White Spruce (Sw) - Picea Glauca
White spruce (Sw) - Picea glauca Tree Species > White spruce Page Index Distribution Range and Amplitiudes Tolerances and Damaging Agents Silvical Characteristics Genetics and Notes BC Distribution of White spruce (Sw) Range of White spruce An open canopy stand of white spruce and trembling aspen on Morice River alluvial terrace. Pure white spruce stands are infrequent in th fire-disturbed, montane boreal landscape. Geographic Range and Ecological Amplitudes Description White spruce is a medium-sized (occasionally >55 m tall), evergreen conifer, with a fairly symmetrical, conical crown, a regular branching pattern that often extends to the ground, and a smooth, dark gray, scaly bark. The wood of white spruce is light, straight grained, and resilient. It is used primarily for lumber and pulp. Geographic Range Geographic element: North American transcontinental-incomplete Distribution in Western North America: (north) in the Pacific region; north and central in the Cordilleran region Ecological Climatic amplitude: Amplitudes subarctic – subalpine boreal – montane boreal – (cool temperate) Orographic amplitude: montane – subalpine Occurrence in biogeoclimatic zones: SWB, (ESSF), MS, BWBS, SBS, SBPS, (IDF), (ICH), (northern CWH) Edaphic Amplitude Range of soil moisture regimes: (very dry) – moderately dry – slightly dry – fresh – moist – very moist – wet Range of soil nutrient regimes: (very poor) – poor – medium – rich – very rich In the BWBS zone, white spruce grows well on medium and rich sites providing a Moder humus formation exists. Wildfires are the major disturbance factor in re-establishing a white spruce stand when acidic Mors begin to develop, a humus form which favors the regeneration and growth of black spruce. Without the fires, the more shade-tolerant black spruce would become a dominant species and form a climatic climax stand. -

Rea Rea, R.V. 2011. Impacts of Moose (Alces alces) browsing on paper birch (Betula papyrifera) morphology and potential timber quality. Silva Fennica 45(2): 227–236. Although moose browsing effects on the growth and morphology of birch are well studied, effects of moose browsing on potential timber quality of birch have received little attention. Here, an assessment was made of the impacts of moose (Alces alces L.) damage to Paper Birch (Betula papyrifera Marsh.) trees from a 20-year old clear cut area in a sub-boreal spruce forest within the Aleza Lake Research Forest, near Prince George, British Columbia, Canada. Specifically, differences in overall tree architecture and in the internal characteristics of trees that had been severely damaged and suppressed by moose winter browsing were compared to birch trees that had not been damaged by moose in this way and were considered free-to- grow. The average stem diameter, number of annular growth rings, and height of stem breaks made by moose on suppressed birches at the point of breakage was 17.9 ± 6.6 mm, 4.6 ± 1.2, and 141.8 ± 32.0 cm, respectively. Stem diameters and the heights above-the-ground of stem breaks made by moose during sequential breakage events were not significantly different (all p ≥ 0.05) from one another. -
Picea Glauca Common Name: White Spruce Family Name: Pinaceae
Plant Profiles: HORT 2242 Landscape Plants II Botanical Name: Picea glauca Common Name: white spruce Family Name: Pinaceae – pine family General Description: Picea glauca is a large evergreen conifer widely distributed across the northern parts of North America. It is not, however, native to the Chicago area. The straight species is not considered highly ornamental compared to other spruces but with its ability to withstand cold, heat, wind and drought it is a very serviceable tree especially when used as a wind break. There are a few varieties and cultivars available in the trade. The most commonly used cultivar is Picea glauca ‘Conica’ (sometimes listed as P. glauca var. conica).

The entire region was glaciated during the last part of the Wisconsin Glaciation. It can be characterized by four distinct ecological landscapes: the Superior Coastal (Clay Plain) bordering Lake Superior and extending to a maximum of 15 miles inland, the Northwest Sands extending across the region in a belt of outwash sands and gravel from southwest to northeast, the North Central Forest, and Northwest Lowlands. Region 2: Bayfield and Douglas Counties Section 3: Region 2 • 2-1 (Photo from Kemp Natural Resources Station Archives) This region, with its variety of landscapes, has a mix of forested wetlands as a reflection of it variety in soils and landscape. Boreal swamp conifer (balsam, cedar, black spruce) exist on the clay, nutrient poor peatland of black spruce and tamarack on the sandy outwash and some black ash swamps on deep organic muck soils.

Tamarack an American Wood United States Department of Agriculture
Forest Service Tamarack An American Wood United States Department of Agriculture FS-268 Tamarack grows from Maine to Min- nesota, throughout much of Canada, and in Alaska. Most of its volume in the United States is in the northern Lake States and Maine. The tree, whose needles fall in autumn, is found especially on wet lowlands where it grows fast in full sunlight. The brownish heartwood contrasts with the narrow, whitish sapwood. The wood- one of the heaviest of the northern conifers–is medium to fine textured, odorless, tasteless, and somewhat oily. It rates intermediate in strength, is easi- ly pulped, and has fairly high heating value. Recent use has been largely for pulp products, but in earlier days tamarack was used in the construction of wooden ships and for lumber. An American Wood Tamarack (Larix laricina (Du Roi) K. Koch) William F. Johnston1 and Eugene M. Carpenter2 Distribution Tamarack has one of the widest ranges of all North American conifers (fig. 1). The tree grows throughout much of Canada, with a range extending to the northern limit of tree growth. In the United States tamarack's main range extends from Maine to Minnesota; the tree also grows locally as far south as northern West Virginia. A major dis- junct area occurs in the Yukon and Kuskokwim drainages in interior Alaska. In the United States tamarack is most abundant in the northern Lake States, particularly Minnesota, where it grows mainly on glacial lakebeds and lake- swamp-moraine plains at elevations averaging about 1,000 feet. The tree is also abundant in Maine from elevations of less than 500 feet to more than 1,000 feet. -

How the Capitol Christmas Tree Was Named by John Morton
Refuge Notebook • Vol. 17, No. 52 • December 25, 2015 How the Capitol Christmas Tree was named by John Morton representing 8 species, and 30 spruce representing 8 species. This year’s Capitol Christmas Tree is the first from Alaska and the first Lutz spruce. Lutz spruce is the natural hybrid between Sitka (Picea sitchensis) and white spruce (Picea glauca). Sitka spruce grows in our coastal rainforest from the east- ern Kenai Peninsula to northern California, preferring a maritime climate with moderate temperatures and lots of rain. White spruce grows from the western Kenai Peninsula across Interior Alaska to Newfound- land, preferring a continental climate with extreme temperatures and low precipitation. Here on the Kenai Peninsula, the rainshadow cre- ated by the Kenai Mountains creates unique climate variations where cooler temperatures intersect with moderate rainfall. You can find this microclimate along the Resurrection Trail, sections of the Seward Highway and in Caribou Hills. In the summers of 1950 and 1951, Harold John Lutz collected specimens from Jerome and Kenai Lakes near Cooper Landing that he recognized as a hybrid between the two spruce species. These specimens were subsequently confirmed asa hybrid by Elbert Little of the U.S. Forest Service in 1953, who formally named it “Picea × lutzii” in honor of Lutz. This year’s Capitol Christmas Tree in Washington D.C. Who was Lutz? He didn’t just stumble across this is a Lutz spruce from Primrose on the Kenai Peninsula conifer and take a lucky guess as to its taxonomy. Dr. (photo credit: Architect of the Capitol). Lutz was a professor in the Yale School of Forestry from 1933 to 1968.
