What size trees are used for pulpwood?

6-9” diameter
Pulpwood is typically a small tree measuring 6-9” diameter breast height (DBH). Pulpwood trees are chipped into small chunks, chemically treated, and made into paper. Pulpwood is measured by weight in tons or by volume in standard cords.

What size is pine sawtimber?

Pine sawtimber trees are used to cut dimension lumber (2”x 4”s, 2”x 6”s, 2”x 8”s, 2x 10”s, 2”x 12”s, 4”x 4”s, and 4”x 6”s in 8, 10, 12, 14, and 16 feet lengths). Pine chip-n-saw (CNS) trees have no visual defects, are relatively straight, and have dbh of 9 to 13 inches.

How do I calculate wood tonnage?

The conversion process is simple but requires assuming a ton- to-mbf conversion factor. If a hardwood conversion of 9 tons/mbf (Doyle) is assumed, then each ton has 111 board feet (1,000 board feet ÷ 9 tons/mbf = 111 bf):

How many cubic feet is a ton of wood?

1 ton (40 cubic feet) = 1.133 cubic metres.

What length do you cut pulpwood?

Tree size for forest products is expressed as diameter at breast height (DBH), which is measured at 4.5 feet above the ground on standing trees. Generally, Pennsylvania’s hardwoods become merchantable for pulpwood when they are 6 inches DBH or larger and reach sawlog size at 12 inches DBH.

How long does pulpwood have to be?

The conclusion reached from the facts and considerations outlined above was that from the forest working aspect the optimum length of pulpwood was 10-12 feet, with a downward tolerance.

How many cubic feet are in a ton of wood?

How do I calculate volume tonnage?

Multiply the volume of the material by its density to obtain the material’s mass. In this example, 500,000 x 705 = 352,500,000. You have 352,500,000 kg of rye. Divide the mass in kilograms by 907.18 to convert it to tons.

What kind of trees are used for pulpwood?

Monoculture of species intended specifically for pulpwood include loblolly and slash pines in the southern USA; various species of eucalyptus (most commonly Eucalyptus globulus and Eucalyptus grandis) in Latin America, Iberian Peninsula, Australia, south-east Asia and southern Africa and acacia (most commonly Acacia …

What is the volume of a loblolly pine stand?

An inventory was taken of a loblolly pine stand with sawtimber averaging 16 inches DBH. The volume estimate was 100 MBF Doyle pine sawtimber, 50 cords chip-n-saw, and 120 cords of pulpwood.

Are pine pulpwood prices going up or down?

There have been some periods of volatility since 2002 driven in part by the Great Recession and weather conditions, but pine pulpwood prices have continued to trend upward. On a Southwide basis, pine pulpwood prices are up 47% while pine sawtimber prices are down 35% since 2002.

What is the difference between Chip-n-saw and pulpwood?

Pines with DBH (diameter at breast height) ranging from 6 up to 26 inches can qualify for pulpwood. Chip-n-saw is a medium-valued timber product that yields two-by-fours and chips. Straight, clear stems with DBH from 10 to 14 inches can qualify for chip-n-saw.

Is pine lumber measured by weight or volume?

High-production pine sawmills have changed to weight scaling and buy timber by the ton (2,000 pounds). Mills producing fuel, chips, pulp, or paper are also mea- suring timber only by weight. However, high-grade pine lumber and specialty mills often still measure volume using the Doyle Log Rule and pay per MBF (1,000 board feet).
