FolNdata.txt

Description

The file FolNdata.txt contains the full data set used in the source paper. This data set is inclusive of all independent variables, foliar N data, and species composition measurements collected at each of 75 plot locations in the Adirondack Park. The combination of the foliar N data and the relative species abundance data are used to make the canopy N measurement at each plot. The user should note the following.

(1) Documented forest disturbance events are coded as:

1, selective logging prior to 1916
2, clearcut logging prior to 1916
3, clearcut logging and fire prior to 1916
4, moderate (25–50%) canopy loss in a 1950 blowdown event
5, severe (50–100%) canopy loss in a 1950 blowdown event
6, moderate (30–60%) canopy loss in a 1995 blowdown event
7, moderate or intenseley damaged (10-64% canopy loss) in a 1998 ice storm event

(2) A look-up table for description of the bedrock types is available at www.nysm.nysed.gov/data/bedrock.txt

(3) Species abbreviations follow the convention of USDA species code (http://plants.usda.gov) and generally are the first two letters of the genus and first two letters of the species.

(4) Canopy N values for two plots with "no data" for Soam represent the weighted average from all other species in the plot. Soam (Mountain-ash) leaf samples collected in these two plots were lost during sample processing.
