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.
