YOUNG GROWTH ON CUT-OVER LAND 



909 



la — Same with young growth on 60 per cent of area averaging 25 

 feet or over in height. 



lb — Remainder of class one. 



II. Class Two. — Partly stocked. — 10 to 60 per cent stocked with 

 second growth. 



III. Class Three. — Non-stocked. — Less than 10 per cent stocked with 

 young growth. 



It was found possible with very little additional work to secure con- 

 siderable other information on the character and quality of the repro- 

 duction. Accordingly the estimated percentage of the area of each 

 2 3/2 -acre plot covered with reproduction was recorded together with the 

 average height of the young growth. The species of young growth 

 that apparently would predominate in the next stand was noted. It 

 was found that many sound and thrifty young trees over 13 inches in 

 diameter, breast-high, and capable of producing considerable seed were 

 scattered about the area, and the number situated on each plot was 

 counted. In addition groups of timber of merchantable size that had 

 been left without cutting were cruised. 



From the results of this work a map was prepared showing the class 

 of stocking and the average height of reproduction for each 3^-acre 

 plot. The estimated percentage of stocking, age since cutting, and 

 number of thrifty trees over 13 inches in diameter were placed on large 

 sheets for a permanent record. Compilation of the data showed that 

 16.7 per cent of the cut-over area available for exchange was well 

 stocked, 52.4 per cent was partly stocked, and 30.9 per cent was not yet 

 restocking. In the well stocked class 2.6 per cent of the total cut-over 

 area had young growth averaging over 25 feet in height. The average 

 percentage of stocking, the average height and the average time since 

 cutting were computed for each class from the data for the 2^ -acre 

 plots. These averages are shown in the following summary :
