Book Description
The goal of this study was to inventory the nonnative plant populations in each of the four NPS units between 2004 and 2006 at each of the NPS vegetation mapping plots and accuracy assessment points. This report details the results of the inventory for JOFL, which took place in 2004, and ALPO, which took place in 2005–2006. This inventory will contribute to a general understanding of the nonnative plant distributions, identify what species are most prevalent, and determine which vegetation associations are most impacted by nonnative plant species. This report draws attention to survey points and vegetative communities with particularly dense populations of nonnative plants and identifies them as targets for further study and management.

Book Description
Vegetation classification and mapping was conducted at Johnstown Flood National Memorial, creating a current digital geospatial vegetation database for the park. Seven vegetation associations, Red Maple – Black Cherry Successional Forest / Woodland, Eastern Hemlock – Northern Hardwood Forest, Conifer Plantation, Silky Willow Shrub Swamp, Old Field, Cattail Marsh, and Riverine Scour Vegetation, that occur within the park were identified and described in detail.

Book Description
Invasion by non-indigenous plants is widely considered to be a primary threat to species diversity and ecosystem function. Ecosystem changes resulting from these invasions may negatively impact native plant communities as a whole, as well as rare and endangered species. This report explores existing reports on rare plant locations in Mississippi National River and Recreation Area (MISS), and Saint Croix National Scenic Riverway (SACN). No rare plant surveys were performed for this study. In addition, we performed invasive plant surveys on several species considered “target” species of concern at each park. Common buckthorn (Rhamnus cathartica L.) was the most commonly found invasive species. Of the 68 plots sampled in MISS, 53 had at least one invasive species present, and of the 136 plots sampled in SACN, 128 had at least one invasive species present. While this was not an exhaustive attempt to survey all invasive infestations, this study can serve as a template for future surveys and to emphasize the importance of continuity to allow compilation and comparison of data across parks.
