Some aspects contribute to the increase of resin tapping costs and, hence, to the reduction of resin yield, namely: the limitation on the diameter of the trees to be tapped imposed by the Portuguese legislation; low stand densities; the necessary control of understory vegetation. Hence, it is essential to evaluate if and how some pine forest management parameters affect the total production of pine resin so it can be increased through silvicultural practices and, thus, compensate for the rise in some costs associated with the resin activity.
The influence of silvicultural practices on resin production: stand density, tree diameter, and use of controlled fire
