Below you will find a list and description of the files included in this data publication.

VARIABLE DESCRIPTION FILE (1)

1. \Data\_variable_descriptions.csv: Comma-separated values (CSV) file containing a list and description of variables found in all data files. (A description of these variables is also provided in the metadata below.)

Columns include:

Filename = Name of data file
Variable = Name of variable
Units = Units (if applicable)
Precision = Precision (if applicable)
Description = Description of variable


DATA FILES (4)

1. \Data\Codes_Condition.csv: CSV file containing a list and description of the condition codes used in all data files.

Variables include:

TreeCondCode = Code as it appears in the data files

Description = Condition code description


2. \Supplements\Codes_Species.csv: CSV file containing a list and description of the species codes used in all data files.

Variables include:

SpeciesCode = Code as it appears in the data files

CommonName = Species common name

ScientificName = Species scientific name


3. \Data\Data_CrawfordCreek.csv: CSV file containing tree measurement and condition data from the Crawford Creek site of the Levels-of-Growing-Stock study.

Variables include:

Block = Block identifier number (1-3)

Plot = Plot identifier number (1-18)

GSL = Growing stock level. Plots were thinned to six GSLs - 30, 60, 80, 100, 120, and 140 square feet of basal area per acre when the quadratic mean diameter is at least 10 inches.

Tree = Tree identifier number

Species = Tree species identifier (122 = ponderosa pine, 73 = western larch, 15 = white fir)

YrMeas = Year of measurement

StandAge = Stand age in years at time of measurement

DBH = Tree diameter at breast height to 0.1 inches

Height = Total tree height to 0.1 feet

HLC = Height to base of live crown to the nearest foot

Condition1 = Tree defects, heath issues, or mortality (see code descriptions in \Supplements\Codes_Condition.csv)

Condition2 = Additional tree defects, health issues, or mortality status if multiple conditions were reported (see code descriptions in \Supplements\Codes_Condition.csv)

CutClass = Plots are thinned to maintain pre-defined plot basal area per acre prior to next measurement period. As a result, trees that will be thinned to achieve this objective are marked. The number indicates which thinning occured, i.e. 1 = first thinning, 2 = second thinning, etc.


4. \Data\LookoutMT_Data.csv: CSV file containing tree measurement and condition data from the Lookout Mountain site of the Levels-of-Growing-Stock study.

Variables include:

Locale = Locale is a unique identifier, defined internally, that identifies groups of plots within each location within a given region.

Plot = Plot identifier number (119-136)

GSL = Growing stock level. Plots were thinned to six GSLs - 30, 60, 80, 100, 120, and 150 square feet of basal area per acre when the quadratic mean diameter is at least 10 inches.

Tree = Tree identifier number

Species = Tree species identifier (122 = ponderosa pine, 73 = western larch, 15 = white fir)

YrMeas = Year of measurement

StandAge = Stand age in years at time of measurement

DBH = Tree diameter at breast height to 0.1 inches

Height = Total tree height to 0.1 feet

HLC = Height to base of live crown the nearest foot

Condition1 = Tree defects, heath issues, or mortality (see code descriptions in \Supplements\Codes_Condition.csv)

Condition2 = Additional tree defects, health issues, or mortality status if multiple conditions were reported (see code descriptions in \Supplements\Codes_Condition.csv)

CutClass = Plots are thinned to maintain pre-defined plot basal area per acre prior to next measurement period. As a result, trees that will be thinned to achieve this objective are marked. The number indicates which thinning occured, i.e. 1 = first thinning, 2 = second thinning, etc.
