Phenology

Phenology is the study of the timing of natural events. Common examples include the date that migrating birds return, the first flower dates for plants, and the date on which a lake freezes in the autumn or opens in the spring. Phenological records help alert us about the events of nature and provide interesting comparisons between years and among different geographic regions. If recorded carefully and consistently, these records also have scientific value for understanding the interactions between organisms and their environment and for assessing the impacts of climate change. **National Phenology Network NPN **  [|**NPN PLANT LIST**]    [|American beech (Fagus grandifolia)] Andrew Miano    [|Box Elder (Acer negundo)] [|Black cherry (Prunus serotina)] [|Common lilac (Syringa vulgaris)] [|Dandelion (Taraxacum officinale)] [|Forsythia (Forsythia spp)] Jen Lennon [|Red maple (Acer rubrum)] Samantha Williams <span style="color: rgb(44,121,193); text-decoration: none;">[|Sugar maple (Acer saccharum)] Nick Manta <span style="color: rgb(44,121,193); text-decoration: none;">[|White oak (Quercus alba)] =  = <span style="color: rgb(85,26,139);">
