CT: The objective of my research is to develop and refine environmentally sound silvicultural practices that enhance growth, development, quality and value of both individual trees and existing hardwood stands on the major river bottoms and minor streambottoms across the southern United States. Particular emphasis is placed on understanding those factors that influence bole quality, especially the formation of epicormic branches, and how they may be related to tree health. The research approach is executed through a four-pronged framework comprised of (1) applied studies of intermediate stand silviculture designed to evaluate the effects of various types of partial cuttings (improvement cuttings, thinnings, and release cuttings) on growth, quality, and value of commercial tree species in existing hardwood stands; (2) basic studies of bole and log quality designed to describe the process of epicormic branch production in standing hardwood trees and to identify and prioritize those factors that influence this phenomenon; (3) modeling studies to develop decision rules and conceptual models to aid in the selection of the most appropriate thinning prescription to apply in any given hardwood stand; and (4) synthesis efforts to develop practical silvicultural guidelines, management tools, and management systems that optimize growth, quality, and value of existing hardwood stands. Most of the research is conducted in natural, even-aged, mixed-species stands of bottomland hardwoods, but some studies are conducted in oak plantations of various ages and in uneven-aged, mixed-species stands on loessial upland sites.

N: 1. Unshaped large piece of tree, early 14c., of unknown origin. Old Norse had lag “felled tree” (from stem of liggja “to lie”), but on phonological grounds many etymologists deny that this is the root of English log. Instead, they suggest an independent formation meant to “express the notion of something massive by a word of appropriate sound.” OED compares clog (n.) in its original Middle English sense “lump of wood.” Log cabin (1770) in American English has been a figure of the honest pioneer since the 1840 presidential campaign of William Henry Harrison. Falling off a log as a type of something easy to do is from 1839.
2. Any section of the bole, or of the thicker branches, of a felled tree, after trimming and cross-cutting.
3. log: term standardized by CSA International.
