This is a quick exploratory analysis of the OSC herbarium.
I downloaded the OSC Vascular Plants native dataset from pnwherbaria.org. Interestingly, this dataset actually included mosses, so I filtered those out (their sampling was quite spotty). I also filtered records to include only those with relatively accurate locations, IDed to species, and with at least the year recorded.
That left me with about 111,000 specimens.
For comparison, I pulled all vascular plant data for Oregon from iNaturalist, excluding cultivated records.
