Appendix A. Table with detailed information forest stands studied in western Montana, USA.
Table A1. Forest stands studied in western Montana, USA. Variables include stand area (ha), site (MTH = Mt. Haggin Wildlife Management Area, and L&C = Lewis & Clark National Forest), sample size of systematic vegetation plots (n), mean basal area density (m²/ha) of four variables used in PCA (conifer stems, conifer trees, deciduous stems, and deciduous trees), percent conifer composition, as well as mean (± SE) of PCconifer (PCcon) and PCdeciduous (PCdec) from each forest stand for observational analyses. Stands are arranged by increasing conifer composition (PCconifer).

† Conifers were removed from stands in Fall 2010; only data from years prior to removal were used in observational analyses.
‡ Control stands for conifer removal experiment; data from these stands were used in observational analyses.
