Phenology and Climate

Ongoing

Help us understand how plants are responding to this year's seasons and longer-term changes in climate

How plants react to seasonal change has a big impact on the environment. Because plants are at the base of the food chain, anything that affects plants can impact other parts of the ecosystem. Phenology is important because it affects plants ability to produce fruits and seeds and food availability for other animals like birds and squirrels. It is important to humans because our food supply depends on plants blooming when pollinators are available. And, to scientists, changes in the timing of phenological events can be used as indicators of changing climates.

HELP ANSWER THIS RESEARCH QUESTION:

How is climate change affecting plant phenology?

Changes in phenological events can also have a significant impact on how we humans live our lives and interact with our environment on a daily basis. For example, the timing of when plants flower and fruit can affect our food supply and therefore our health. Pollen allergies can also be exacerbated by changes in growing conditions. People who are allergic to plant pollen will experience reactions to the changes in flowering times and the lengthening of the growing season.

From historical records and observations, we know that phenological events can vary from year to year. Ecosystems can recover from variation between years, but when these changes happen consistently over many years, the timing of events such as flowering, leafing, insect emergence, and allergies can impact how plants, animals, and humans are able to thrive in their environments.
