METHODS 



The studies consist of five reproduction cuttings made between 1935 and 1937, and 

 two that were made about 1951 (fig. 1). Treatments tested were strip clearcutting , 

 shelterwood cutting, seedtree cutting, and selection cutting, each within the Abies 

 grandis/Pachistima and Thuj a-Tsuga/Pachistima habitat types, roughly equivalent, in the 

 study area, to southerly and northerly aspects, respectively. Reproduction was 

 inventoried on permanent transects at intervals ranging from 2 to 7 years after the 

 initial regeneration cutting. Surveys generally consisted of an examination of species' 

 occurrence on 4-milacre (1/250-acre) quadrats located along the transect lines, and a 

 complete tally of seedlings on a 1-milacre (1/1000-acre) subsample of each 4-milacre 

 unit. The percentage of 4-milacre units containing one or more trees (the "4-milacre 

 stocking") provides an estimate of seedling distribution while the 1-milacre seedling
