Fig 7. Conifer composition change from 1993 to 1941 differs among forests.

Conifer composition on the y-axis shows a change in conifer composition percentage, here all values are positive showing increases among all forests e.g., if a stand’s conifer composition was 20% in 1941 and 70% in 1993, it’s conifer composition change was 50% (e.g. 70–20 = 50%). Error bars represent standard error of least squares means, and same letter denotes no significant difference among categories.
