";s:4:"text";s:6067:"It is closely related to black spruce, and hybrids between the two are frequent where their ranges meet. More broadly, it can be found from the Maritime Provinces of Canada west to southern Ontario and south to the highlands of northern New Jersey and northeastern Pennsylvania. Red spruce are particularly sensitive to acid rain and, at the height of the die-off, some forests lost 50 per cent of them. The forest, consisting of 50,000 trees was dedicated in 1940 and had until recently been forgotten until Tartt located and identified the forest. Red Spruce and spruce-fir forest types are used by many iconic wildlife species of the north woods, including American Marten, Snowshoe Hare, and Canada Lynx. [12] It is often found in pure stands or forests mixed with eastern white pine, balsam fir, or black spruce. This species is a member of the pine family. [3][4][5] This species is also known as yellow spruce, West Virginia spruce, eastern spruce, and he-balsam. [6][7], Red spruce is a perennial,[8] shade-tolerant, late successional[9] coniferous tree that under optimal conditions grows to 18–40 m (59–131 ft) tall with a trunk diameter of about 60 cm (24 in), though exceptional specimens can reach 46 m (151 ft) tall and 100 cm (39 inches) in diameter. Notable red spruce forests can be seen at Gaudineer Scenic Area, a virgin red spruce forest located in West Virginia, the Canaan Valley, Roaring Plains West Wilderness, Dolly Sods Wilderness, Spruce Mountain and Spruce Knob all also in West Virginia and all sites of former extensive red spruce forest. The wood is light, soft, has narrow rings, and has a slight red tinge. [19], One of the consequences of acid rain deposition is the decrease of soil exchangeable calcium and increase of aluminum. This tree was found and measured by participants in the 2003 Youth Conservation Camp sponsored by … The Red Spruce (Picea rubens) is a medium-sized evergreen conifer that grows in cool, boreal forests of the northeast, including the Adirondack Mountains.Red spruce is the provincial tree of Nova Scotia. In the 1970s, red spruce was the forest equivalent of a canary in the coal mine, signaling that acid rain was damaging forests and that some species – especially red spruce – were particularly sensitive to this human induced damage. Guild: persistent, slow-growing, long-lived, tolerant. The bark of mature trees can be described as grayish-brown flakes covering a reddish-brown layer beneath. One study testing the effects of added aluminum to soil, found that P. rubens mortality rate increased under these conditions. Dense, mature spruce-fir stands also provide critical winter habitat for White-tailed Deer in the northern extent of its range. [10] The cones are cylindrical, 3–5 cm (1 1⁄4–2 in) long, with a glossy red-brown color and stiff scales. Sap that flowed from wounds in the trunk was collected after it had hardened. Picea rubens, commonly known as red spruce, is a species of spruce native to eastern North America, ranging from eastern Quebec and Nova Scotia, west to the Adirondack Mountains and south through New England along the Appalachians to western North Carolina. Red Spruce is managed throughout its range using a variety of techniques, from single-tree selection to clearcutting. [26], Significant efforts have been made to increase the growth of red spruce trees in western North Carolina. Red Spruce provided the critical raw material to a booming spruce gum industry in Maine during the latter part of the 19th century. Red Spruce is a long-loved species and can grow to more than 350 years in age. They grow individually all around the twig as opposed to pines, whose needles grow in groups of two to five. At the ecosystem and community levels, Calcium availability is associated with community composition, mature tree growth, and ecosystem productivity. [17], Red spruce is the provincial tree of Nova Scotia. The shiny, yellow-green needles are four-sided with pointy tips as opposed to the flat, rounded needles of fir (spiny spruce, friendly fir). It is the largest known tree of its species in the country as reported to American Forests. This is because acid precipitation disrupts cation and nutrition cycling in forest ecosystems. Therefore, the forest types that dominate are spruce-fir (red spruce is more prevalent here than the more northerly white spruce) and northern hardwoods (maple, birch, and beech). Red Spruce is a coniferous tree that retains its needles year-round. Despite its name, the Spruce Budworm prefers to feed on Balsam Fir. Red spruce, Picea rubens, is a common forest tree of the Acadian forest region. Barton M. Blum.
