Each location as described above (1B, 6T, etc) is a specific point along the weekly watershed rounds route which is permanently marked. Visible from each location are three dominant or codominant trees of each of the three species: sugar maple, yellow birch, and beech. These individual trees are permanently marked on the side toward the "location" mark. When possible, their crowns are visible from the location itself to minimize the amount of moving around that is necessary. For each tree at each location, and each week, one number is recorded in spring, and one in autumn. Observations are not needed in winter or in summer unless insect attack causes premature senescence or leaffall.

Routine observations of phenology at HBEF began in the spring of 1989. The objective of the observations is to provide repeatable, quantified phenology data in a way that takes little time. Observations are made once a week during the spring and fall.

Eight locations have been established for observations (described above). After three years these may be reduced in number if timing of events differs consistently among locations.*DECIMAL INTERPOLATION BETWEEN CODED TABLE VALUES IS ALLOWED, E.G. 2.2, 3.5*. The data is physically located at the USDA Forest Service, Durham, NH and was last updated on June 4, 2001.
