Conifers have leaves that are green needles. Most keep their green needles all year long, except tamaracks/larch. Conifers have cones. Female cones carry the seeds. Male cones release pollen. At certain times each year, pollen is released and sent by the wind to find the seeds. The seed cones are pollinated producing fertile seeds. When the cones are dropped or harvested by animals, seeds dropped into the soil produce new conifers.

Activity - Identifing Trees:

We have supplied a 1-page Dichotomous Key below to help you identify the conifer trees in your schoolyard.

Dichotomous keys are easy to use after some practice. Bring your printed key out into the schoolyard and choose a tree to identify. Note that each step of the key usually has two choices. After identifying the trait, move onto the next step until you reach the name of your tree.

If you reach a step with vocabulary you do not know, take a moment to look up the word before moving on. Once you are comfortable identifying trees, make a map of all the trees in your schoolyard.
