Researchers review site maps and plans
Phenology Research Field Work 2011
Phenology is the study of the timing of natural phenomena, especially in relation to climate. At the Andrews Forest, scientists have been studying the timing of bud break and flowering of plants, and relating that timing, across years, to the ongoing, long-term climate records at the site.
