Scientists have documented that climate change is affecting the timing of spring warm-up and fall cool down. These changes alter the timing of plant life stages (such as bud break, flowering and leaf fall) or what is called “phenology.” At the national level, many scientists tracking phenological changes have begun to collaborate as part of the USA National Phenology Network (USA-NPN). In support of this national effort, NSRC researchers initiated a more focused regional network in the northeastern United States and eastern Canada called the Northeast Regional Phenology Network (NE-RPN) at a November 2007 workshop that included northeastern researchers in forest ecology and remote sensing, leaders of “citizen science” groups, and members of the USA-NPN.
