Number of Accessible Number of Accessible Forest Land ConditionsForest Land Conditions
Record the number of forested conditions on the plot.
Number of Tree EntriesNumber of Tree Entries ChangedChanged
• Only includes trees and saplings (on both subplots and prism points)

Horizontal Distance to Horizontal Distance to Improved RoadImproved Road
ChangedChangedCodes are now one-digit categories:
1 100 ft or less
2 101 to 300 ft
3 301 to 500 ft
4 501 to 1000 ft
5 1001 to 0.5 mile
6 >0.5 to 1 mile
7 >1 mile to 3 miles
8 >3 miles to 5 miles
9 Greater than 5 miles
Horizontal Distance to Urban Horizontal Distance to Urban or Built-Up Land or Built-Up Land
ChangedChanged
Use the new one-digit distance codes used for distance to improved road.
Horizontal Distance to Horizontal Distance to Agricultural LandAgricultural Land
ChangedChangedUse the new one-digit distance codes used for distance to
improved road.
Size of Contiguous Forest LandSize of Contiguous Forest Land
Record the code that indicates the size of the contiguous forest around plot center using only the
photo on which the plot is located.
GPS CoordinatesGPS Coordinates ChangedChanged
Attempt to average 180 readings
Attempt to keep error reading no more than +/- 70 feet
Elevation is recorded in feet above mean sea level
Option of reporting offset coordinates within 200 feet of plot center
GPS UnitGPS Unit New ItemNew Item
0 GPS coordinates not collected
1 Rockwell PLGR
2 Other brand capable of field averaging
3 Trimble GeoExplorer or Pathfinder Pro
4 Recreational GPS (Garmin, Magellan, etc.)
Only record code 0 if coordinates cannot be collected at all within 200 feet of PC (unit is damaged, heavy canopy cover, mountain coves, no GPS unit available, etc.)
Always record readings collected within 200 feet of PC, even if less than 180 readings are obtained or even if error reading is more than +/- 70 feet.
GPS Serial NumberGPS Serial Number New ItemNew Item
Record the six-digit serial number of the GPS unit
Latitude/LongitudeLatitude/Longitude
Record the latitude and longitude to the nearest 100th second
Example:36° 47’ 05.25”
086° 34’ 29.51”
GPS ElevationGPS Elevation ChangedChanged
Now measured in feet above mean sea level
GPS ErrorGPS Error New ItemNew Item
• Record error reading of the averaged coordinates
• Make every effort to collect readings with less than or equal to 70 feet of error
• Record coordinates if cannot obtain an error reading less than +/- 70 feet
Number of ReadingsNumber of Readings New ItemNew Item
• Record number readings averaged
• Make every effort to collect 180 readings
• Record coordinates if cannot obtain 180 error readings
Azimuth and Distance to PCAzimuth and Distance to PC New ItemNew Item
• Leave blank if using a PLGR, even if coordinates are range-calculated.
• We are not using this in the South as long as we are using PLGRs.
