Zimmerman E. 2007. Distribution and Abundance of Nonnative Plant Species at Johnstown Flood National Memorial and Allegheny Portage Railroad National Historic Site. Technical Report NPS/NER/NRTR—2007/083. United States Department of Interior, National Park Service, Northeast Region. Philadelphia, Pennsylvania

Nonnative plant species were inventoried at Johnstown Flood National Memorial (JOFL) and Allegheny Portage Railroad National Historic Site (ALPO) during vegetation mapping and classification activities. Fifty-four nonnative species were found among the 50 survey points at JOFL and a total of 92 nonnative species were found amoung the 200 survey points at ALPO. Overall, this study contributes to the general understanding of the nonnative plant distributions, identifies what species are most prevalent, and determines which vegetation associations are most impacted by nonnative plant species.
