Additional Information

Cruise Instructions: Use the Sample Tree Ratio sample type. Record tree data for each plot starting with the first tree north using the Mobile Map application going clockwise, then upload data into ArcGIS Online when completed. Use the plot layout function in MobileMap to ensure plots are well-distributed throughout each stand/VDU. Default stump height = 0.5 feet. Mark each plot location with a stick in the ground with flagging attached, and also hang a 2nd piece of flagging nearby at about eye level, with the plot number written on the flagging.
