Overall, the long-term mean annual germination percentage is only around 8% in the forest, and 5% at the treeline, indicating that it takes a white spruce tree quite a bit of energy, and perhaps luck, to successfully reproduce.

The summer feeding group includes the false hemlock looper (Nepytia canosaria Walker), occasionally occurring in large numbers and usually in conjunction with the hemlock looper (Lambdina fiscellaria fiscellaria Guenée), the small spruce loopers Eupithecia species, the yellowlined conifer looper (Cladara limitaria Walker), and the saddleback looper (Ectropis crepuscularia Denis and Schiffermüller). It now has become naturalized southward into the far northern United States border states like Montana, Minnesota, Wisconsin, Michigan, Vermont, New Hampshire and Maine; there is also an isolated population in the Black Hills of South Dakota and Wyoming. The late summer and fall group includes the common spruce-fir looper (Semiothisa signaria dispuncta Walker) and the similar hemlock angle (moth) Macaria fissinotata Walker on hemlock, the small spruce loopers Eupithecia species, the gray spruce looper Caripeta divisata Walker, occasionally abundant, the black-dashed hydriomena moth (Hydriomena divisaria Walker), and the whitelined looper (Eufidonia notataria Walker). [7][115], Outbreaks of spruce beetles have destroyed over 2,300,000 acres (9,300 km2) of forests in Alaska. Nisbet (1905)[55] gave the range of white spruce as extending to “Carolina”, but he did not recognize red spruce as a species and presumably included it with white spruce. Res. p. 57–62. 1986.

White spruce will grow in USDA Growing Zones 3-7, but is not adapted to heat and humidity and will perform poorly in a hot climate. 100 47 99. Res. White spruce can live for several hundred years. However, high cone and seed production does not necessarily mean high seed viability since slightly different climatic factors control success of the two processes. 1966. (1968). 53 p. Viereck, L.A. (1973). [49] Spruce characteristically occurs in fingers of tree-form forest, extending far down the northern rivers and as scattered clumps of dwarfed “bush” spruce on intervening lands (Munns 1938, Halliday and Brown 1943).

Heikinheimo (1915 cited by Lutz 1956),[109][110] found that birch ash inhibited white spruce seedlings, and Gregory (1966)[111] found that birch litter has a smothering effect on spruce seedlings” (Neiland and Viereck 1977).[112]. [84] Minimum soil-fertility standards recommended for white spruce sufficient to produce 126 to 157 m3/ha of wood at 40 years are much higher than for pine species commonly planted in the Lake States (Wilde 1966):[85] 3.5% organic matter, 12.0 meq/100 g exchange capacity, 0.12% total N, 44.8 kg/ha available P, 145.7 kg/ha available K, 3.00 meq/100 g exchangeable Ca, and 0.70 meq/100 g exchangeable Mg. Forest floors under stands dominated by white spruce respond in ways that vary with site conditions, including the disturbance history of the site (Nienstaedt and Zasada 1990).
