Remember those last, precious 4,000 hectares. The plan is to preserve a few small isolated areas as parks, little biological Disneylands for tourists to visit and for scientists to sweat in. The entire forest is removed, first by bulldozing the trees. Very kindly, the miners will allow the scraps and timber to be used by the locals. Then the treeless topsoil is stockpiled in heaps to be replaced later.
Heaps create heat.
Even micro-organisms die. The next step is the dredging. Now dead topsoil is replaced and new trees are planted. Apparently these giants of industry think they can artificially replace 250 million years of evolution. Of course a lot of the area will not be replanted as 'natural' forest.
