A 70-Year History of Arborescent Vegetation of Inwood Park, Manhattan, New York, U.S.
Richard Stalter and Dwight Kincaid
Abstract: The arborescent vegetation located at three sites within Inwood Park, Manhattan, New York, U.S. was sampled by the quadrat method in October 2004 and May 2005 and compared with the trees present in the same quadrats on a map of trees at Inwood Park prepared by the federal Works Program Administration in 1935. Tulip poplar (Liriodendron tulipifera) was the dominant tree at the Moist Valley and South Slope sites in 1935 and 2005, whereas oak (Quercus) was the dominant genus at Dry Ridge in 1935 and 2005. Dogwood (Cornus florida) was the dominant subcanopy tree in 1935; it was unimportant in 2005, a victim of dogwood anthracnose. In terms of ecologic dominance, there has been no change in the first ranked genera at these sites in the past 70 years. Mean tree diameter (diameter at breast height) has increased from 32.3 cm (12.9 in) to 41.8 cm (16.7 in). The three sites have experienced a parallel pattern of increase in tree size from 1935 to 2005. Nonnative trees were not important in Inwood Park in 2005.
