Tree Topwood Estimates In Hardwoods

A 12 inch two log tree growing one log and 4 inches in 10 years or five rings per inch radial growth is increasing at 10 1 percent.

Tree topwood estimates in hardwoods.

Use top headings to enter growth estimate number of merchantable16 foot logs and either 10 year dbh growth or number of rings per radial inch. The wood from hardwood trees tends to be harder because the trees grow at a slower rate giving the wood its greater density. A 19 6 inch tree rounds up to 20. Hardwoods grow at slower rates than softwoods which makes them denser.

Hardwood broadleaf deciduous trees tend to grow best in loamy soils a mixture of sand silt and clay. A hardwood tree s value as pulpwood usually depends on its volurne seldom on its species so the lake states composite volume tables provide an excellent base for convert ing tree volumes to standing tree values. Estimates from this chart assume that you utilize the main stem and all limb wood until limb diameter reaches 4 inches. We re not interested in the overall tree height just the point at which the trunk narrows to 8 inches or where the tree contains too many.

Follow our three part guide to estimate the value of your standing timber. A standard cord is a four foot by four foot by eight foot stack of wood. A board foot is a wood plank that measures one inch by 12 inches by one inch. A log rule is a tabular system used in determining the net volumetric yield of a log.

Fter we have the diameter of the tree we need to estimate it s height. Most common hardwoods unlike the conifers or softwood firs spruce and pines hardwood trees have evolved into a broad array of common species. Many conifers do just fine in heavy clay or well drained sandy soils and can tolerate dry southern exposures better than most hardwoods. A tree that measures 18 9 inches will round down to 18 inches.

Hardwoods are also characterized by distinct grain patterns and variations of color which make them aesthetically attractive. Mbf means thousand board feet. Tree diameter is measured at 4 5 ft above ground and defined as diameter at breast height or dbh. The reason is due in large part to the unique composition of hardwood trees.

Denser wood is harder stronger more durable and usually lasts longer. One cubic foot is equivalent to a 12 foot by 12 foot by 12 foot solid cube of wood. Calibrated for particular log scales. Board footage estimates for standing trees can be performed using a biltmore stick diameter tape clinometer and hypsometer.

All that is needed is to multiply the composite tree volumes by appropriate stumpage values. Use this table to estimate the amount of firewood available in a tree of a certain diameter. As a rule conifers can withstand adverse conditions better than hardwoods.
