DESCRIPTION OF DATA 



Ten species distributed among 10 habitat types are represented m the data 

 (table 1) Distribution of samples with respect to height and d.b.h. are shown by 

 species in figure 1, and by habitat types in figure 2. Periodic diameter growth 

 (inside bark), AO, was measured concurrently with periodic height growth, LH , tor the 

 most recent 10-year period. Values for height {H) and diameter at breast height (Z?)_ 

 Sere dSerminedas tEey existed at the start of the increment period because the regres- 

 sion estimate is required to predict the change in height as a function of height, 

 diameter, and projected diameter increment (inside bark). Of necessity, the crown ratio 

 used was observed at the end of the growth period. Fortunately, crown ratio changes 

 very slowly within 10 years. 



The trees were measured during the inventories of 1969-1972. Consequently, their 

 most recent 10-year growth is influenced by the climate and other temporal events from 

 about 1959 to 1972. 



l^Bark increment was not deducted when past d.b.h. was calculated. The slight 

 overestimate of past d.b.h. can cause only a slight bias in the estiamte of height 

 growth.
