Invasive species pose a threat to aquatic and terrestrial ecosystems by decreasing biodiversity (Didham et al. 2005). The mechanism by which invasive species negatively impact environments is typically through either the direct effect of increased dominance or the indirect effect of territory modification. Invasive plant species have the potential to affect both other flora and fauna when grown out of cultivation. Amur bush honeysuckle (Lonicera maackii) was brought to the United States from northeast Asia in 1898 as an ornamental plant intended for land restoration and to provide habitat for birds (Luken and Thieret 1996). The woody shrub has since escaped cultivation and is currently considered invasive in 27 states according to the USDA. Its early leaf phenology, production of copious red berries, allelopathic effects, and morphological plasticity provide Amur honeysuckle with a competitive advantage over native plants (Ingold and Craycraft 1983;Luken and Thieret 1996; McEwan et al. 2010). tree diversity, percent canopy cover, and mean tree height of forest stands will negatively correlate with honeysuckle density because of the life history traits of honeysuckle; 3b) the extent of anthropogenic influence will positively correlate with honeysuckle density because of the potential affinity of honeysuckle for more disturbed, urbanized habitats.In order to test the hypotheses, thirteen forest stands within the Louisville Metropolitan Area were selected. They had similar tree composition but varied in density of honeysuckle [six forest stands with Lonicera maackii present and seven stands with little to no honeysuckle]. Vegetation surveys and an assessment of anthropogenic impact were conducted at all stands. Bird surveys were performed at each stand once every vi season for two years by walking a one-kilometer trail and identifying birds visually and acoustically within 20 meters of either side of the trail. Multiple regression analyses using PROC MIXED of SAS examined the effects of honeysuckle density, tree diversity, mean tree height, percent canopy cover, and extent of anthropogenic influence on bird diversity (Goodnight 2015). Honeysuckle density (p = 0.0208) and anthropogenic influence (p = 0.0439) significantly negatively impacted bird diversity but these effects did not significantly vary seasonally. Urbanized forest stands cannot support a wide variety of bird species but rather only species adapted to urban conditions. As predicted, bird diversity had a positive correlation with percent canopy cover and mean tree height.However, these effects were not significant.Nonmetric multidimensional scaling (NMDS) ordination was used to quantify compositional aspects of forest stands into axis values to visualize the effects of honeysuckle density on bird species and families. Effects of the representative values of compositional components (axes) and honeysuckle density on abundance of the most abundant birds observed during the study and on bird families were analyzed using generalized Poisson regression for e...
