Abstract:

The aim of the study was evaluation of knots in wood of 150-year-old Norway spruce [Picea abies (L.) Karst.] in stands situated at the altitude of 1450– 1740 m above sea level in the Dolomites in Italian section of the Alps. In selected stands, spruce trees were cut down and their length, stem thickness, height to the crown base and stem diameters at every 1 m along the length of merchantable bole were measured. The diameter of knots was measured and they were classified according to their healthiness and the degree of their tightness with the surrounding wood. The relative knot diameter

Abstract:

Abstract No volume tables are available for cypress in the South. A volume and stem-profile prediction system for baldcypress (Taxodium distichum) is presented in this paper. Equations for estimating total and merchantable inside- and outside-bark cubic foot volumes are discussed, as well as a stem-profile equation for estimating diameter at any point on the tree bole. These equations are based on diameters measured at 10 feet above the ground. The prediction system was developed from 157 sample trees measured on 26 locations scattered throughout the south Delta region of Louisiana. Normal dia

Abstract:

A sampling methodology to provide an unbiased estimate of bole volume is introduced, with specific regard to its incorporation as an alternative to detailed dendrometry in a 3P sampling framework. In a demonstration of the technique to estimate merchantable volume in a 91-tree population, the average relative sampling error was 7.4%. A two-tool implementation of 3P sampling is proposed and discussed.

Abstract:

The study was conducted on 9 sample of Norway spruce [Picea abies (L.) Karst] trees, aged 150 years, from three upper subalpine stands in the region of the Dolomites. The knots were classified into three categories of healthiness and three categories of intergrowth with the surrounding wood. Differences in diameters and relative diameters of knots classified into three categories of healthiness and three categories of intergrowth with the surrounding wood was shown on a merchantable bole divided into 10 equal sections. The frequency of occurrence of knots under the analysed categories was the

Abstract:

Abstract Stem analysis data collected from 101 sample trees located in 12 plantations established between 1930 and 1982 throughout central Maine were used to develop total and merchantable stem volume prediction equations, and site index prediction equations for plantation-grown European larch. The inside bark merchantable volume equation (4 in. top dob and 12 ft minimum merchantable bole) using a weighted combined variable was very similar to one for Japanese larch in Pennsylvania. Site index curves from this study were identical to those developed in southern New York and New England below a

Abstract:

Abstract Equations are needed to estimate the green weight of loblolly pine (Pinus taeda L.) trees across the commercial range in the South. Thus, a study was conducted to derive models for predicting green weight of total and merchantable bole portions. Equations were fitted to sectional tree stem observations where a serial correlation was discerned among the data, indicating an intratree relationship. Linear equations utilizing a correction for serial correlation did not outperform an uncorrected nonlinear equation form. Three data sets were combined, and regionwide prediction models for to

To establish the allometric equation 350 sample trees were measured to determine the relationships between tree height (H) and diameter breast height (D). Thirty trees of various sizes were cut to measure the merchantable timber and firewood volume. The raw merchantable timber volume of teak in the community forest w

Abstract:

Abstract Vertical and horizontal modes of both importance and control-variate sampling for estimating merchantable and total volumes of boles are described and compared. In the horizontal mode, heights are selected at random, and cross-sectional areas are measured. In the vertical mode, cross-sectional areas are selected at random and heights are measured. Estimates obtained by horizontal and vertical control-variate sampling (also known as the critical height method) were equally precise in tests using a proxy taper equation that was linear in cross-sectional area versus height. Both methods

Abstract:

An unbiased profile model, fit to diameter divided by diameter at breast height, overestimated volume of 5.3-m log sections by 0.5 to 3.5%. Another unbiased profile model, fit to squared diameter divided by squared diameter at breast height, underestimated bole diameters by 0.2 to 2.1%. These biases are caused by retransformation of the predicted dependent variable; the degree of retransformation bias depends upon choice of dependent variable in the regression model, variance of its prediction errors, and the bole position of the desired prediction. Retransformation biases were greatest near t

Abstract:

Accurate estimates of tree bole volume are fundamental to sustainable forest management. Total inside and outside bark and merchantable volume equations were developed for 25 major commercial tree species grown in natural stands in eastern and central Canada and the northeastern United States. Data used to develop these equations was collected from 9647 trees sampled from natural stands across the study area. The number of trees sampled varied among species. Jack pine (Pinus banksiana Lamb.) had the most observations (1648 trees) and American basswood (Tilia americana) and red oak (Quercus rub
