Back in the day when I taught dendrology courses, one part was species ID.
Maybe 100 species of herbaceous plants, about 80 species of shrubs and trees, including some introduced species.
A contractor supplied fresh (to be frozen) specimens of everything.
Plus, we had a very thorough herbarium of pressed and identified plants.
Plants are like people in the variation so there must have been a dozen cards for each.
I suggest that bushcrafters owe it to themselves to make a plant collection, figure out the ID and note those details on the card.
Make a plant press or three. You will need more newspapers and cardboard than you ever imagined.
Make up something to use as a "vasculum." Press, vasculum, note cards = go for a walk and don't forget the attached roots, please.
Stop for a brew up on whatever clever little stove you have, empty the vasculum, load the press and move on.
Grouse hunting in the autumn, we're still plucking things we don't recognize or have had the luxury of forgetting.
