Species Losses, Invasions and Homogenization in Wisconsin Forests Over 50 years
Using a 50 year old baseline data set of 190 upland forest sites across Wisconsin, we examine rates of change in forest plant communities. We tested the hypothesis that Wisconsin forests are losing native diversity, gaining exotic taxa and increasing in similarity. We also tested the hypothesis that the magnitudes of these trends are a function of classic island biogeography theory and/or human influences. Overall, we observed significant reduction in species diversity (avg loss 18%, p-value
