By telling species and aiDprozimate 

 size. Example: "A 20-inch larch.'* 

 Size determined by ocular estimate. 

 Calling the estimated size enables 

 the tallyman to place the tree in 

 the proper stratum. Special care 

 should be taken in estimating 

 border-line trees so that the tree 

 count by strata will not be biased. 

 Measuring border-line trees vxill 

 prevent any bias. 



3. Tallynan: Count tree and 

 acknovjledge to marker that 

 tree is recorded. 



By putting a slant mark through 

 number one of the "tree count 

 numbers" on the appropriate tally

 addition say "measure it." 



6. Llarker; Lleasure d.b.h. and 

 estimate height and defect. 

 Number tree. 



D.b.ho measured to nearest inch vvith
