"Phenology is the study of the annual cycles of plants and animals and how they respond to seasonal changes in their environment. For example, in botany phenology refers to the timing of flower emergence, sequence of bloom, fruiting, and leaf drop in autumn." 2

Phenology models can be used to help an endangered species by the planned removal of common competitors at a time when the reproductive cycle of the endangered species is least susceptible to damage.

Phenology models can document changing weather patterns.

Phenology models allow us to plant seeds at just the right time.

Phenology models move both the bee farmer and the migrant worker.

Phenology models can be used to eliminate dangerous pests by attacking with the least toxic yet most effective measure available at the time the pest is most susceptible.

Phenology: “Northern Saw-whet Owls begin migrating as deciduous foliage nears peak color and ends approximately 1 month after leaf fall.” 3

The length of daylight changes and we put names to patterns.
