Title: Rotated sigmoid structures in managed uneven-aged northern hardwood stands: a look at the Burr Type III distribution

Author: Gove, Jeffrey H.; Ducey, Mark J.; Leak, William B.; Zhang, Lianjun;

Date: 2008

Source: Forestry. 161-176.

Publication Series: Scientific Journal (JRNL)

Description: Stand structures from a combined density manipulation and even- to uneven-aged conversion experiment on the Bartlett Experimental Forest (New Hampshire, USA) were examined 25 years after initial treatment for rotated sigmoidal diameter distributions. A comparison was made on these stands between two probability density functions for fitting these residual structures: the Burr Type III and a finite mixture of Weibulls. All stands exhibited some form of uneven-aged structure (either reverse J or rotated sigmoid) after 25 years. The Burr distribution fits the final distributions as well as the more complicated finite mixture model in all cases.
