Phenology is the study of how plants and animals are affected by the annual cycles of nature. Many of nature’s most interesting events can be linked to the weather. Predictable fluctuations in temperature, air pressure, and daylight prompt many plants and animals to change their behaviors and sometimes even their appearance. Since every species has its purpose, place and season - phenology can help us appreciate and understand a species’ role in its habitat. By tracking these phenology occurrences, we can begin to understand how events and species are inter-related and help piece together the fascinating mosaic of the seasons.
