    The influence of urban and agricultural landscape contexts on forest diversity and structure across ecoregions by John Paul Schmit, Lea R. Johnson, Matthew Baker, Lindsay Darling, Robert Fahey, Dexter H. Locke, Anita T. Morzillo, Nancy F. Sonti, Tara L. E. Trammell, Myla F. J. Aronson, Michelle L. Johnson

    Published 2025-02-01
    “…Most studies of forest health in urban landscapes have focused on few forest patches across a single metropolitan region, and synthesis is needed to understand broader patterns. We assessed variation among measures of forest health across land cover gradients and ecoregions by determining (1) whether the degree of urban, agricultural, and forested land surrounding a forest patch was reflected in differences in tree community composition, diversity, and structure and (2) whether these differences were consistent across ecoregions. …”
