Figure 8.4 Ecological, social and economic impacts of felling hollow trees.

Fellers working in selectively logged forests in Borneo are faced with a dilemma when deciding whether or not to cut trees suspected to have internal defects that will render them not worth extracting (Figure 8.4). The uncertainty about whether standing trees will yield commercial timber, and the fact that most forest workers are paid principally on the basis of volumes of timber yarded to roadsides or log landings, leads to the tendency to fell all but the most obviously defective trees. Counterbalancing this tendency is the increased risk to the worker of felling trees with hollows and heartrots; when the expected ‘holding wood’ turns out to be rotten or absent, the consequences can be fatal. Less dramatically, fellers waste time and fuel felling trees that are then not harvested. Nevertheless, where merchantable timber is scarce, fellers might feel compelled to assume the risks and pay the costs of felling trees that are likely to harbour heartrots and hollows.
