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.

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.

What better way to become familiar with the natural world around you than have a calendar with the dates when things are happening? Photos of Iowa's plants and animals? And more?

 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.

Many cycles already are familiar, making you and most other humans students of phenology, even if you didn't know that. We are aware of daily or diurnal changes, seasons, bird migration, the flowering and seeding of plants, and other rhythms.
