Abstract
This paper investigates various operational considerations as they relate
to timber-marking tolerant hardwoods in north/central Maine. Specifically,
marking productivity is examined in terms of tolerant hardwood stand and site
conditions. Also, associated benefits and costs are studied.
Line of sight and marking crew sizes have the greatest affect on marking
productivity. A productivity equation of marking productivity (acres/man-hour)=
0.46 * line of sight +1.17 is the formula that describes how productivity values
vary with varying line of sight values. Marking crew sizes three and greater have
an average productivity of 2.65 acres per man-hour.
Marking significantly increases the present hardwood residual stumpage
value per acre. This is an increase of about thirty percent. Overall, the benefits
of marking far outweigh the costs in this study.
