iNat people might be interested in this analysis, which was done first to answer the question “How complete is the iNat plant species list for the Devils Slide Trail?”.
I then analyzed the iNat points for the trail, separating them into species confined to wet areas and the other species.
Analysis of iNat Observations of Plants of the Devils Slide Trail
The graphs of the observation locations with the drainage overlay is quite interesting, particularly how plotting the wet area species shows them following the drainages and highlights the out of place species.
I’ve used comparative distribution maps on Inaturalist before to look for out of place observation (example using Cyathodes in Tasmania). Your approach is quite interesting since it highlights geographical features more clearly
I’m writing a report on a survey I’ve done at a Tip in Tasmania (2361 observations so far, 250+ species including subsp.)
It was wonderful to have so many iNat obs from that trail to analyze. Good luck in your analysis!
