Planted Englemann spruce seedlings from 20 sources throughout North America were field tested in the central Rockies at 9,600 feet (2,930 m) elevation. Overall survival was 73% after 10 years. Significant differences in height were evident among several sources. Sources from northern latitudes and lower elevations grew best. The results demonstrate that Englemann spruce planted at high elevations can survive when proper planting techniques and yearly maintenance procedures are used.
