Giant sequoia trees scorched by the 2020 SQF Complex wildfire stand in Sequoia National Forest in California.

Historically, giant sequoia trees have coexisted with wildfires for thousands of years, as their thick bark normally insulates the inner wood from heat.

According to the Forest Service, wildfires have destroyed nearly 20 percent of all giant sequoia trees in the past two years amidst ongoing drought, increased temperatures and fuel (vegetation) build-up.

The massive trees can live for over 3,000 years and average between 180 to 250 feet in height.

The Forest Service has begun emergency action to reduce fuels near unburned giant sequoia groves in the national forest to reduce wildfire risks.
