Exported trees from USDA PLANTS database. Made no attempt to ensure taxa matched correctly on iNat, so the listing here is far from complete or accurate. Excludes hybrids and infraspecific taxa.

For example, the list I imported had 2953 species on it while the final list here only has 2334.

They also seem to define taxa that I would definitely call "shrubs" as "trees" (like Cephalanthus occidentalis)!
