Recording trees and plants at Heartwood Forest

Phenology, the science of recording natural regularly occurring events, already provides some of the longest written biological records in Britain.

If we continue to collect this valuable information on seasonal occurrences we will be able to demonstrate how climate change is affecting our wildlife habitats.

Volunteers from Hertfordshire Natural History Society and the Woodland Trust have set up a Monitoring Group, co-chaired by Ken Smith and Brian Legg to keep track of the changes, so far they've recorded a great variety of species.
