Effect of thinning on mixed-oak stem quality by David L Sonderman( )

6 editions published in 1988 in English and held by 412 WorldCat member libraries worldwide

S2Changes in limb-related stem defects were studied from 1977 to 1982 on 595 mixed-oak trees following a schedule of thinnings dating back to 1962. All of the thinnings were controlled by stocking goals rather than predetermined time intervals. Results show that heavy and moderate thinnings, as opposed to light thinning had an adverse effect on the number and size of live and dead limbs. The light thinnings resulted in fewer live and dead limb defects per square foot of surface area but much slower diameter growth. S3
Photographic guide to selected external defect indicators and associated internal defects in black walnut by Everette D Rast( )

4 editions published in 1988 in English and held by 410 WorldCat member libraries worldwide

S2To properly classify or grade logs or trees, one must be able to correctly identify defect indicators and assess the effect of the underlying defect on possible end products. This guide aids the individual in identifying the surface defect indicator and also shows the progressive stages of the defect throughout its development for black walnut. It illustrates and describes 10 types of external defect indicators and associated defects that are particularly difficult to evaluate.S3
Stand density : a factor affecting stem quality of young hardwoods by David L Sonderman( )

5 editions published in 1985 in English and held by 382 WorldCat member libraries worldwide

S2A 14-year-old mixed oak stand was thinned in 1977 to stocking levels of 30, 50, and 60 percent and a control. From this stand, 117 trees were selected and their stem-related defects recorded. Six years later these same trees were reevaluated. The number of limb defects per square foot of surface area increased substantially more in the heavily thinned plots than in the unthinned plots. Trends in these data confirm commonly held beliefs that stand density affects stem quality after only a few years.S3
Quality response of even-aged 80-year-old white oak trees after thinning by David L Sonderman( )

Changes in hardwood growing-stock tree grades by David L Sonderman( )

5 editions published between 1987 and 1988 in English and held by 380 WorldCat member libraries worldwide

S2Describes changes in provisional tree grades for 351 young, mixed upland hardwood trees 6 years after thinning. Treatments of 30, 50, and 70 percent stocking plus a crop-tree release were applied. Results indicate that light thinning and crop-tree thinning produced higher quality and better grade trees than heavy thinning.S3
Changes in stem quality on young thinned hardwoods by David L Sonderman( )

6 editions published in 1986 in English and held by 376 WorldCat member libraries worldwide

S2Describes changes in limb-related defects on 18-year-old, even-aged hardwoods 6 years after thinning. Stocking levels of 30, 45, and 60 percent were studied. There were fewer defects per square foot of surface area in the higher stocking plots than in the lower stocking plots. The average number of live limbs decreased by 83 percent in the unthinned plots and increased slightly in the heavily thinned plots. The results show that the frequency and size of limb-related defects are affected by stand density over a short period of time.S3
Quality response of 29-year-old, even-aged central hardwoods after thinning by David L Sonderman( )

Effect of thinning on growth and potential quality of young white oak crop trees by Martin E Dale( )

Photographic guide of selected external defect indicators and associated internal defects in sugar maple by Everette D Rast( )

4 editions published in 1991 in English and held by 330 WorldCat member libraries worldwide

S2To properly classify or grade logs or trees, one must be able to correctly identify indicators and assess the effect of the underlying defect on possible end products. This guide assists the individual in identifying the surface defect indicator and shows the progressive stages of the defect throughout its development for sugar maple. Eleven types of external defect indicators and associated defects that are particularly difficult to evaluate are illustrated and described.S3

Stem-quality changes on young, mixed upland hardwoods after crop-tree release by David L Sonderman( )

3 editions published in 1987 in English and held by 296 WorldCat member libraries worldwide

"Relative change of several types of stem defects was studied over an 8-year period to determine the effects of crop-tree thinning on the development of tree quality. Special interest was given to changes in relative quality associated with defect indicators of crop trees compared to trees in unthinned plots. The relative quality classes of the crop trees went from "poor" to "medium" for red maple and "poor" to "good" for aspen. The oaks stayed in the poor classification and yellow-poplar remained unchanged in the medium classification. Results showed a decrease in the number of epicormic branches on the crop trees, and an increase in the size of live limbs.S3
