Humans affect the forest in many ways.
The animals and plants of the forest feel even small changes in their community. If we can find out what is going on with the animals in a given area we can then have some grounds to measure the health of those ecosystems as they change over through time. Students will become linked person to person, in a way that demonstrates the interdependence of living creatures in a forest. Outside or in, you will need a large area. Groups of 10-30.
