Latest report shows NO association between number of wolves in Wyoming and the number of livestock depredations-
Wyoming Gray Wolf Recovery Status Report. U.S. Fish and Wildlife Service. Sept. 27 through Oct. 1, 2010
Although the report makes no mention of this, the report includes detailed graphs of wolf population and livestock losses to wolves over the years. Look at figure 1 in the report. If you take out one exceptional data point (a large sheep depredation in the Bighorn Mountains in 2009), there is no association between wolf numbers and depredations numbers since 2006. There was a trend until that time.
This is important because we hear from USFWS and others something like this Ad nauseum, “The good locations for wolves are all taken. As the population of wolves expands, conflicts with livestock will increase and at an accelerating rate.” [note that this not a actual quote, but a summation of many quotes].
