No activity has been reported since September 29, when gather ops commenced at Coyote Lake.

Owyhee Roundup Announced
The incident will begin on or about October 11, according to the new release.
It was on the schedule dated August 2 but was dropped from the current schedule, dated August 30.
Helicopters will push the horses into the traps and the operation will be open to public observation. Five HMAs are involved.
The capture goal is 947 and the removal goal is 615. Mares returned to the Complex will be treated with PZP.
The Complex covers about one million acres and has an AML of 999, as shown in Table 1 of the Final EA for resource enforcement actions therein. The stocking rate allowed by plan is one wild horse per thousand acres, in line with the target rate across all HMAs.
The pre-gather population was estimated to be 1,188.
The Complex intersects six grazing allotments, listed in Table 5 of the EA. Figure 13 shows the arrangement. The image above is from the Western Watersheds map.
Captured animals will be taken to the Sutherland off-range corrals in Utah.
Gather stats and daily reports will be posted to this page.
The EA was posted with other project documents in ePlanning.
Western Horse Watchers does not see the wisdom of mobilizing a contractor in an area that is only 20% above AML and almost certainly below the True AML.

The Rock Springs allotment covers about two million acres of public and private lands in the Wyoming checkerboard and is administered by the Rock Springs Field Office.

Draft EA for Spring Mountains Complex Out for Review
Yesterday marked the beginning of a 30-day comment period on a new environmental assessment for wild horse and burro management in the Spring Mountains Complex, west of Las Vegas, NV.
The Complex includes lands managed by the USFS and BLM, and consists of three Joint Management Areas, according to a BLM news release. Map 1 in Appendix A of the EA shows the arrangement.
The Proposed Action would implement a Herd Management Area Plan that affirms the AMLs for the Red Rock and Spring Mountains / Wheeler Pass JMAs and increases the AML for the Johnnie JMA. The current AMLs are shown in Table 1 of the EA, with the proposed AMLs in Table 3.
The Proposed Action features removal of excess animals, fertility control vaccines, surgical sterilization and sex ratio skewing.
The Complex consists of 784,326 acres of public lands, with 164,856 acres (21%) managed by the Forest Service and 619,470 acres (79%) controlled by the BLM.
The three JMAs, Red Rock, Johnnie and Spring Mountains / Wheeler Pass, cover 187,639 acres, 216,874 acres and 379,813 acres, respectively.

The combined AMLs under the Proposed Action are 127 horses and 192 burros, with a total forage demand of 2,676 AUMs per year. Table 3 yields 2,670 AUMs per year.
The proposed AMLs are equivalent to 223 wild horses, for an aimed-at stocking rate of 0.3 wild horses per thousand acres. The average rate across all HMAs is one wild horse per thousand acres.
The Complex includes one grazing allotment, Wheeler Wash, according to the Western Watersheds map, with no active AUMs.
Comments will be accepted until October 29.
The EA was posted with other project documents at the Forest Service NEPA site.

Any Livestock Grazing Near Little Bookcliffs?
Grazing is not allowed inside the HMA but it’s surrounded by allotments.
Would that explain why the advocates are trying to keep the herd in check with PZP?

Map Shows Grazing Allotments, HMAs and WHTs
Western Watersheds Project released an interactive map last week that shows areas identified for livestock grazing relative to areas reserved for wild horses and burros.
No more guessing if an HMA or WHT is subject to permitted grazing!
See if you can find the Rock Springs HMAs in southwest Wyoming. Table 8 in the Final EA for resource enforcement actions shows the HMAs and the allotments that overlap them. Zoom in to see the boundaries.
One problem is the pop-up box that appears when you click on an allotment. It may it hide the area you’re trying to view. You can’t drag it out of the way so the workaround is to click on the eastern side of the parcel.
The map shows the BLM Field Offices so you can get additional information about the allotments from RAS. The map also shows the USFS Ranger Districts but as of today, Western Horse Watchers has not found a similar reporting tool for their allotments.
