This is a good question, and might warrant some further discussion. But due to the life histories of the various WCT populations (fluvial, adfluvial, resident), these natural barriers will still fragment the system (e.g., there might be an isolated population of resident WCT upstream of a falls, but the waterfall is still preventing any upstream migration).
I'm trying to remember how he handled this originally, but I think we already ignore natural barriers for accessibility/connectivity but don't change the barrier status in the underlying data?
This probably requires a bit of digging. The access model query is the same as the other species, with the exception that we do not discard natural barriers based on upstream observations. I think the tweaks to the connectivity status were in the reporting, but I do not see the Elk specific connectivity query in current files. It is probably in there somewhere.
Salmon and steelhead models do this. I think it makes sense for WCT - but should be confirmed by @nickw-CWF or other CWF modellers more familiar with the species.
At the moment this is moot, there are no barriers downstream of known habitat in ELKR.
