6 wolves per 100 km sq seems to be the threshold for caribou populations....according to Canada researchers.
Fifty years ago there were as many caribou in Washington as moose. Now moose numbers exceed 1,000 and caribou are on the verge of extinction in Washington.
Habitat Largely Irrelevant? I have to be kidding right? Well, Banff and Jasper National Parks in the central Canada contained some of the most spectacular wildlife habitat in North America but today it is largely a game-less country due to predation. Approximately 40 years ago, wolves re=colonized parks that already contained grizzlies, black bears and mountain lions. The addition of wolves to the system has just about eliminated the moose and reduced elk populations by 80% or more. It's important to remember that the wildlife in Banff and Jasper are not hunted. Wolves have also caused elk herds to abandon large portions of their pre-wolf ranges. The habitat is still their, but the elk are not. And unlike our Park Service and Fish and Wildlife Service, who contend that predators have little effect on game populations, Parks Canada fully acknowledges what has transpired!

On average, 70 elk die from cars or trains each year."70 out of 350 killed by vehicles? That's 20% Just a guess, but I'd bet trains were responsible for the greatest portion of that. In Alaska, in the winter, trains take a horrible toll on moose, as when the snow gets deep and makes travel hard for animals, they naturally move on to the railroad right of ways to get around as those are kept clear for the trains. Then as the trains navigate down the tracks the moose are trapped by high snow banks and are literally slaughtered by the hundreds in bad winters. I could see the same thing happening in Banff.Then this on another web page ....."Banff MooseMoose are on the decline in the park, due in part to a deadly liver fluke, the return of wolves after a long absence, and an unnaturally high number of deaths on the railways and highways. However, you still have a good chance of spotting a moose"There's those pesky vehicle accidents again."Banff DeerThe park is home to both whitetail and mule deer, and both are common along the Vermilion Lakes Drive and the Bow Valley Parkway, particularly in the spring. ""Banff BighornSheep Bighorn sheep are abundant throughout the park, and are most commonly seen along the Bow Valley Parkway at Backswamp, on the Mount Norquay and Lake Minnewanka roads, and at the top of the gondola ride on Sulphur Mountain."Doesn't sound like there is a shortage of animals in Banff because of wolves. Are cervids at an all time high? no. Are they at an all time low? no
Control often equals dispersion. More for Washington?
Turns out you cannot, which was known back in ’87 when the wolf recovery plan was first written, you cannot control wolf population by hunting or trapping. If you want to control it, you need to poison them and get in there with helicopters and use helicopter gunships on them. Neither of which are popular with certain groups, if you can imagine. So the hunt in Idaho they had, half the wolves that were killed were in places the state fish and game agency had no idea there were any wolves."

But the real secret is, most wolves die from accidental causes, malnutrition, or intraspecific competition ie killed by other wolves. In may ways, wolves are self limiting. They don't have an easy life.
Yellowstone doesn't have the habitat to support more than 5000 elk, everyone knows that Wait your telling me there were once 17000-25000 elk, well winter kill is the reason 70-90% of the population died So many ways to spin it except admitting wolves are the root cause, along with a small small percentage of other factors
