The Forestry guide will be released during ScioCamp 2022.
Getting Started
Someone asked me if I could advise them on which tree guide to purchase for next year. I have a few suggestions (in no particular order):
1. National Audubon Society Trees of North America
Pros: Very good pictures, recognized by most experts
Cons: you might have to buy two of them, one for the west and one for the east. That will take up your two total field guides allotted for the event and might make it harder for you to find things.
2. Trees: DK Handbook, by Allen J. Coombes
Pros: I actually have read this one and like most DK books it makes everything pretty simple to understand. It does have a guide at the beginning with ID tips which is helpful too. Its a nice book.
Cons: Has less tree species than the Audubon one
3. The Illustrated Encyclopedia of Trees: Second Edition, by David More and John White
Pros: This is the book that got me into trees. Illustrations are beautiful and the information is very detailed. Covers around 2,000 species and is overall a very nice book. You can tell a lot of effort was invested into it's creation.
Cons: Is bigger than my Chemistry textbook and weighs more than the Bible, so I don't know if you can use it as a field guide. Species are categorized slightly randomly so its hard to find things. Also it only has illustrations and no actual pictures so might be hard for ID. Covers trees from all over the world, not just North America so you probably can't use more than half of it for the event. I would just keep it around for aesthetic purposes and information.
4. The Sibley Guide to Trees, by David Allen Sibley
pros: good leaf illustrations, 600 species
Cons: doesn't often show tree silhouette, uses imperial system and not metric system, illustrations are inconsistent, does not have a glossary/key
If I have read the book, the information above is my own opinion of the book and whether I think it is useful to you or not. If not then the rating is based off of Amazon reviews. Choose whatever you'd like, it will probably benefit you more than not having a field guide to work with.
I personally do not own any of these because I am lacking in money and a credit card and am unable to buy them off of Amazon T-T so I have to comb my school and local libraries for these and end up keeping them well past their return dates. Unfortunately my school is closed for the summer and made me return the DK guide I had, so for this course I am relying off of Google and other books that I am fortunate to own.
