Novel approaches were developed to assess the occurrence and potential impacts of spatial autocorrelation on correlation analyses involving invasive/native species and related community constructs. Results suggest new significance levels are warranted for correlation analyses. The sequential reduction of autocorrelation in the data revealed habitat- v. ecosystem-level effects and non-effects relative to bioinvasion. Taken together, these outcomes provide a novel framework for prioritizing land management and restoration-related decisions.
