September Happenings

Seasonal Update

September is a month of turnover. Summer residents are leaving Minnesota while birds that will carry us into fall and winter are arriving, all against a backdrop of rapidly changing vegetation and weather. What else can you expect this month?

For years, Minnesota naturalist and author Jim Gilbert recorded seasonal happenings in his phenology reports. Looking back at these reports, we can make educated guesses at what we can expect in the month ahead. Take a look at our archive of Jim Gilbert’s Phenology reports.
