Description

Abstract Professional foresters in Maine were surveyed regarding how and under what circumstances they designated trees for harvest. In addition, Maine's professional loggers were surveyed as to the relative silvicultural outcomes and operational efficiencies of marking/not marking trees prior to harvest. Results indicated that 46 percent of partial harvests administered by forester-respondents were marked prior to cutting, primarily to control the quality of the residual stand. The primary reason for not marking trees prior to partial harvest was that loggers did a good job of selecting trees to cut. In addition, it was apparent that, although some foresters said that they always marked partial harvests, the decision to mark/not mark trees prior to partial harvest was situational for many foresters in the state. Logger-respondents appeared equally divided on whether marking trees before harvest resulted in more or less efficient logging, irrespective of whether trees were felled by chain saw or by feller-buncher or mechanized harvester. However, while over one-third of loggers said that, in their opinion, the quality of silviculture was better when trees were marked, 46 percent said that they did not feel that marking had an effect on the quality of silviculture.
