J.D. King: Wolves Don’t Change Rivers 

HowlDoin

The wolves that were reintroduced to Yellowstone National Park in 1995 have not restored the landscape. They have not brought back the aspens and willows. They have not brought back the beavers or the songbirds. And no, the rivers have not changed, either

“Funny that you should ask,” replied Dr. Kay. “I just returned from Yellowstone National Park where I revisited many of my old research sites. Willows and aspen have grown taller at a few locations but there has not been any far reaching trophic cascade. The Lamar River and other streams have not recovered — in fact, the Lamar River in the Lamar Valley is worse than ever.”

Balance of Nature: “Has the Disadvantage of Being Untrue”

I’ve been doing a lot of reading over the past 3 or 4 days and during that time I came across a very interesting quote. The quote comes from a man named Charles Elton, perhaps best known among wildlife biologists as the father of ecology.

“It is assumed that an undisturbed animal community lives in a certain harmony….the balance of nature. The picture has the advantage of being an intelligible and apparently logical result of natural selection in producing the best possible world for each species. It has the disadvantage of being untrue.”
