Distribution of forest basal area (BA; m2 ha−1) showing the relative abundance of conifer and broadleaf forest associates among 61 random field plots sampled in 2015 and 2016 within the Superior National Forest, Minnesota, USA. Shown are three forest BA levels (0 to 5, 5 to 10, and ≥10 m2 ha−1) for eight conifer species and two generalized forest groups: conifer (CON) and broadleaf (BRD). Sampled conifer species include balsam fir (ABBA), white spruce (PIGL), black spruce (PIMA), tamarack (LALA), jack pine (PIBA), red pine (PIRE), eastern white pine (PIST), and northern white cedar (THOC)
