Impact and pattern of an invasion by Phellodendron amurenseRupr. in an urban and suburban woodland.

Phellodendron amurense Rupr., an introduced ornamental species in the northeastern United States has shown invasive potential throughout the region. To analyze the impact of the species, understory plots were placed at locations where P. amurense populations have reached more than 100 mature individuals. Location 1 was at the Bartlett Arboretum in Fairfield County, CT and Location 2 within Forest Park, Queens County, NY. Additional plots were then placed in the surrounding woodlands at each site where no P. amurense individuals were present. These plots were analyzed to measure a number of parameters including species richness, diversity, and an analysis of native versus non native understory components. Analysis of Variance showed a significant difference in both total understory individuals and total native species at both sites with P. amurense invaded plots showing lower values in both categories (P > .0001). Using tree ring analysis, diameter breast height, and cartesian coordinate data, the pattern of invasion at the Fairfield County site was then re-created to help better understand the method of invasion by this species by applying this data to statistical methods and through the use of animated bubble charts.
