Numerator attribute number and description: 0201 Average annual net growth of sound bole volume of trees (at least 5 inches d.b.h./d.r.c.), in cubic feet, on forest land
Denominator attribute number and description: 0225 Average annual removals of sound bole volume of trees (at least 5 inches d.b.h./d.r.c.), in cubic feet, on forest land
This ratio estimate is based on the plot area that was forest land at both the beginning and end of the remeasurement period. This provides a more realistic ratio estimate of the actual change component (growth, removals, mortality) that has occurred on lands that remain in the forest land base.
FIADEF as the forest land definition.

Numerator Estimate Description

Average annual net growth volume in the sound bole of trees (at least 5 inches d.b.h./d.r.c.), in cubic feet, on forest land (for remeasured plots (V2 - V1)/(t2 - t1)) that occurred after deducting mortality volume. Because this value is net growth, it may be a negative number. Negative growth values are usually due to mortality (V2 = 0) but can also occur on live trees that have a net loss in volume because of damage, rot, broken top, or other causes.
Tree: A woody plant usually having one or more erect perennial stems, a stem diameter at breast height of at least 3.0 inches, a more or less definitely formed crown of foliage, and a height of at least 15 feet at maturity.
Forest land: Land at least 10-percent canopy cover by trees of any size, including land that formerly had such tree cover and that will be naturally or artificially regenerated. Forest land includes transition zones, such as areas between heavily forested and nonforested lands that are at least 10-percent canopy cover with trees and forest areas adjacent to urban and builtup lands. Also included are pinyon-juniper and chaparral areas in the West and afforested areas. The minimum area for classification of forest land is 1 acre and 120 feet wide measured stem-to-stem from the outer-most edge. Unimproved roads and trails, streams, and clearings in forest areas are classified as forest if less than 120 feet wide.

Denominator Estimate Description

Average annual sound cubic-foot removals on forest land. Trees that were live and on forest land at the time of the previous inventory and were removed from forest land by the time of the current inventory.
Footnote: Removals are cut and utilized trees, trees killed as a result of harvest operations but not utilized, and live trees associated with land-use reclassifications.
Tree: A woody plant usually having one or more erect perennial stems, a stem diameter at breast height of at least 3.0 inches, a more or less definitely formed crown of foliage, and a height of at least 15 feet at maturity.

Page classification variable description

No pages selected.

Row classification variable description

Congressional district code. A territorial division of a State from which a member of the U.S. House of Representatives is elected. The congressional district code assigned to a plot (regardless of when it was measured) is for the most recent Congress (112th Congress in 2011-2012); the assignment is made based on the plot's approximate coordinates. CONGCD is a four-digit number. The first two digits are the State FIPS code and the last two digits are the congressional district number. If a State has only one congressional district, the congressional district number is 00. If a plot's congressional district assignment falls in a State other than the plot's actual State due to using the approximate coordinates, the congressional district code will be for the nearest congressional district in the correct State. This attribute is coded for the coterminous States and Alaska, and is left blank (null) in all other instances.

Column classification variable description

Owner group major - ownership codes are collapsed into Public and Private categories.
