RANGE RIDING

This month cattle started moving into higher country and onto a few Forest Service Permits, making for some longer rides. Range riders are continuing to monitor six herds of cattle and track wildlife primarily in areas used by livestock.

Riders have observed that in herds NOT contained by electric fence, cow/calf pairs are naturally keeping themselves in multiple small groups and responding to potential threats very quickly and seemingly effectively (cows quickly mother up with their calves). Riders have also observed that in pastures with rugged terrain and thick ground cover, cattle tend to scatter more with only a few individuals near each other at any given time.  These cattle also tend to flee when threatened. Riders are making an effort to document different cattle behavior in response to a predation threat and will continue to do so throughout the season.

CARCASSES

Riders have found 3 elk calf kills and 1 adult elk kill in areas also used by livestock. No livestock have died (that riders know of) this month and no carcasses of domestic animals or wildlife have been removed. 


TRACKING

By mid June, riders noted that elk were coming back together in small herds (8-14 adults) and observed 2017 calves in the herds on two occasions. There have been some elk either co-mingled with cattle or less than 400 yards from cattle on a daily basis. 

Wolf presence during the month of June, through observations and tracks, has been lower this year than it has been in the past five years. However based on GPS and VHF data from the collared wolves in this pack, it appears that wolves are frequently traveling through and around the Basin and often moving through pastures being used by cattle. Therefore, we are concluding that the wolves are still using the Basin similar to how they have in the past, but they are becoming more wary of humans (thus having less encounters with humans). Documentation of wolves by riders on trail cameras is high and supports the thought that wolves are still actively using the Basin despite fewer visual observations. 

Near the end of June, grizzly bear activity began to increase after a fairly slow, but characteristic early June. One sow with two cubs of the year has been documented. In addition, the sow responsible for a depredation on a two-year-old steer last year has been seen out and about with three cubs of the year. This bear is still wearing the GPS collar that was put on her in 2016. Several individual bears have been observed and tracked, as well. A single adult grizzly has been documented foraging in a pasture and near a herd of cow/calf pairs. Both the bear and the cattle appeared unbothered by each other over the course of multiple days.
