Browse Surveys 



Browse surveys were carried out according to the method developed 

 by Passmore and Hepburn, 1955 (see Ont. Dept. of Lands and Forests, Research 

 Report No. 29). In most cases the original method was changed slightly in 

 the interest of simplicity for extensive use. Rather than estimating the 

 percentage of twigs browsed from each stem, the stem was merely recorded as 

 browsed or unbrowsed. Plots were the same as in the original method, one 

 chain long by two feet wide with five chains between plot centres. The 

 results of this survey are summarized in Table No. h.

 the browsed category. Therefore, figure is low. 

 *« Browsed twigs counted rather than just stems. Not comparable 

 with other figures.
