Permanent Sample Plots. 43 



PERSONNEL. 



The crew should consist of three men preferably all with technical train- 

 ing. The work on the plots should be divided and done in the following 

 order. 



1. Surveying. Placing the large corner posts and the stakes along the 

 outside lines. Any small error in closure on the last line should be pro- 

 portioned between all of the stakes on that line; where the error of closure 

 is over i in 100 the lines should be re-run. After the outside lines have 

 been adjusted the stakes across the narrow side of the plot should be set 

 sub-dividing the area into one chain squares. 



2. Measurements of individual trees. One man should place the numbers 

 on the trees and do the calipering, the second man taking the heights and 

 the man in charge writing the data as they are given to him and writing 

 the trees description and health. 



3. Mapping. The man in charge of the party should do the mapping 

 with the traverse board while the two assistants locate the various features 

 by pacing. 



4. Contours. These should be mapped last since the position of the 

 trees, brush piles, etc., greatly assists in their location on the map. Unless 

 the topography is unusually steep, a 5-foot contour interval should be used. 



5. Seedling counts. These can be made after the one chain squares have 

 been established. 



6. Reports. The reports should be made after all of the other work on 

 the plots (including the photographing) has been done, usually in the field. 



PHOTOGRAPHS. 



In making a photographic study of the plots at the time of measure- 

 ment it must be understood that these photographs show the condition of 

 the plot only during its dormant period and another series should be made 

 during the growing period.
