"Elk Die After Gorging on Winter Wheat"

I don't know what this means, but it's interesting:

"The winter wheat did the young elk in because their digestive systems cannot break it down and absorb its nutrients. This means some elk actually died of starvation because they were not absorbing nutrients from the winter wheat.

"'They starved to death on full stomachs,' Kirsch said."

I guess killing off ruminants that would otherwise eat your seeds is effective at limiting predation.  But I don't understand why the elk seem to find wheat addictive.  Unless they have the same reaction that people do...  Very interesting.
