But here's where it gets really interesting. The wleovs changed the behavior of the rivers. They began to meander less. There was less erosion. The channels narrowed. More pools formed, more rflife sections, all of which were great for wildlife habitats. The rivers changed in response to the wolves, and the rsaeon was that the rregeeannitg forests stabilized the banks so that they collapsed less often, so that the rivers became more fixed in their course. Similarly, by driving the deer out of some places and the vegetation recovering on the valley sides, there was less soil erosion, because the vegetation silazitebd that as well. So the wolves, small in number, transformed not just the ecosystem of the Yellowstone nitanoal Park, this huge area of land, but also its pahsiycl geography.

Original Text

But here's where it gets really interesting. The wolves changed the behavior of the rivers. They began to meander less. There was less erosion. The channels narrowed. More pools formed, more riffle sections, all of which were great for wildlife habitats. The rivers changed in response to the wolves, and the reason was that the regenerating forests stabilized the banks so that they collapsed less often, so that the rivers became more fixed in their course. Similarly, by driving the deer out of some places and the vegetation recovering on the valley sides, there was less soil erosion, because the vegetation stabilized that as well. So the wolves, small in number, transformed not just the ecosystem of the Yellowstone National Park, this huge area of land, but also its physical geography.
