Extinction of Giant Mammals Changed Landscape Dramatically

The last breaths of mammoths and mastodons some 13,000 years ago have garnered plenty of research and just as much debate. What killed these large beasts in a relative instant of geologic time?
A question asked less often: What happened when they disappeared?
A new study, based partly on dung fungus, provides some answers to both questions. The upshot: The landscape changed dramatically.
"As soon as herbivores drop off the landscape, we see different plant communities," said lead researcher Jacquelyn Gill of the University of Wisconsin, Madison, adding the result was an "ecosystem upheaval."
Gill and her colleagues found that once emptied of a diversity of large animals equaling or surpassing that of Africa's Serengeti, the landscape completely changed. Trees once kept in check by the mammoth gang popped up and so did wildfires sparked by the woody debris.

Ahhh...the Cenozoic. My favorite. Much more fascinating than rehashing all that reptilian crud. Give me giant mammals any day.
Dinohyus. Now there was a beastie.

Imagine the carbon footprint of these giant beasts. The Clovis people must have killed them off to prevent global warming and boiling of the oceans. Good riddance.

Anyone that raises livestock knows what happens when pasture land is left ungrazed, it grows up in brush and finally trees. It only takes a few years as I've seen land that I once plowed now covered in trees several inches in diameter.
Another fifty years and no one will ever guess that the soil there was ever turned.
On the other hand place hogs in a lot and they'll kill every plant there in a short time.
Now where do I collect my grant money?
