Coalition to Preserve and Grow

My science class has to go to a forest preserve tomorrow to collect data of our own group’s choosing. Our group has been undecided as to what data we should collect. Any suggestions/ideas?
If it helps, we’re a senior class, there are invasive species at the forest preserve, and we’re going to two different sites. Also, it doesn’t matter if the data is sophisticated or not.

I would suggest that each of you note everything you can about flora, fauna, terrain, weather, amount of light and water, etc. for each of the sites. If your teacher has mentioned invasive species, note all you can about them. Then compare notes and brainstorm for findings. Good luck!
