Seasonal Variation in Plants

By Cale Mitzel

Location & Time - Farm in Wrightsville- 3 acres of woods- Quadrants located in woods- Most pictures taken between Oct 28

and Nov 18- Observations made on Saturdays and

Tuesdays

- 3 quadrants of 1 sq meter each- Measure population density - Observe and explain seasonal

variation in plants

Project Idea

Seasonal Variation- Physical changes in an organism due

to seasons changing- Many plants die- Most trees lose leaves and grow them

back in the Spring in colder climates
