This past Saturday I took a walk in Centennial Woods and visited my Phenology site. From the first time I visited and to now, I have definitely noticed changes. The leaves have changed colors because the season has transitioned to fall, so there are colorful leaves on trees and on the ground. I have seen holes in trees that I can assume were from birds or bugs. There were white mushrooms growing on tree stumps, and leaves decomposing on the ground.
