No methods recorded for this dataset

Dataset Fields

Detailed documentation of the fields comprising the dataset, including the type of measurement, units where applicable, and any controlled vocabularies or code lists present in the data

Field Name	Caption	Description	Additional Information
COUNT	COUNT	If 'LTCODE' = 'GT', 'COUNT'=1 (each tree coded individually). If 'LTCODE"='LT', 'COUNT' = the number of <10cm diameter saplings of that species in the plot.	Measurement type: Ordinal
DBH	Diameter at Breast-Height	Diameter at breast height in centimeters, if 'LTCODE'='LT', this field is coded as '0'.	Measurement type: Ordinal
ELEV	Elevation	Elevation of plot surveyed from in feet.	Measurement type: Ordinal
LIVEDEAD	Live/Dead	Whether the tree sampled is live or dead. L=live tree, D=dead tree.	Measurement type: Nominal
LOCATION	Location	Number code for each 'location' - or clusters of plots within an area of ~1 ha as outlined by the two transect methods used in the study.	Measurement type: Nominal
LTCODE	LTCODE	Size class descriptor. All trees with a diameter at breast height of >10cm are coded individually as 'GT', with their DBH recorded in the 'DBH' field. All trees with a DBH <10cm are tallied by species in the 'COUNT' field.	Measurement type: Nominal
PLOT	Plot		Measurement type: Nominal
SPECIES	Species	Species codes listed in methods, using three-letter codes for each species based on the common name.	Measurement type: Nominal
WS	Watershed	Two-letter code assigned to each watershed sampled in this study. Codes listed in methods.	Measurement type: Nominal

Stratified Random Sampling
Started: 1997-01-01
Ended: 2000-12-31
Stratified random sampling of 5 watersheds throughout the Catskill Mountain Preserve ranging in size from 63-476 hectares. Stands were sampled along a series of transects perpendicular to the stream axis, with sampling occurring at a randomly chosen elevation within each 100m elevation band. Stands sampled within each watershed were proportional to its area. Each stand consisted of 5 plots, 6 x 30 meters each. The five plots were places 20 meters apart along the contour line. DBH of all trees >10cm in the plot was recorded, and all stems <10cm and at least 1.6 meters tall were tallied by species. Organic horizon soils were collected for carbon-nitrogen analysis.

Stratified random sampling of 5 watersheds throughout the Catskill Mountain Preserve ranging in size from 63-476 hectares. Stands were sampled along a series of transects perpendicular to the stream axis, with sampling occurring at a randomly chosen elevation within each 100m elevation band. Stands sampled within each watershed were proportional to its area. Each stand consisted of 5 plots, 6 x 30 meters each. Five plots were laid out within a larger 58 x 90 meter rerctangle, one in each corner and one in the center. Elevation was recorded at the center plot for this method. DBH of all trees >10cm in the plot was recorded, and all stems <10cm and at least 1.6 meters tall were tallied by species. Organic horizon soils were collected for carbon-nitrogen analysis.
Tract Surveys
Started: 1997-01-01
Ended: 2000-12-31
Three tracts not necessarily comprising a watershed were sampled at stands at randomly chosen latitude and longitude coordinates evenly distributed across elevation. At each stand, four prism survey plots (metric wedge prism, BAF 2) were established within a hectare, one in the center of each quadrant. Species and DBH of each tree included by the prism were recorded. Organic horizon soils were collected for carbon-nitrogen analysis.
