hey greg,
the thing that's help me the most in tree i.d.
is visiting the local botanical gardens and checking
out the specimens there. you really get to see some
established trees that way. you can study a book all
day but nothing compares to getting up close and
personal w/ these beauties. the heathcoat botanical
gardens in ft. pierce and the mc kee botanical
gardens in vero beach are very nice. take a day and
enjoy yourself and you never know.....you might learn
something
peace out,
budroe
The National Audobon Society publishes some regional guide books to trees and plants that have full color photos etc. I can find the ones pertinent to my area at Barnes & Noble. My favorite tree ID book isThomas S. Elias' Field Guide To North American Trees. No color pics but excellent descriptions and drawings. The tree distribution maps seem to be quite accurate.
Gilman's book is good. Also, Urban Trees for Florida by the Florida Department of Agriculture and Consumer Services, Division of Forestry. Not sure if its still available. I got it free from the extension service back in the '80's.
