I'm curious if someone could explain the range data. Is the range data generated from iNat identifications or from an external source? Either way, it doesn't seem to align with data from papers which have analyzed the genetics of these two marten species:

\1. Implications of introgression for wildlife translocations: the case of North American martens, 2019. DOI: 10.1007/s10592-018-1120-5
\2. Reconciling molecules and morphology in North American Martes, 2018. DOI: 10.1093/jmammal/gyy140
\3. Historical biogeography sets the foundation for contemporary conservation of martens (genus Martes) in northwestern North America, 2017. DOI: 10.1093/jmammal/gyx047

All three papers appear to suggest that the range of Martes caurina in British Columbia is largely restricted to certain coastal islands and that in the Columbia Mountains (and perhaps in the Rockies) one finds hybrids of the two species; outside of those areas, it's probably Martes americana.

Hi, @murphyslab. I adapted the range maps from those available on Yale University's Map of Life (here are the pages for Martes caurina and Martes americana, respectively). The one for M. caurina was downloaded directly from MOP and I constructed the one for M. americana_ myself because of a download error, but I based it directly on what they had on their site, not primarily literature. These maps were also used in the Illustrated Checklist of the Mammals of the World (Burgin et al. 2020).

According to the literature cited by the MDD for Martes caurina, there should be significant more overlap between the two species in British Columbia than MOL's maps suggest. I'm not sure what their deriving their maps from.

I will contact them to find out what material they cited.

Thank you for the replies and for looking into this further, @bobby23 .

Also the Map of Life sounds super useful. I'm not an expert in any of the life sciences, so it's a new resource to me. If iNat isn't clear, I usually just go on GBIF to get an idea of range data.
