THE IOWA PHENOLOGY CALENDAR
Beginning with the 2018 issue, the Raccoon River Watershed Phenology Calendar was renamed the IOWA PHENOLOGY CALENDAR. This change reflects two important trends: increasingly the audience for the calendar lies in other watersheds, and my travels and photographic reach extend across the state.
The information in the calendar applies to most of the state, along with adjacent south central Minnesota, southwestern Wisconsin, western and northwestern Illinois, and far northern Missouri. In my travels, I've noticed some differences in the timing of plant flowering and other happenings, but with regular use you'll figure out the local timing pretty easily.

Below you'll find more on phenology, and there are some photo selections from the 2019 calendar.
Phenology is the study of cycles and patterns in ecosystems. In the broadest sense, it is the transfer of the sun's energy through natural rhythms and life cycles. Usually the focus is on life forms and the seasonal changes they experience, but these account for broader cycles, such as the exchange of water between air and surface.
