It is important to realize that there are numerous costs associated with getting timber from the stump to the market. A skilled laborer cuts the tree; another skilled laborer in an $80,000 machine drags (skids) the log to a truck; another skilled laborer in a $30,000 machine loads the log onto a truck; a driver in a $100,000 truck hauls the log to the mill yard where it must be unloaded. All these costs, plus a profit margin must come out for a tree to pay its way to the sawmill. The farther the tree is located from the market, the more difficult it is to extrapolate a stumpage value.

Every dollar spent to get the log from stump to market is one less dollar available to pay for stumpage. Poor terrain and inaccessibility makes high-value timber worth less than under optimal conditions, and makes low-value timber almost worthless to the buyer if it does not cover the costs of hauling it out of the woods
