Wisconsin Phenological Society

The Wisconsin Phenological Society (WPS) is organized for the study of the relationship between the stages of plant growth and animal life and physical factors of the environment; particularly climate and weather. These natural phenomena serve as a basis for the determination of local seasons and plant climate zones, and are considered to integrate the effects of a number of climatic factors. The knowledge gained will promote better understanding of the timing of natural (phenological) events.

WPS invites citizen scientists like yourself to join the society and contribute your phenological observations.
