 Interpretation Guide


Black spruce occupies the northern tier and has narrow range (3.4% of area), sparse density, but relatively high importance where it occurs (FIAiv=10.3, similar to balsam fir). Though black spruce models do not change greatly in area occupied, the large reduction of mean IV yielded a decrease in suitable habitat. Its medium adaptability was influenced by both positive (e.g., dispersal) and negative traits (insects, fire, drought); we score it with a poor capability to cope because of the negative factors and decrease in suitable habitat. Nonetheless, the SHIFT model suggests it a decent species for infilling.
