Well one of the first questions I would ask about that study is whether the supposed risk of wolf attack actually does change the behaviour and distribution of Elk. If it doesn't then their results are meaningless.

 From that article:
"When Kauffman and his colleagues studied aspen in areas where risk of attack by wolves was 
high or low, they obtained results different from Ripple’s. Rather than look at the five 
tallest aspen in each stand, as Ripple had done, they tallied the average tree height and used 
locations of elk kills to map the risk of wolf attacks. By these measures, they found no 
differences between trees in high- and low-risk areas."

So some people are getting excited about tree regrowth that might be attributed 
to the presence of wolves, but others are arguing about whether there's been 
any regrowth at all.

Anyone else confused?

It's a fascinating narrative, but like most things maybe not as simple as it

A really interesting short clip on the benefits of wolves in Yellowstone N
P.
Perhaps a lesson that would translate to other areas...
