This is a very nicely done key, and includes a large
number of trees. Pictures at each step are very clear.
Unfortunately, it asks some very detailed questions
which you may well not know the answers to ... like "what shape are the
young buds" or "what color are the flowers in summer?".
A very good guide, with lots of information easily at
hand. Pictures are a little smaller than in some, and the
whole-tree illustrations are often not very clear. At each step
of the key, you can click on a link to learn more about the item being
requested.
After collecting all of your clues, you should
use our leaf key to verify the tree species you are
identifying. It also contains links to detailed ...

A fine key, very interactive with well done pictures --
illustrations highlight the choices.
At the end of the key, it presents a collection of the
possibilities, along with a clear picture of each; you can then
click on that picture to be taken to a full page of info about the tree.
Trees are from Virginia; close to what we have
here, but not exactly the same set, will be missing some things and
will have some that don't exist here.

An excellent key, pictures are very
clear and there's good explanation about the choices. Also
provides a bunhc of "mystery trees" you can select to practice with.
Downside: this is from Wisconsin, so the set of
trees is a little different that what we have here: will be missing
some things and will have some that don't exist here.

Seems very nice. Good set of choices, nicely
illustrated: sometimes by photos, sometimes by drawings.
Questions a little more detailed than average, but mostly seem
ok. Very good information & pictures at the end, where the
specific tree is described fully.

and twig characteristics for tree identification. ...

Not recommended. Guide presented much as is done
on paper: question (text) and number of next step (which you
click on). Questions lack pictures -- you can click on them to
get more info, but even this is rather limited, sometimes
confusing. For example, "broad leaf" shows a number of different
leaf shapes, but none are lobed like maple or oak.
Also, from South Carolina. Likely to be somewhat
different than Mass.

A very clean and easy to use guide. Pictures are
mainly sketches -- with very good detail. In addition, the
particular feature being checked is highlighted in green (for example,
the veins).
These trees are from Ohio; should be mostly
similar. A wide collection of trees are keyed.
