The frequency and percent surface area covered by necrotic flecking on red spruce (Picearubens Sarg.) needles from sapling-sized trees were examined on nine research sites on three mountains in the southern Appalachians. Foliar pigment analysis was conducted on trees from two of the nine research sites. Flecking increased with foliar age on all sites, and on two of the mountains the area covered by flecks increased with elevation. Above 1720 m on Clingman's Dome, foliar flecking was found to… CONTINUE READING
