APPENDIX A 



TYPICAL INSTRUCTIONS FOR MEASURING AND 

 RECORDING TREE DATA 



Samples of field procedures that have been used to obtain data for processing by 

 NETVSL may be helpful to some users of this program. These procedures have been 

 developed for use under certain of the programed options, and according to decisions on 

 standards of accuracy that were appropriate for the immediate purpose of a particular 

 analysis. Hence, many of these procedures are more restrictive than the program re- 

 quires. For instance, the opportunity for grade classification is not used explicitly 

 in either example shown below. When questions arise in interpreting these sample 

 instructions, the answers should be sought in the main body of this paper. 



The following examples also contain useful test data for new users of NETVSL.
