What is phenology?
When the aspen trees change their colors, when the first snowflakes start to fall, when the osprey return to their nest, and when the flowers begin to bloom each year are all examples of seasonal changes. These changes are all around us. They can be studied by anyone, no matter how old you are or where you live.
Scientists around the world study phenology to learn more about plants and animals—as well as the land, air, and sea we all share. Phenology is also important for scientists that study the Earth’s climate and how it changes over time.
