Mortality rates generally decrease sharply thereafter, but losses often remain high for some years. The nuclear,[50] mitochondrial[51][52] and chloroplast[53] genomes of British Columbia interior spruce have been sequenced. 111. Res. [40] Repeated applications of half a million seeds/ha failed to produce the 750 trees/ha sought by Northwest Pulp and Power, Ltd., near Hinton, Alberta (Radvanyi 1972),[41] but no doubt left a lot of well-fed small mammals.

Dead needles show rows of black fruiting bodies. (1994),[11] that cone scale morphology was the feature most useful in differentiating species of spruce; the length, width, length: width ratio, the length of free scale (the distance from the imprint of the seed wing to the tip of the scale), and the percentage free scale (length of free scale as a percentage of the total length of the scale) were most useful in this regard.
