Might consider adding checkboxes for Bats and Hummingbirds (and maybe Other Birds?) in the Pollinators field.
I vote for an actual range in the pH field.
I'd prefer:
In Water
Wet
Wet Mesic
Mesic
Dry Mesic
Dry
checkboxes in the Water Needs field, but can understand why you might not want to go that direction.
Growth rate might be problematic because it's a relative measure that depends greatly on what you are measuring it against. Red oak is a relatively slow growing tree, compared to a cottonwood, but pretty fast compared to a bur oak.
