Roughly one-third of the nonnative mountain goats in Grand Teton National Park were killed by aerial gunners before Interior Secretary ordered a halt to the operation/NPS file

Airborne sharpshooters killed roughly one-third of the estimated 100 nonnative mountain goats in Grand Teton National Park before Interior Secretary David Bernhardt called off the hunt after Wyoming Gov. Mark Gordon complained that ground-based volunteer shooters weren't used.

Gordon, who fired off a stern letter to Grand Teton acting Superintendent Gopaul Noojibail about the aerial culling operation on Friday, called Bernhardt later in the evening. Bernhardt in turn ordered Noojibail to halt the operation.

On Tuesday the acting superintendent met with Gordon to discuss how best to protect the native Teton Range bighorn sheep herd from going extinct.

"It was a productive meeting and we greatly appreciate the governor’s time and interest," a Grand Teton release said Tuesday evening. "We value and respect the cooperation and perspective of our state partners and we are continuing conversations with them as the National Park Service implements actions to achieve our mutual goal of protecting the native Teton Range bighorn sheep herd from going extinct."

The culling operation stemmed from concern that mountain goats could transmit disease to the native bighorn sheep and compete for forage. According to park records, "It took roughly 40 years from (mountain goats') introduction in Idaho for mountain goats to establish a breeding population in the park."

The Wyoming Game and Fish Commission passed a resolution last month condemning the use of aerial gunning to remove mountain goats from the Targhee herd and urged Grand Teton to use skilled volunteers to kill the mountain goats. In a letter dated Jan. 28, 2019, the Wyoming Game and Fish Department formally recommended the park use skilled volunteers for mountain goat removal. Game and Fish Director Brian Nesvik made a third request to stop the plan on Friday, citing public disapproval.

However, the manner of removing the mountain goat population has been discussed between the state and the Park Service for more than a year, going back to the fall of 2018 when state officials were satisfied with the aerial culling, the Traveler has learned. Using volunteers to handle the task also was considered, and rejected, in the park's environmental assessment of the issue.

Because mountain goats are dispersed in backcountry areas, distant from road access, and seldom seen from park trails, there is little likelihood of successful expeditious control by volunteers on the ground. Thus, there would be little benefit in developing and managing a short-term ground-based skilled volunteer program to remove mountain goats. This alternative was dismissed because it is duplicative when compared to using skilled park staff and contractors to more effectively and efficiently remove the remaining mountain goats from the Teton Range. 

The environmental assessment also noted that "If lethal management is effective, it could be 5−30 years before goats disperse to the Teton Range again."

In Tuesday's release park staff said the aerial operation last Friday "was effective towards meeting the objective of removing nonnative mountain goats in the park. Thirty-six of the approximately 100 mountain goats were removed.  No additional aerial operations are planned."

Despite the conclusions of the environmental assessment, the release added that the park "is continuing to develop a skilled volunteer culling program that could be implemented as early as this fall. This culling program will utilize trained volunteers to remove non-native mountain goats via ground-based methods."

The release also noted the key differences between a culling program in a national park and traditional recreational hunting:   

o   Culling in a national park is done exclusively for conservation and stewardship purposes, while hunting is primarily for recreation or procuring food.   

o   Culling in a national park is conducted under controlled circumstances with the supervision of National Park Service personnel, while hunting is performed at the hunter’s discretion, subject to applicable licensing and laws. 

o   Volunteers may not keep any trophy when participating in a culling program in a national park. The meat may be distributed generally to volunteers, food banks, etc., after careful screening for public health considerations. 

o   Culling in a national park does not generate revenue and does not include fair chase.
