Haynes Creek: Shelterwood Block 



Description 



Horse-logging on this 15-acre block in 1936 removed most of the associated species, 

 leaving a nearly pure western white pine shelterwood. Slash was piled and burned in 

 1936 and 1937. The light intensity in this shelterwood was probably less than 50 

 percent. The establishment report states that the canopy was denser than in either 

 of the previously mentioned shelterwood stands. The area lies on a very steep lower 

 slope with south- to west-facing aspects. Mature stands border the area on all sides. 

 The survey transects were located so as to sample reproduction separately on the 

 westerly ( Thuj a - Tsuga / Pachistima habitat type), southwesterly, and southerly (both 

 Abies grandis / Pachistima habitat type) exposures (figs. 9, 10, 11). 



Results 



Regeneration of the Haynes Creek shelterwood block has been slow. Stocking of all 

 species combined reached a satisfactory level within 10 to 15 years on the more favor- 

 able westerly aspect and within 19 years on the more severe southerly exposure; however, 

 stocking was not yet adequate after 19 years on the very unfavorable southwest exposure 

 (fig. 10). Individual-species regeneration followed a similar pattern. Both grand fir 

 and Douglas-fir were generally more abundant and had better stocking than western white 

 pine, although seed for these species had to come primarily from adjacent stands. 

 Hemlock reproduction was restricted to the moist lower slopes.
