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
The Allegheny River of western Pennsylvania and New York rises in Potter County, Pennsylvania, and flows 320 miles to its confluence with the Monongahela River in Pittsburgh. The Allegheny's southern watershed district begins in East Brady, Pennsylvania, and ends in Pittsburgh, and it includes the historic Redbank Creek, Mahoning Creek, Crooked Creek, and Kiskiminetas River valleys. Along the Allegheny River: The Southern Watershed features over 200 vintage postcards of the landscapes, people, industries, and events that shaped the history of the southern Allegheny River Valley and of the nation. These absorbing images chronicle over 200 years of history from the frontier wars of the 18th century to the rise and growth of the Industrial Revolution in the late 19th and early 20th centuries.
