To identify and prioritize natural areas for consideration as research natural areas (RNAs) on the Superior National Forest (National Forest hereafter NF) in northeastern Minnesota, we developed a six-step approach that could be applied to natural ar

We studied the dynamics of coarse woody debris (logs and snags) in old-growth forests by estimating rates of tree mortality, snag change, and log decay in hemlock–hardwood stands located in northern Wisconsin and northern Michigan. To estimate mort

We characterized the structure of 25 old-growth hemlock-hardwood forests in northern Wisconsin and adjacent Michigan in order to examine our working hypotheses that differences in their structure are related to stand age (i.e., stage of development)

Throughout interior Alaska (U.S.A.), a gradual warming trend in mean monthly temperatures occurred over the last few decades (approximatlely 2-4 degrees C). The accompanying increases in woody vegetation at many alpine treeline (hereafter treeline) l

Compiles information about old-growth attributes for nine forest type groups that occur in the eastern United States. A range of values for each old-growth attribute for each forest type is summarized regionally from published and unpublished sources

This study compared how two tree species with different leaf life-spans differ in their adaptations to low nutrient availability in a Wisconsin bog. Seasonal patterns of foliar nutrient concentration, nutrient resorption, leaching loss to simulated r

Species of Trillium in the subgenus Phyllantherum are either polymorphic for flower color, or monomorphic for flower color and related to a polymorphic species. This leads to the suggestion that polymorphic species may be the progenitors for monomorp
