The richly-scented [6] flowers have a pure white, deeply four-lobed corolla, the lobes thread-like, 1.5 to 2.5 centimetres (0.59 to 0.98 in) long and 3 millimetres (0.12 in) broad; they are produced in drooping axillary panicles 10 to 25 centimetres (3.9 to 9.8 in) long when the leaves are half grown, in mid- to late May in New York City ...
In the United States, the forest cover by state and territory is estimated from tree-attributes using the basic statistics reported by the Forest Inventory and Analysis (FIA) program of the Forest Service. [2] Tree volumes and weights are not directly measured in the field, but computed from other variables that can be measured. [3] [4]

The rate of decrease can vary in different mountain chains, from 3.5 °F (1.9 °C) per 1,000 feet (300 m) of elevation gain in the dry mountains of the western United States, [17] to 1.4 °F (0.78 °C) per 1,000 feet (300 m) in the moister mountains of the eastern United States. [18]
When stocking, a tree's basal area is measured. The basal area is a cross-sectional area of the stump taken about 4.5 feet (1.4 m) above the ground. [7] The equation for calculating the basal area of trees in a stand is Basal Area = 0.005454 DBH 2, where DBH is the diameter of the tree at the aforementioned measuring height. [7]
Tree girth measurement diagram. Tree girth is a measurement of the circumference of tree trunk. It is one of the most ancient, quickest, and simplest of foresters' measures of size and records of growth of living and standing trees. The methods and equipment have been standardized differently in different countries.
