Tree survival and growth as well as soil characteristics resulting from logging residue levels and site preparation treatments on Trout Creek Hill Units 1-3, Wind River Experimental Forest

Three units of old-growth timber were cable logged in 1974-1975 on Trout Creek Hill, Wind River Experimental Forest in southwestern Washington to test the effects of retaining different levels of logging residue and the effectiveness of 5 site preparation treatments on the growth and survival of containerized and bareroot stock types of Douglas-fir seedlings with different planting methods (hoe versus shovel). Details regarding the management of the logging residue via timber sale contracts and the costs of achieving the goals were published (Adams 1980a and Adams 1980b). Each of the three units, which represented different levels of logging residue, were divided into 15 plots. This data publication contains the subplot-level data collected in each 5 acre treatment plot such as tree height, diameter, and conditions noted 3, 10, and 20 years after planting. In addition to these data, some chemical and physical soil characteristics were subsampled in 1999. The 20-year survival, growth, and soil characteristics of this study were reported in Piatek et al. 2003.
Researchers wanted to test the effects of various methods of establishing young-growth plantations after logging stands of old growth.
