“…The specifi c gravity for each tree species or group of species was determined at the Forest Service's Forest Products Laboratory and applied to FIA estimates in developing merchantable tree biomass (weight of tree bole). To calculate total live-tree biomass, we must add the biomass for stumps (Raile 1982), limbs and tops (Hahn 1984), and belowground stump and coarse roots (Jenkins et al 2004). We do not currently report live biomass for foliage.…”

The second full, annualized inventory of Maine's forests was completed in 2008 after more than 3,160 forested plots were measured. Forest land occupies almost 17.7 million acres that represents 82 percent of the total land area of Maine. The dominant forest-type groups are maple/beech/yellow birch, spruce/fi r, white/red/jack pine, and aspen/white birch. Total statewide volume equals 25.5 billion ft 3 , resulting in almost 590 million ft 3 of live tree volume grown each year. The report also contains additional information on sustainability, biomass, carbon, forest health, land use change, and timber products. DVD included in this report includes detailed information on forest inventory methods and the quality of the estimates found in fi ve detailed tables (Tables A-E). A complete set of core tables are contained on the DVD or can be found online: http://www.nrs.fs.fed.us/fi a/data-tools/state-reports/default.asp.

“…Earlier studies in volume estimation for different tree species involved number of different variables to estimate the volume. Tree biometric attributes such as tree height, bole height, diameter at breast height, basal area, top diameter over bark were used to calculate the merchantable volume (Hahn 1984). Cao et al (1980) compared volume ratio models and taper equation models to estimate the cubic volume prediction.…”

Teak plantations are generally managed for timber production and presently there is an increasing interest in understanding the carbon stocks of Teak plantation. A study was developed on carbon yield table for Teak in Cauvery delta zone of Tamil Nadu, India and field data was taken from 15 sample plots of 30 m × 30 m size in different age classes, for instance 4-5 years, 7-8 years, 12-13 years, 15-16 years, 18-19 years, 23-24 years, 40-41 years and 46-47 years, respectively. Tree height and diameter of 2 meter segments from ground level to top height were measured and the average merchantable volume of 1.246 m 3 and carbon content of 373.80 kg were recorded in the age class of 46-47 years. The carbon model constructed for Tectona grandis using multiple linear regression was Y = -113.001+2.8616(Age)-3.6946(Total height)+1245.813(Diameter). The carbon yield table was constructed using the age class, top height class and diameter class. The overall observation of the study concluded that, the best fit carbon yield models were developed for T. grandis with 91 per cent accuracy by comparing actual carbon stock and predicted carbon stock.
