Jackson Hole Pronghorn fawn recruitment is off the chart this year at an index of 80 fawns per 100 does, twice the normal birthing pattern for these parts..........So here is a case of every pre columbian carnivore(Griz and Black Bears, Wolves, Coyotes, Pumas, Golden and Bald Eagles) being present in the Jackson Hole bioregion and the Pronghorns are thriving regardless..............Weather, Weather, Weather is my guess for the surge of our speediest herbivore-----warm winter, an earlier spring green-up and "presto"--more Elk on the range-------Please enter in and provide your insights to what I am missing in describing this phenomena

JACKSON, Wyo. (AP) — State biologists have counted near-record numbers of summering pronghorn antelope in Jackson Hole this year. In addition, they have found the highest fawn ratios since modern record-keeping started in Jackson Hole.

The Wyoming Game and Fish Department survey is used to determine hunting quotas and seasons for the following year. It's a trend survey and is not considered a census count of the population.
Game and Fish wildlife biologist Doug Brimeyer says he counted some 400 pronghorn in the area, including about 260 in Grand Teton National Park.

Brimeyer tells the Jackson Hole News  Guide  that he is seeing about 80 fawns per 100 does this year. That's well above the usual 40 to 60 seen in Jackson Hole.
