Mountain Goat Capture and Translocation

Current Project Status

This effort is a partnership between the National Park Service (NPS), the Washington Department of Fish & Wildlife (WDFW), and the USDA Forest Service (USFS) to re-establish and assist in connecting depleted populations of mountain goats in the Washington Cascades while also removing non-native goats from the Olympic Mountains. Mountain goats were introduced to the Olympic Mountains in the 1920s.

Under the approved Mountain Goat Management Plan/EIS, the first priority was to capture and translocate mountain goats to the Cascade Range where the populations are both native and depleted. One, 2-week capture and translocation operation occurred in 2020. In this fourth and final round of capture and translocation, a total of 50 mountain goats were captured and translocated to the northern Cascade Mountains which brought the overall total to 325 mountain goats released into the Cascade Mountains since the work began in 2018.

The plan calls for ceasing capture operations once they were no longer safe or efficient due to the remaining goats residing in terrain that is unsafe for capture operations. As predicted in the plan, the mountain goats were harder to catch safely as the operations progressed. By the fourth and final round of capture and translocation in August 2020, capture mortality increased from an average 5.2% after the first round to 9.1% and flight hours per live capture increased from 0.59 hours after the first round to 1.31 hours per goat. The remaining goats cannot be safely or efficiently captured. Overall, the project met the objectives of the capture and translocation phase of the Mountain Goat Management Plan/EIS. The total number of flight hours for capture (270 hours) was less than the estimated maximum hours, capture success was better than predicted, and WDFW released the estimated number of mountain goats into the Cascade Mountains thus achieving project goals there.

Olympic National Park recruited skilled volunteers to assist with the ground-based lethal removal of the remaining non-native mountain goats from the park in the fall of 2020. The ground-based lethal removal program using qualified volunteers ended in October 2020 with a total of 31 mountain goats culled from the population in the park. Ninety-nine highly skilled volunteers, organized in 20 groups of three to six volunteers per group, volunteered over 9000 hours while participating in the program. Ten mountain goats were removed in the first round, 18 were removed in the second round, and 3 were removed in the final round. A total of 412 mountain goats have now been removed from the Olympic Peninsula. Read the full news release.

2021 Project Dates and Camping Closures

The lethal removal phase of the plan will now switch to aerial operations for 2021. Two, 2-week aerial operations are planned for late July and late August/early September 2021.

The staging area for the helicopter will be located at Deer Park Campground. Loop A of Deer Park Campground will be closed to camping beginning at checkout time (11:00 am) on July 15 through August 1 (will open to camping for the night of August 2); and closed beginning at checkout time (11:00 am) on August 19 through September 2 (will open to camping for the night of 9/3). Loop B and C will remain open but campers should expect limited site availability as well as noise and activity beginning at 5:30 am. The area trails will remain open. (Map of Deer Park Closure)

The High Divide area of Seven Lakes Basin is closed to day use and overnight camping July 26 - July 29. Through hiking with a valid Wilderness Permit will be allowed after daily helicopter operations are complete (Map of Seven Lakes Basin closure area).

For the August operation, the area of Enchanted Valley from Pyrites Creek to Anderson Pass will be closed to overnight camping August 23 through August 29. (Map of Enchanted Valley area closure)

2019 Summary

Two, 2-week capture operations occured in 2019.

  • July 2019: 76 mountain goats were translocated.
  • August 2019: 101 mountain goats were translocated.

Since September 2018, a total of 275 mountain goats have been translocated from Olympic National Park and Olympic National Forest to the northern Cascade Mountains. An additional two-week capture and translocation period is planned for summer 2020.

2018 Operation Summary

The 2-week capture activities ended September 23 and the final translocation by the Washington Department of Fish & Wildlife took place on September 24. A total of 115 mountain goats were removed from the park. The Washington Department of Fish & Wildlife (WDFW) only translocated mountain goats from the park to the non-wilderness release sites within the North Cascades national forests during this first round.

Project Background

The National Park Service released its Record of Decision (ROD) for the Mountain Goat Management Plan/Final Environmental Impact Statement (EIS) in late June 2018 which outlines the effort to remove the 725 mountain goats estimated on the Olympic Peninsula at that time. Both the plan and the associated environmental impact statement were finalized after an extensive public review process which began in 2014. The United States Forest Service (USFS) signed its ROD in December 2018, which allowed the mountain goat capture and translocation activities to include USFS wilderness.

While mountain goats are not native to the Olympic Peninsula, they are native to the Cascade Mountains but exist in low numbers in many areas. Both the USFS and the Washington Department of Fish & Wildlife (WDFW) have long been interested in restoring mountain goats to these depleted areas.

The overall plan is to reach a zero population level of mountain goats in the park and adjacent Olympic National Forest lands through capture and translocation and then lethal removal. The top priority was capture and translocation of goats to the Cascade Range where the populations are both native and depleted. Once capture operations become impractical or hazardous due to steep terrain the remaining goats would be removed by lethal means.

The EIS, ROD, and other reference documents can be found on the NPS Planning Environment and Public Comment (PEPC) website at
