Planting more trees may cause the stand to become overstocked, and it will not have the maximum growth potential. When there is a very understocked stand, there are two options for helping the stand. Either plant new trees in the stand as an underplant or clearcut the stand and restart by planting all new trees. [6] If there is a fully stocked ...
Spring in temperate deciduous forests is a period of ground vegetation and seasonal herb growth, a process that starts early in the season before trees have regrown their leaves and when ample sunlight is available. Once a suitable temperature is reached in mid- to late spring, budding and flowering of tall deciduous trees also begins.

The above equation is an expression for computing the stand density index from the number of trees per acre and the diameter of the tree of average basal area. Assume that a stand with basal area of 150 square feet (14 m 2) and 400 trees per acre is measured. The dbh of the tree of average basal area D is:
The spring diet of the blue grouse features Douglas-fir needles prominently. [13] The leaves are also used by the woolly conifer aphid Adelges cooleyi; this 0.5 mm-long sap-sucking insect is conspicuous on the undersides of the leaves by the small white "fluff spots" of protective wax that it produces. It is often present in large numbers, and ...
Three forest stands Stand dynamics stages during succession.. A forest stand is a contiguous community of trees sufficiently uniform in composition, structure, age, size, class, distribution, spatial arrangement, condition, or location on a site of uniform quality to distinguish it from adjacent communities.
The leaves are needle-like, in pairs, 5–10 cm (2.0–3.9 in) long, and its cones are 3–8 cm (1.2–3.1 in) long. [ 8 ] Over much of its range, it is fire-adapted to stand-replacing wildfires , with the cones remaining closed for many years ( clausa = closed), until a natural forest fire kills the mature trees and opens the cones.
Fagus grandifolia is a large deciduous tree [6] growing to 16–35 metres (52–115 feet) tall, [7] with smooth, silver-gray bark.The leaves are dark green, simple and sparsely-toothed with small teeth that terminate each vein, 6–12 centimetres (2 + 1 ⁄ 4 – 4 + 3 ⁄ 4 inches) long (rarely 15 cm or 6 in), with a short petiole.
