Figure 11. The average diameter at breast height (DBH) of all subalpine fir in the Raft River
plot is displayed, by tree status. Trees are grouped by living (green bar) or dead (grey bar) with
the red bars indicating trees killed by D. confusus (year or age of attack on the x-axis). The
percent of trees in each category is indicated on each bar of the graph.
Table 23. List of eleven one hectare permanent sample plots established to monitor attack dynamics of D.
confusus and other pests of subalpine fir forests. For each plot the following is listed: geographic location;
year of plot establishment and last assessment; plot elevation; biogeoclimatic zone (BEC); attack phase at
stand establishment; stems per hectare of all species and subalpine fir; and, percent subalpine fir killed by D.
confusus.
