In this paper we present the dollar values and value increases, as well as the rates of value increase, for three of the most important tree species of the Allegheny Plateau of New York and Pennsylvania: black cherry (Prunus serotina Ehrh.), red maple (Acer rubrum L.), and white ash (Fraxinus americana L.).
One-year-old seedlings of yellow-poplar (Liriodendron tulipifera L.), eastern cottonwood (Populus deltoides Bartr.), and white ash (Fraxinus americana L.) were divided into four groups. One group served as the control, and the other groups were fumigated for 12 hours per day with either 0.1 ppm O3
The survival, growth, and stem form of 45 white ash (Fraxinus americana L.) families nested within 22 provenances were evaluated 15 years after establishment in north central West Virginia. Geographic family origins encompassed a wide area in the eastern and central United States, including locations from Maine in the North to Mississippi in the South to Nebraska in...
