Abstract
A 16.1-ha watershed was experimentally clear-cut in 1939 and again in 1962. All material over 1 cm in diameter was cut and left in place, thereby minimizing soil disturbance. Density data collected on permanent quadrats before cutting, 13 yr after the 1st cut and 15 yr following the 2nd cut, indicate vegetation response varies by species and physiographic position. There was also a difference in response between the 2 clear-cuts. There was little change in number of tree species found per unit area following the 2 clear-cuts. Certain species, such as Liriodendron tulipifera, became much more abundant while others decreased in abundance, especially on lower slope to cove and mid to upper N and E physiographic positions following the 2nd cut.
