THE IOWA PHENOLOGY CALENDAR
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.
ASK ABOUT CALENDARS BY VISITING THE Contact Leeward PAGE AND SENDING A MESSAGE.
Consider calendars as:
* Holiday and birthday gifts.
* Prizes and gifts to employees or another special group
of people, perhaps students or environmental and
science teachers.
* Your personal guide to the outdoors, at home and at
work.
*"Swag" for conferences, employee parties, and other events.
In addition, if you are interested in using the calendar as a fundraiser for your business or organization, send a message through the Contact Leeward page.

phenology
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.
