Cubic-foot volume, surface area, and merchantable height functions for longleaf pine trees / Robert M. Farrar, : Robert M. Farrar.

We developed a set of individual tree equations to predict tree height (H, m), stem diameter inside bark at m height (dbhIB, cm), stem volume outside bark (VOB, m3), and stem volume inside.

We developed a set of individual tree equations to predict tree height (H, m), stem diameter inside bark at m height (dbh IB, cm), stem volume outside bark (V OB, m 3), and stem volume inside bark (V IB, m 3), as well as functions to determine merchantable stem volume ratio (both outside and inside bark) from the stump to any top by: Cubic-Foot Volume of Loblolly Pine to Any Merchantable Top Limit.

Foresters commonly wish to predict tree volume for various top diameters. However, tree volume equations are generally restricted to specific top limits. Further, volume equations Author: Harold E. Burkhart. Stem profile data from loblolly pine (Pinus taeda L.) trees grown in cutover, site-prepared plantations across much of the South were used to develop total and merchantable cubic-foot volume.

Board-Foot, Cubic-Foot, and Cubic-Meter Volume Tables for Commercial Forest Species of Pennsylvania provides conversion tables for calculating merchantable lumber volumes of all commercially important species in Pennsylvania.

A section on applications of volume and adjustment tables is included. pine treatment substantially increased survival, which led to greater volume compared with bareroot longleaf pine.

Labially pine yielded more volume than longleaf pine on all sites but one, where survival was negatively affected by fire. Depth of sandy surface horizon affected mean annual height growth of both loblolly and longleaf pine.

Merchantable cubic- foot volume is determined as follows: V = (BH) - = ( X 72) - = 4, cubic feet From table 2 for an average stand diameter of inches, the conversion factor is criteria were for purity, defined as longleaf pine basal area (BA) that is 90% or more of plot BA, and even-agedness, as defined by a ratio between two calculations of stand density index.

The diagram predicts stand top height (mean of tallest 40 trees/ac) and volume (ft3/ac) as a function of quadratic mean diameter and stem density (trees/ac). Stem analysis data from loblolly pine (Pinus taeda L.) trees grown in cutover, site-prepared plantations across the South were used to develop total and merchantable cubic-foot volume.

The proposed model was biased for trees in the 2 and 3 inch diameter class, however, this bias was small(cubic foot). Residuals ranged from to cubic by: Sample trees ranged from 2 to 7 inches in diameter and from 18 to 40 feet in total height. Parameters for a segmented polynomial taper and compatible cubic foot volume equation were simultaneously estimated using a seemingly unrelated nonlinear fitting procedure to volumes based on a generalized Newton formula and an overlapping bolt by: The table presented here for natural shortleaf pine is based on total tree height and gives volume estimates for the commonly used 4- and 3-inch d.i.b.

The objective of this study was to develop models to predict longleaf pine tree diameter at breast height (dbh) and merchantable stem volume (V) using data obtained from field measurements.

The individual-tree biomass equations are applied to determine mass for each tree recorded on an FIA inventory plot. Tree mass and merchantable volume of growing stock are summed for each plot and expressed as densities (Mg/ha and m3/ha for mass and volume, respectively).Cited by: There are two schools of thought regarding how many longleaf pine seedlings should be planted per acre.

The 'plant-'em thick' school recommends planting more than trees per acre (TPA) while the 'plant-'em thin' school recommends planting less than TPA.

Some recommend planting container seedlings per acre (14 feet between rows and 7 feet between trees) if the. enhanced pine merchantable volume for eight years following treatment and enhanced pine straw production in the pine straw scenarios.
