“The best scientists and explorers have the attributes of kids! They ask questions and have a sense of wonder. They have curiosity. ‘Who, what, where, why, when and how!’ They never stop asking questions, and I never stop asking questions, just like a five year old.” – Sylvia Earle
What is Phenology?
Phenology is nature’s calendar—when cherry trees bloom, when a robin builds its nest and when leaves turn color in the fall.
Phenology is a key component of life on earth. Many birds time their nesting so that eggs hatch when insects are available to feed nestlings. Likewise, insect emergence is often synchronized with leaf out in host plants. For people, earlier flowering means earlier allergies. Farmers and gardeners need to know the schedule of plant and insect development to decide when to apply fertilizers and pesticides and when to plant to avoid frosts. Phenology influences the abundance and distribution of organisms, ecosystem services, food webs, and global cycles of water and carbon. In turn, phenology may be altered by changes in temperature and precipitation.
Changes in phenological events like flowering and animal migration are among the most sensitive biological responses to climate change. Across the world, many spring events are occurring earlier—and fall events are happening later—than they did in the past. However, not all species are changing at the same rate or direction, leading to mismatches. How plants and animals respond can help us predict whether their populations will grow or shrink – making phenology a “leading indicator” of climate change impacts.

How much does a Phenology Trail cost to implement?
Indiana Phenology does not charge for its services and can help you find grants and develop a fundraising program to cover any costs that may be associated with a Phenology Trail.
Every Trail is tailored to the needs and desires of the people who manage or own the property, so costs may vary. It's possible to start a Trail at no cost with an existing volunteer base that is knowledgeable of the area.
