Phenology Trail

More Tours

Phenology is the study of the timing of life cycle events in plants and animals, which can be affected by variations in climate. Denver Botanic Gardens, along with the USA-National Phenology Network (USA-NPN), has created a Phenology Trail for collecting phenology data and learning about plants. These data can be submitted to the national database at USA-NPN, where they are available to all and used by scientists to study how plant phenology is affected by climate change.

This tour travels the Phenology Walk at York Street, one of three Phenology Walks on the Phenology Trail. (The other two are at our Chatfield and Mt. Goliath locations, with more to be added in coming years.)
