AY Honors/Trees/Answer Key

1. Describe the ways in which trees and shrubs differ.

Trees are generally taller than shrubs and have a main trunk from which all the secondary branches grow. Shrubs are generally shorter and may have multiple stems rather than a single trunk. Some plants can be considered either shrubs or trees depending on their growing conditions, so the division should not be considered exact.

2. Collect and identify typical leaves from 15 different species of trees. Spread neatly, press dry, mount, and label in a suitable notebook or on uniform-size sheets of paper.

5. Describe the importance of forest conservation in your area.

Properly managed, forests are a renewable resource. In order to ensure a continuous supply of forest products (such as lumber), forests must be properly cut and replanted. Forests also serve as an important habitat for several species, both animal and plant. When plants lose their habitat they simply die. When animals lose their habitat, some will die and others will move into other areas - notably, areas where humans live. This promotes undesirable encounters between potentially dangerous animals and humans, with the animal invariably getting the short end of the stick.
