Interpretation Guide
White spruce is a narrow ranged (4.5% of area), sparse species of low importance where it occurs. Our models show some increase in suitable habitat area, but a reduction of mean IV so that there is a loss in suitable habitat (though still classed as 'No change'). A substantial increase in annual temperature is likely to stress the species already in decline over part of its range. We suggest it has a fair capability to cope with climate change. SHIFT shows a lot of infill.
Family: Pinaceae
Guild: opportunistic, long-lived, intermediate shade tolerance
