</blockquote><h2>Description</h2><blockquote>
<p>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.</p>
(1) Documented forest disturbance events are coded as:
<blockquote>
<p>1, selective logging prior to 1916<br>
2, clearcut logging prior to 1916<br>
3, clearcut logging and fire prior to 1916<br>
4, moderate (25–50%) canopy loss in a 1950 blowdown event<br>
5, severe (50–100%) canopy loss in a 1950 blowdown event<br>
6, moderate (30–60%) canopy loss in a 1995 blowdown event<br>
7, moderate or intenseley damaged (10-64% canopy loss) in a 1998 ice storm event</p>
</blockquote>
<p>(2) A look-up table for description of the bedrock types is available at <a href="http://www.nysm.nysed.gov/data/bedrock.txt">www.nysm.nysed.gov/data/bedrock.txt</a></p>
<p>(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.</p>
<p>(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.
