This heading is only a tiny bit less vague than "Everything," which was my original choice. Natural History comprises, well all that is or was once alive, including plants, animals, fossils, fossil fuels, fossorial moles, ossified old guys, and fungi. It's inevitable these categories overlap here and there. For example, emerald ash borers belong in the tree category (if not in actual trees), and in the invasive-species section. Very few facts have been made up. Please share your anecdotes, or excoriate me for glaring errors you find, by emailing me. Thanks. I hope you find something you enjoy.
