Engelmann Spruce and Blue Spruce are very similar and difficult to distinguish from each other, but knowing several characteristics helps. Elevation: Engelmann Spruce likes drier and higher slopes (9,' to tundra krummholz); Blue Spruce likes streamsides and lower elevations (7,' to 10,'). Cones: Engelmann cones are usually less than two inches long; Blue Spruce are Missing: Genetics. The following is based on the authors' summary of this account of investigations carried out in western Colorado since on the bionomics and control of Dendroctonus engelmanni[Dendroctonus rufipennis] Hopk., a Scolytid that caused severe losses of Engelmann spruce (Picea engelmanni) and to a less extent of lodgepole pine (Pinus contorta) there in Cited by:
Spruce-Pine-Fir (South) This species combination, classed as moderately strong, is cross-continental in origin. Because of similar design values, the combination includes Engelmann and Sitka spruces, and Lodgepole Pine from the West, along with Balsam Fir, Jack Pine, Red Pine and several eastern spruces from the U.S. Northeast. Sample collection. Fresh needle tissue from individuals from 13 populations (nine allopatric and four sympatric) of white spruce, Engelmann spruce and their hybrids were sampled for DNA extraction (Figure 1, Table 1).In order to use previously collected, available genetic resources, needles were collected from grafted individuals cloned from trees in natural populations and Cited by:

Engelmann spruce, Genetics Publisher [Washington]: Forest Service, U.S. Dept. of Agriculture CollectionPages: Genetic diversity and genetic structure in Engelmann spruce (Picea engelmannii Parry ex Engelm.) were interpreted with respect to the effects of glacial and interglacial displacement and compared with patterns in blue spruce (Picea pungens Engelm.), which occupies a range well south of the last glacial front.
On average, Engelmann spruce populations were polymorphic. about genetic structure in Engelmann spruce, a comparison with blue spruce is of interest with respect to the effects of warming climate.
We would expect the subalpine species, Engelmann spruce, to have suffered greater bottlenecks than the montane blue spruce during late Pleistocene and Holo-cene by: Genetic diversity and genetic structure in Engelmann spruce (Picea engelmannii Parry ex Engelm.) were interpreted with respect to the effects of glacial and interglacial displacement and compared with patterns in blue spruce (Picea pungens Engelm.), which occupies a range well south of the last glacial by: Engelmann spruce is one of the seven species of spruce indigenous to the United States (62).
Other common names are Columbian spruce, mountain spruce, white spruce, silver spruce, and pino real. Habitat Native Range. Engelmann spruce is widely distributed in the western United States and two provinces in Canada (61). Engelmann Spruce Engelmann Spruce The Engelmann spruce is the most widespread spruce tree in America, and is one of the important forest trees of the southern Rocky Mountain forest ecosystems.
Engelmann spruce grows in areas of considerable moisture, usually above feet ( m). It is most often found in high forests,Missing: Genetics. Engelmann spruce is found in some of the highest and coldest forest environments in the western United States, characterized by long, cold winters with heavy snowpack and short, cool summers.
It extends down to lower elevations along stream bottoms where cold air flows down the valley and collects in localized frost g: Genetics. The western spruce budworm is another potentially damaging insect that attacks both Engelmann spruce and subalpine fir.
Complete removal of a spruce-fir stand by fire or logging results in such drastic environmental changes that spruce and fir are usually replaced by lodgepole pine, aspen, or shrub and grass communities. TheMissing: Genetics. Engelmann spruce is a medium- to large-sized evergreen conifer indigenous to the western parts of North America, typically growing at high altitudes between 3, ft ft ( m and 3, m).
These spruce trees have a pyramidal crown with a slightly rounded top and their branches extend to the ground, giving the whole [ ]Missing: Genetics. In areas where Engelmann spruce is abundant and lodgepole pine scarce before burning, Engelmann spruce establishes rapidly after fire if sufficient numbers of seed trees survive or are near the burn.
If lodgepole pine is present in the preburn community, it usually seeds in aggressively, assuming a dominant role as it overtops any spruce.
This report summarizes information on distribution, botanical description, habitat conditions, life history, special uses, and genetics of Engelmann spruce. Additional Physical Format: Online version: Fowler, D.P. (Donald Paige), Genetics of Engelmann spruce.
[Washington, D.C.]: Dept. of Agriculture, Forest Service. Color/Appearance: Engelmann Spruce is usually a cream to almost white color, with an occasional hint of red.
Grain/Texture: Engelmann Spruce has a fine, even texture, and a consistently straight grain; numerous small knots are also common. Rot Resistance: Heartwood is rated as being slightly resistant to non-resistant to decay.
Workability: Easy to work, as long as Missing: Genetics. Engelmann spruce is one of the four spruce species indigenous to British Columbia. It is a medium- to large-sized (occasionally >50 m tall), evergreen conifer, with a dense, symmetrical, narrow, spire-like crown; lower branches sloping downward; and a thin, gray-brown bark broken into large, loose, coarse, rounded scales.
Canonical discriminant analyses detected one population of blue spruce that had been misidentified, readily separated populations of blue and Engelmann spruce, suggested that three Southwest populations differed markedly from Intermountain populations of Engelmann spruce, but identified no Intermountain populations that reflected introgression with blue spruce.
