Interpretation Guide
Red spruce is narrow ranged (3.3% of area), but high density and importance where it exists. Red spruce models show little change in area but substantial decrease in mean IV, so that habitat suitability is expected to decline. Its adaptability is also rather low. It is rebounding in growth in some areas now due to reductions in acidic deposition, has a fairly reliable model, and is common in the NE; yet, we suggest a poor rating of capability to cope mostly because of its low adaptability including regeneration difficulties. SHIFT shows some infill.
Family: Pinaceae
