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
