A intense forest fire, caused by a lightning strike on August 24, has severely impacted the Sierra National Forest (SNF) and its giant sequoias in the state of California, United States.
The fire, named Garnet, is active in Fresno County and has reached critical areas of the McKinley Forest, directly affecting a group of giant sequoias, some of which are up to 3,000 years old.
Specialized Operation to Protect Ancient Trees
Wildland firefighters with climbing experience are working in the treetops to contain the flames.
To protect these vegetal giants, emergency teams have deployed tree-climbing specialized firefighters who are fighting the flames burning in the sequoias’ canopies. According to Jay Tracy, spokesperson for the operation, measures such as the following have been implemented:
- Sprinkler lines to increase soil moisture
- Trunk wrapping with fire-resistant aluminum foil blankets
- Raking of flammable material at the base of the trees
- Constant patrolling to detect hot spots
Unique Characteristics of Sequoias and Their Relationship with Fire
Low-intensity fires are part of the natural cycle, but the current one exceeds tolerable levels.
Giant sequoias naturally grow in a 420-kilometer strip on the western slopes of the Sierra Nevada and can reach over 90 meters in height. They are the largest trees in the world by volume and are related to the redwood tree, the tallest tree on the planet.
Although these species rely on controlled fires to open their cones and spread seeds, the Garnet fire presents an intensity higher than usual, putting their survival and that of the surrounding ecosystem at risk.
Concern about the fire affecting the giant sequoias
Territorial Impact and Fire Status
Over 220 km² destroyed in a popular area for camping and hiking.
As of Tuesday, the fire had consumed 220 square kilometers of grass, chaparral, and wood in a remote region located 97 kilometers east of Fresno, known for its recreational activities.
The fire was contained at only 14%, keeping forest authorities on alert.
The Sierra National Forest: Biodiversity and Natural Heritage
It is a protected area of 540,000 hectares managed by the U.S. Forest Service.
The Sierra National Forest is a federal reserve covering 540,000 hectares in Fresno, Madera, and Mariposa counties. Its altitude ranges from 274 to 4,380 meters, offering a diverse landscape and panoramic views.
It is a key destination for hiking, camping, and nature observation, and it harbors ecologically valuable natural resources.
