An analysis of a Hackberry–American Elm–green Ash forest type at Moser Park, Allen County, Indiana

Abstract

Abstract Moser Park is a property in Allen County, Indiana, managed by New Haven Parks and Recreation. We conducted a plant survey within the forested section of the park, identifying and quantifying abundance of understory, midstory, and overstory plants. We calculated species richness and Shannon's index for all three strata and tested for relationships with environmental variables (i.e., canopy cover, soil compaction, litter depth, and light availability). The majority of understory species are typically associated with disturbed habitats, with very little resemblance to natural, pre-settlement habitat (i.e., low coefficient of conservation values). Understory cover was dominated by Rubus allegheniensis. Midstory stratum was less diverse than the understory and was dominated by an abundance of Fraxinus pennsylvanica, which was also an important species in the overstory. The forest at Moser Park matched the Hackberry–American Elm–Green Ash forest type. There was a lack of both Quercus and many Acer spec...
