Heads up: Some or all of the identifications affected by this split may have been replaced with identifications of Alces alces. This happens when we can't automatically assign an identification to one of the output taxa. Review identifications of Alces alces americanus 852463

Taxonomic Split 112134 (Committed on 28-07-2022)

Various authorities recognize different subspecies for Alces alces for different reasons, but for the sake of simplicity and to recognize the preferences of the iNaturalist community to acknowledge subspecific taxa for the moose in North America, this taxon change shifts those recognized in the current IUCN Red List Assessment (Hundertmark, 2016).

Most recent phylogenetic work on Alces alces is aimed at determining if it represents one or two species, but there has been work done that support the traditional subspecific designations at least in North America (Hundertmark et al. 2003).

split into


@loarie there seem to be significant issues that occurred when I committed this swap. The input was de-activated but none of the inputs were activated.

I think I fixed the issue. One of the inputs was assigned to an inactive parent of the same name (Alces alces) and I overlooked it.

ok great

While the split roughly restores where the subspecies should be by region, it seems to have overlooked Cape Breton, as per this part of the Nova Scotia Department of Natural Resources story about the Cape Breton moose that I quoted from in my comment on the merge in 2019:

"The mainland moose and the Cape Breton moose are two separate sub-species. On the mainland, the moose are Alces americana and in Cape Breton the species is Alces andersonii. The original indigenous population of Alces americana in Cape Breton was extirpated in the late 1800's - early 1900's. The cause of this extirpation remains unknown. The current population in Cape Breton started from the introduction of 18 Alces andersonii moose from Alberta in 1947 and 1948. The moose from the mainland are native to eastern North America."


Could the Cape Breton moose please be put back to A. a. andersoni as they were back in 2019?

Please see http://www.accdc.com/webranks/NSvert.htm ranks for NS which supports the DNR story on their website (sorry about the poor formatting of my copy-and-paste from the table ... it looks better in the table at the link).

The issue I was trying to address is the Endangered status of the mainland Nova Scotia moose which are A. a. americana. If you don't distinguish the small but healthy and stable population of introduced A. a. andersoni in Cape Breton from the mainland NS moose, you don't get a clear picture of the plight the mainland moose are in.

@benarmstrong I have adjusted the atlases for these subspecies so that Cape Breton is included with Alces alces andersoni and excluded from A. a. americana. I committed a new taxon change here and I believe this should fix the issue.

Great! I left a comment on the new split but probably should've put it here to thank you for your efforts. I've been able to convey this good news back to the WRWEO board, as the iNat data is increasingly important when talking to the public about species on the land we help steward.

Happy to hear it! Please let me know if there are any other issues concerning moose or any other mammal taxa on the site.
