Globally, climate change and habitat loss are increasing “global greening.” While these changes benefit some species, animals such as woodland caribou may suffer in a greener world. We studied links between habitat alteration (e.g. forest cutting), primary productivity, moose, wolves and caribou across part of the Canadian Boreal forest. By studying all these components simultaneously, we found that habitat alteration led to more productivity, which in turn produced more moose and wolves, and precipitated caribou declines. Species like caribou, which are adapted to low productivity environments, however, are not expected to do well in a greener world.

James speaks at a pro-water rally on the steps of city hall on the eve of the disastrous council vote. More pics, below .
