Great video. Good info in a concise manner. Now that I can pick out the traits of a twig, what’s a good resource to use those traits for identification?

Thank you so much! If you don't mind me asking. what part of the country or World are you in? I can better recommend plant identification books with that information :)

@@michelleh1722 I think "A Peterson Field Guide To Eastern Trees: Eastern United States and Canada, Including the Midwest" or the plant ID books released by the National Audubon society would be a good place to start. You'd want a plant identification field guide that says "eastern", "north eastern", "central", or "midwest" in the title. I also recommend you check out Alexis Nikole Nelson (@blackforager), since she is based in Columbus, Ohio. I hope this helps! :)
