I had the opportunity today to work in Wytham Woods, a heavily researched patch of woodland near Oxford. Continuous biology research and monitoring has been going on in Wytham Woods for more than sixty years, which allows for study of (relatively) long-term trends.
The variety of research done in Wytham Woods also means that the part of the woods that my class was working in was already spotted with data collection points, research shelters, and flagged trees. We added a few research markers of our own, and over the next few weeks, we'll be analyzing the biodiversity of various 25m by 25m plots of woodland. Eventually, it may be that every major organism in the woods is involved in one or more research projects. It's quite a site to see.
