3 November 2021:
There have been some major changes in Centennial Woods since my last visit on October 8th. Most notably, the weather was warm and summery the last time I went. This time, the temperature was around 40ยบ F. Most trees had become bare, and the few that still had leaves were sparse and yellow, red, orange, and brown. It was much quieter with far fewer birds and insects. The trails were also much more muddy because of recent heavy rainfall, and I noticed fewer ferns and smaller understory plants.
Despite these changes, there were still animal species inhabiting the landscape. I noticed many squirrels and some native bird species such as ravens. Holes in tree trunks also suggested the presence of woodpeckers.
