Harvesters 1 are used which fell, lop and cut the tree into blocks which are separated from the branches and the tops in one or more piles and collected using special transporters. For working each tree in conjunction with felling, the branches and tops are gathered into an essentially uniform and loose pile in which the branches and the tree tops have been placed in the same direction, and the loose piles are collected by special transport means.
