Data description: Seward Peninsula Tree Establishment Data 

   This file contains data on white spruce recruitment history at
treeline sites on the Seward Peninsula.  Specific site
descriptions, including elevation, latitude/longitude, and
general descriptions of vegetation, can be found in the
metadata file (REC_ _META.CSV).  In general, though, two areas
were sampled.  Trees were sampled along the floodplain of Bear
Creek (a tributary of the Niukluk River) and in adjacent
tundra.  These sites are Bear Creek Floodplain and Bear Creek
Non-floodplain, respectively.  Four sites were sampled along
the Fox River, ranging from a site at the low end of the
forest-tundra ecotone (Sandy Bridge) to a site at the uppermost
limit of the forest-tundra ecotone (Horton Creek).  The data in
the file are the number of trees (reported on a per hectare
basis) that established during each of the 10 year periods
identified in the file.  The first column identifies the end of
the 10-year time period (i.e., 1710 indicates the period from
1701-1710).  Columns 2-7, identified according
