changes made over time, as well as how my list differs from that of the IUCN’s.

Here is some interesting discussion on differing taxonomies that influenced the presentation of this list.
