Tracking Phenological Events

Phenology is the study of the seasonal timing of life cycle events. One studies phenology when recording the date a certain plant grows, a tree’s leaves emerge, an insect hatches, or a migratory bird appears on its nesting grounds. Factors such as daylength, temperature, and rainfall influence the dates on which events occur each year.

Energy from the sun is increasing, temperatures are rising, ice is melting, and plant growth is beginning. Journey North observers are sharing cyclic, phenological events of flora and fauna that indicate the changing of the seasons in their areas.
