Phenology is the study of the timing of natural events – in particular, life cycle events such as leaf out, migration, flowering, or mating.  Since many of these events are tied to temperature, phenology can be a powerful way to study the potential effects of climate change.  We track phenology to discern the impact of climatic changes on the Walker Valley ecosystem using three different projects. Check them out!
