Live crown ratio and stand density in young, even-aged, red oak stands

Live crown ratio and stand density in young, even-aged, red oak stands

Forest Sci 10(1): 56-65

Using a measure of density designated the Crown Competition Index, it was possible to explain 40 to 50% of the variation in the live crown ratio of individual dominant and codominant Quercus rubra trees, in even-aged stands 10 to 40 years old. Crown competition index was the sum of the ratios of a numerical expression of the crown class of each competing tree to its horizontal distance from the individual sample tree. An estimate of the average live crown ratio produced with increased stand age in response to different levels of density was determined from a multiple regression relating live crown ratio to crown competition index and sample tree height.
