Special attention also needs to be paid to the cutting and use of roads and gaps in the forests, the transit of vehicles and machines, management of wastes of all kind and protection of fauna. Forest stewards direct operations and, in conjunction with the management of the concessions and the specialized professionals, they handle all forest-harvest processes. Most concessions currently have their own stewards, but those without use stewards contracted and coordinated by ACOFOP. The process makes it possible to optimize the yield of the wood and helps maximize the useful life of the sawmill equipment.
