Snyder Creek: Seedtree Cutting 



Description 



This 11-acre, north-slope tract was j ammer- logged in 1952 leaving about nine western 

 white pine seed trees per acre and some unmerchantable hemlock and grand fir. Slash 

 from the logging was piled and burned in 1953. The unmerchantable trees were felled in 

 1954 and the slash from these was also piled and burned. Mature timber bordered this 

 area on the north and west (fig. 14). 



Results 



Annual observations during the post- logging years showed that this area regenerated 

 rapidly to a variety of species with hemlock and western white pine the most abundant. 

 Most of the early western white pine reproduction was infected with blister rust. By 

 1956 Ribes eradication had reduced the infection source enough to permit good establish- 

 ment of relatively rust-free pine (fig. 15), but other species had gained in dominance. 

 For instance, reproduction measurements during 1959 showed that while 88 percent of the 

 area was stocked with western white pine, other species were dominant on 68 percent of 

 the plots.
