CASE STUDY New Hampshire: Webcams in Forest The Hubbard Brook Experimental Forest (HBEF), located in the White Mountain National Forest of central New Hampshire, was established in 1955 by the USDA Forest Service. The Forest Service Northern Research Station has used the HBEF to help pio- neer the small watershed technique as a method of studying ecosystem processes, including tree phenology. In 1989, the Forest Service established observational phenology plots in the HBEF. Each year, they document sea- sonal timing of leaf out and leaf fall at the experimental forest using routine observations of tree phenology. They designed a phenology index, and they document spatial and annual differenc - es in leaf emergence and senescence. The remote phenology plots in the HBEF are su
