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 Budburst, a project of Chicago Botanic Gardens, has created a Phenology Trail for collecting phenology data and learning about plants. These data can be submitted to national databases via Budburst or 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 Trail 1 of the Phenology Walk at York Street. For Trail 2 at York Street visit Trail 2.
