Willamette NF, Spatial Statistics Database

GIS scripts developed by IBP allow the user to define a list of map stations, the spatial extent of analysis, and a list of land cover class codes (or habitats) of interest. For instance, we provide the results of spatial analyses (FRAGSTATS) of USGS GAP and National Land Cover Datasets (NLCD1992, NLCD2001, and derived difference datasets) for multiple radii surrounding each MAPS stations in the region. This enables the user to extract spatial statistics by defining certain criteria (e.g. 4km radius statistics for deciduous forest habitat [41], shrub habitat [5], and agricultural land [8]) and absolute cover change over ten year period (1992-2001).

Instructions for retrieving spatial data

1. Select and copy the following Station Numbers of Willamette MAPS stations:

11157
11158
11159
11160
11161
11162
11263
11270

(See MAPSStationInfo.xls for associated station names, geographic locations, brief habitat descriptions, and monitoring function)

2. Click on the link to the dataset of your interest:

NLCD 2001-1992 Level I Reclass - link to FRAGSTATS query database.

NLCD 2001-1992 Level I Reclass Table (XLS) - explains reclassification of NLCD change product codes to signify habitat loss or gain between 1992 and 2001.

PNW GAP Level I Reclass - link to FRAGSTATS query database.

PNW GAP Level I modified Reclass Table (XLS) - Excel spreadsheet detailing a the modified Level I reclassification of USGS's Northwest GAP product. used in the spatial analyses.

3. Paste the station numbers in the "Station ID" Box

4. Press the "refresh tables" button to retrieve the subset of data for the Fremont stations.
