STUDY METHODS AND BASES 



The study was conducted on logging operations in 19^3 and 1951;. 

 Trees felled for logging at eight locations were used. Not many such 

 areas were available, but those used \<iere selected to give as nearly 

 as possible a representative distribution in Southeast Alaska, Five 

 of the study areas were located south of V'rangell where most of the 

 current logging x^ras being done, and three of the areas were further 

 north. 



Sampling was distributed to all available elevations within a 

 study area. The only selection of sample trees was for a good basis 

 in all representative diameter classes, ifestern redcedar was not 

 present in all study areas, and all of the felled trees of this 

 species on two areas were used as samples. 



The basis of study trees, by diameter classes, at each study 

 area is given in table 1. 



When possible, general notes were recorded on trees before they 

 were felled, and detailed notes were taken on all study trees after 

 they had been felled and bucked into logs. The extent and types of 

 c\ill, the causal fungi, and all associated cull indicators were deter- 

 mined and recorded on scale diagrams of each study tree.
