Description: Site preparation is often necessary to obtain adequate forest regeneration, but inappropriate treatment may reduce subsequent growth. Broadcast-burned and piled-and-burned plantations were studied in southwestern Oregon to determine if burning method affected the growth of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco var. menziesii). The measured and potential heights of 5-year-old seedlings were about equal where broadcast burning occurred, but measured heights were less than potential heights on most of the piled-and-burned plantations. Site quality probably is damaged by piling and burning.

Keywords: Site preparation, regeneration, seedling growth, plantations
