SILVICULTURAL HISTORY 



The study site was located in the Benton Creek drainage of the Priest River Experi- 

 mental Forest (PREF) . In 1940 a strip clearcut, 330 ft (101 m) wide was extended from 

 the ridge on the south side of Benton Creek and up the opposite slope to the ridge on 

 the north side of Benton Creek (fig. 15 2). The clearcut was harvested with a conven- 

 tional "jammer" cable system: slash from the cutting operation was hand piled and burned. 



Original timber on the north slope consisted of young mature western redcedar 

 (Thuja pliaata Donn) , western hemlock (Tsuga heterophylla [Raf.] Sarg.), western white 

 pine (Pinus montiaola Dougl.), grand fir (Abies gvandis [Dougl.] Forbes), and western 

 larch (Larix occidental-is Nutt.). The south slope was stocked with young mature timber 

 of three species--ponderosa pine (Pinus ponderosa Laws.), Douglas-fir (Psuedotsuga 

 menziesii var. glauaa [Beissn.] Franco), and western white pine.
