Attribute:

Attribute_Label: pole length

Attribute_Definition:

pole length in feet - the tallest pole that the tree could be, based on dbh and length; sometimes there is a length here, but the notes column will say NO POLE in which case there is no actual pole because it did not meet ANSI standards

DATA FILES (9)

Below you will find a list and description of the data files included in this data publication. (Variable descriptions are also included in the Entity and Attributes detail section of this metadata file.) The main data file is RLGS_final_data_set.csv, but there are also several accessory data files including soil horizons, soil nutrients needle fall, and pole data.


1. \Data\Needle_fall_for_1992-1997.csv: Comma-delimited ASCII text (CSV) file containing fallen needle data collected between 1992 and 1997 on the RLGS plots. Variables are described below.

Plot: plot number

Direction: cardinal direction where the needle fall trap was located; there were either 3 or 4 traps on the plots sampled
n = north
e = east
s = south
w = west

Dry wt & bag: weight in grams of the dried needles and bag weight (“.” = data were lost)

Bag wt: dry weight of the bag in grams (“.” = data were lost)

First date: calendar date in month day and year (MMDDYY) when the collection started; example 70892 means the needle fall collection started on July 8, 1992

Collection date: calendar date in month day and year when the needle fall was collected

Note: the needle fall traps measured 3 feet by 3 feet and were set up on stakes 2 to 3 feet above the ground. Efforts were made to collect the needle fall every 4-5 weeks. If the data under the Dry wt & bag column is “.” then the data were lost for some reason.



2. \Data\Pole_data.csv: CSV file containing pole classification of trees on the RLGS plots. Variables are described below.

Plot: plot number

Tree: tree number

Pole: if value = 0 the tree did not make a pole; if value = 1 the tree could make a pole based on diameter at breast height (dbh) and form

Defect Ht: height in feet on the tree at which it could no longer be included if merchandised as a pole

DBH: diameter at breast height (diameter of tree at 4.5 feet) in inches

Crown Ht: crown height in feet

Total Ht: total tree height in feet

Age: ring count at dbh plus 7 years

Pole Class: pole classification (1-10) given based on dbh and length of pole (no description of these levels was provided, but we assume these are ANSI pole classes)

Pole Length: pole length in feet - the tallest pole that the tree could be, based on dbh and length; sometimes there is a length here, but the notes column will say NO POLE in which case there is no actual pole because it did not meet ANSI standards

Notes: Textual notes – if the column says “NO POLE:NO CLASS FITS” this means based on dbh and/or length, the tree could not make a pole based on ANSI standards

Tree No: tree number, numbered consecutively from north

Azimuth: azimuth from plot center in degrees

Distance: distance from plot center in feet

Crown Class: where the tree stood in the canopy in relation to other trees
1 = dominant tree
2 = co-dominant tree
3 = intermediate
4 = suppressed
5 = indicates the tree was at least 10 years older than the average dominant and co-dominant tree on the plot and this tree was not to be used for the calculation of plot site index

Fate: fate of the tree
0 = tree was alive
5 = tree was dead

Cut: if cut = 9 then the tree was to be cut; if fate = 5 then cut = 5
0 = tree was not cut
5 = tree was dead (cut = 5)
9 = tree was to be cut

Sample: type of sample
0 = tree was measured for crown ht and total ht
4 = tree was not sampled
If the tree had died (fate = 5), then the sample column gives the cause of death, where:
1 = lightning
2 = insects
3 = disease

7 = trespass cutting
8 = suppression
9 = unknown cause

Before Age: before cut average age for the dominant and co-dominant trees on the plot

After TPA: after cut trees/acre if the plot needed to be cut

After BA: after cut basal area in the plot needed to be cut. This happened when the “Before BA” was 7.5 square feet/acre greater than the assigned basal area for the plot, or if a change had been made to the assigned basal area class for the plot.

After Age: after cut average age for the dominant and co-dominant trees on the plot



5. \Data\RLGS_plot_coordinates.csv: CSV file containing plot coordinates for the RLGS plots. (Not all plot coordinates are known.)

Plot: plot number

Direction: soil depth taken in the cardinal directions at 10-feet from plot center
N = north
E = east
S = south
W = west

Depth1: each horizon for a plot and direction starts at 0 inches and the depth in inches is recorded to the next change in texture. That depth is then placed in the next row under the Depth1 column.

Depth2: depth in inches to the next change in texture

Example for Plot 1 and the east direction, the first horizon was 6 inches (”), the second horizon was 4” (from 6” to 10”), the third horizon was 9”, from 10” to 19”, the fourth horizon was 10”, from 19” to 29” and the final horizon was 36”, from 29” to 65”. We were unable to go any deeper given the equipment available.

Plot: plot number

Carbon (%): percent of carbon

Nitrogen (%): percent of nitrogen

Calcium (parts per million): calcium parts per million (ppm)

Magnesium (parts per million): magnesium ppm

Phosphorus (parts per million): phosphorus ppm

Manganese (parts per million): manganese ppm

Aluminum (parts per million): aluminum ppm
