All of this discussion has been focused on the dry forest of the ACG. However, the ACG also contains upper elevation cloud forest and lowland rainforest in its eastern side. There are abandoned pastures and fields in these wetter areas as well. Is the forest invasion process the same in them as in the lowland dry forest? No. In this infrared image of the eastern side of the ACG, the dry forest pastures (black if burned, pale if grass) are at the bottom of the image. Moving up the slopes onto the volcanos, the pastures extend into much wetter forest - rainforest and even cloud forest on the right side of the image. This particular photograph was taken on a relatively cloudless day, but on some days the clouds almost completely cover the red forest (in an infrared photograph, green leaves show as red).
