Natural regeneration response to initial treatments

Abstract

During the 1907 to 1911 harvest, logs were transported to landings by means of log chutes, horse skidding, and steam donkey yarding. Slash was disposed of by piling and burning, which the purchaser considered to be an unnecessary practice (Koch 1998). Usually this type of logging and postlogging treatment results in relatively light site disturbance, and the photo series tends to corroborate this. Some advance natural regeneration, primarily Douglas-fir, was present in the stand prior to logging; most of it became established in the 10 years prior to logging (Boe 1948). However, opening of the stand, site disturbance of the logging, and apparent good seed crops resulted in adequate subsequent tree regeneration. White (1924) stated: “Along about 1912, there was a heavy yellow pine seed crop. That fall, in October, the area was grazed close by sheep.” The most successful regeneration period was the first 10 years after logging, with a gradual decline in the second and third decades.
