If a tree had no leaves...

could you tell what tree it was?


Trees in Winter
Post under development...more later...
In winter, deciduous trees have already lost their leaves. You remember the autumn foliage season, when the leaves fell, don't you? So, how can you tell trees in winter?

Surprisingly, witch hazel flowers in winter, so that one is easy to tell...but, others? But, especially on a warm winter day...when snow is melting, but, it's not yet spring... you might like to take students for a walk. In preparing lessons, you might consider a walk where you use a key to identify trees. Cornell has a booklet for children 8 to 12 that adults will also find helpful: http://srb.npaci.edu/cgi-bin/nsdl.cgi?uid=/2007-05-23T18:23:11Z/D6C24D0D88B737E70B034467BBB04500/treeswinter.pdf

Winter, well, that's when a "twig key" comes in handy.

A site that can help you learn the vocabulary of "twigs" is: http://www.epa.gov/superfund/students/clas_act/winter/dressup.htm

Branching patterns and bark are also useful for identification.

If you are more interested in computers than walks outside, but, still want to work on winter trees, try: branching and computers...
