The study of recurring plant and animal life cycle events is phenology. It is the calendar of nature. This includes when plants flower, when birds migrate and when crops mature. Phenology is relevant to interactions between organisms, seasonal timing and large-scale cycles of water and carbon. Phenology is important to us for many reasons. Farmers need to know when to plant and harvest crops and when to expect pests to emerge. Resource managers use it to monitor and predict drought and assess fire risk. Vacationers want to know when the best fall colors will be or when the wildflower blooms will peak. Timing varies but we can discern patterns.
The USA National Phenology Network monitors the influence of climate on the phenology of plants, animals and landscapes. They encourage people to observe phenological events such as flowering, migrations and egg laying. The Phenology Network provides a place to enter, store and share these observations, which are then compiled and analyzed nationwide. Participants range from individual observers in their own backyards to professional scientists monitoring long-term plots. My husband and I monitor leafing and flowering of lilacs, a key species in the program.
These observations support a wide range of decisions made routinely by citizens, managers, scientists and others. This includes decisions related to allergies, wildfires, pest control, and water management.
I urge you to participate. The National Phenology Network has many public, private and citizen partners. It is a great way to become involved in a nation-wide effort to better understand our environment. All this information and much more is available at the National Phenology website, to which there is a link from our Wild About Utah website.
