This is a comprehensive look at the red spruce tree, what it looks like, its importance to wildlife, how it is used, how it reproduces, and where they usually grow. Picea rubens red spruce trees are also commonly referred to as the yellow spruce, the west virginia spruce, the eastern spruce, or the he-balsam spruce.
Red spruce seedlings have a root system of finely branched rootlets and no strong laterals; they depend entirely on the humus for nutrients and water site characteristics red spruce grows in climates with cool, moist summers and cold winters in the northeastern united states, the mean annual precipitation ranges from 36 to 52 inches (910-1,320 mm) and is often higher in the mountainous terrain where red spruce occurs, due to fog drip.
A spruce is a tree of the genus picea /paɪˈsiːə/, a genus of about 35 species of coniferous evergreen trees in the family pinaceae, found in the northern temperate and boreal regions of the earth. Spruces are large trees, from about 20–60 m tall when mature, and have whorled branches and conical form. They can be distinguished from other members of the pine family by their needles, which are four-sided and attached singly to small.
Sitka spruce is the tallest species of spruce that can reach 300 feet in height. Tree grows very fast, from 6 to 11 inches per season, even though some species can grow 60 inches per year. Spruce has needle-like leaves that are spirally arranged on the branches.
While the structure of wood in different softwoods is fairly similar, spruce does exhibit some distinguishing characteristics. Like pines and larches, spruce wood has resin canals, which supply resin to seal up wounds in the tree's bark. Unlike pines and like larches, spruce wood has small resin canals.
Spruce is light and soft, but nevertheless has good strength and elasticity properties for its relatively light weight. It is not very susceptible to shrinkage and when dried remains stable. Its low natural durability can be compensated for by applying a protective coat of paint.
Red spruce is a evergreen, coniferous species of tree which, under optimal conditions, will grow to mature heights of 60 to 130 feet (18 – 40 m)' with a trunk diameter up to circa 24 inches (60 cm), measured at breast height. Exceptional specimens can reach 150 feet (46 m) tall, with a 12-inch (30 cm) trunk diameter.
The sitka spruce is unique in that it can absorb minerals from the ocean such as calcium and phosphorus. On average, in british columbia, sitka spruce trees grow 8-12 feet in diameter and 160-180 feet in height.
While red spruce trees can live for 400 years, balsam fir is shorter-lived, and begins to decay after 60+ years and won’t live beyond 200 years. The resulting standing dead trees, or “snags,” are a rich source of insects and provide tree cavities for wildlife such as black-backed and three-toed woodpeckers (see picture at right).

The physiological and ecological characteristics of red spruce ( picea rubens sarg. ) are reviewed and integrated into ecosystem management options. Red spruce is a shade-tolerant, late-successional conifer species found in the temperate forests of northeastern north america. Its wood, being of excellent quality, is prized by the forest industry. Unfortunately, this high-value species has been in decline throughout its entire range for the past 50 years.
Often farmed as a christmas tree and for wood pulp, the red spruce is upright, oval, and extremely long-lived. It can be planted in areas that receive shade (it's especially tolerant of shade when young), should stay relatively cool, and requires adequate moisture.
Some of the silvical characteristics of the sev eral species are given in table 2, appendix (powells 1965). Generally ample moisture is availa ble, and soil temperatures are moderate. Litter and humus are poorer seedbeds because they are likely to be drier and hotter than mineral soil.
Red spruce was successfully establishing and expanding across the ecotone into the hardwood forest zone. The greatest increase of red spruce was seen in the more disturbed and earlier successional sites, whereas the less disturbed red spruce community experienced the least change.
The following features of the spruce needles will distinguish spruce from other conifers: the needles are not flat, they are 3-dimensional and usually pretty stiff, the needles have a point at the end which is painfully sharp on some species like colorado spruce (picea pungens), the spruce needles grow directly from the small new stems, they are not grouped together like pines and true cedars are, the base of each spruce needle has a very small brown connection to the stem, needle colors.
Perhaps it’s most well-known use is its effectiveness as a tonewood, which makes it a perfect choice for making guitars and violins. The tree is, however, susceptible to windthrow and acid rain, both of which can damage it rather easily.
