The Maryland Envirothon
Forestry 2010 Resource Site
Tree Identification

This is an online study guide for advisors and students participating in the Maryland State Envirothon competition. It is not inclusive of all content you may need to know for the state competition. Web sites provided are for reference only and may not be exactly what students are tested on.

Introduction:

Because Maryland has five distinct physiographic provinces from the Coastal Plain to the Allegheny Plateau, our state features a great diversity of tree species, which makes the tree identification station of the Envirothon a challenge!

During the competition, your team must identify 10 or 15 species of trees by their correct common name. Professional foresters have completed college courses in dendrology, or the science of tree identification, and have to identify literally hundreds of species of trees and shrubs by both their common and scientific names.

When identifying trees, nearly all of your senses may be utilized (except hearing!), to examine the entire tree. Here are several characteristics to look for when identifying tree species:

There are many other tree identification tips, often used to distinguish one species of tree from another (for example: red oaks have pointed lobes, while white oaks have rounded lobes), and these are learned through experience and training from your teacher or forestry resource professional.

Special Thanks…

To the Virginia Tech Forestry Department for the use of their excellent Tree Identification Fact Sheets. The following species are trees you should be familiar with for the tree identification station of the Envirothon Forestry competition. Trees marked with an asterisk (*) are species commonly found in Frederick County, Maryland, site of the 2003 Canon Envirothon, but may also be found throughout the state.
