KNP Complex Fire 100% contained

National Park Service officially declares the end of the KNP Complex Fire, measures it at 88,307 acres burned

SEQUOIA AND KINGS CANYON NATIONAL PARKS – News of the KNP Complex Fire has been on the back burner for a couple of months, but the National Park Service finally declared it 100% contained.

Last Thursday, Dec. 16, the KNP Complex Fire met its official end at 88,307 acres, most of which fall within Sequoia and Kings Canyon national parks. While the fire has not grown in recent weeks, it had continued to show activity in remote areas. Significant precipitation events across the Sierra Nevada prompted fire managers to declare the fire fully contained at this time.

“We hope that total containment on the KNP Complex is a comfort not only to local communities, but to people everywhere who care about the parks,” Leif Mathiesen, assistant fire management officer for Sequoia and Kings Canyon national parks, said. “While the onset of winter weather was the push we needed to reach full containment, it’s thanks to the incredible work of literally thousands of firefighting personnel that we were able to protect and save what we did. We’re very grateful to a lot of people.”

The KNP Complex was ignited by a large lightning event on the night of Sept. 9, 2021. Despite immediate and aggressive suppression efforts, the two fires that initially comprised the complex merged in the coming days and burned rapidly through a large area of Sequoia National Park, and into Kings Canyon National Park, Sequoia National Forest, Bureau of Land Management lands, and lands under tribal, state, county, and private jurisdiction. This fire evacuated many communities, closed public lands, and ultimately killed approximately 3-5% of the world’s population of mature giant sequoias.

Total containment means that the fire’s perimeter is considered secure, and no further growth is expected. This differs from the fire being declared “out.” Fire can become established in heavy fuels, such as large, downed trees, and may smolder there through multiple heavy snow and rain events, or even all winter, and become active again after the area dries out. Therefore, it may be a matter of months or longer before the KNP Complex is officially declared out.

Significant hazards from the KNP Complex remain in many areas of the parks, some of which will not be fully assessed or mitigated until at least the spring of 2022. National Park Service employees are working hard to reopen areas to public access as it is possible and responsible to do so.
