The sequoia National Park is one of the true treasures of Sierra Nevada, California. However, this corner of paradise is threatened every year by fires, which increasingly ravage huge areas of land. It is estimated that 20 percent of the park has been destroyed in the past three years by fire. U.S. firefighters have therefore initiated an action aimed at decreasing the risk of fire in the area, paradoxically using fire.
Prescribed fire is a technique used since the mid-twentieth century, whereby certain particularly flammable areas, such as dry shrubs for example, are set on fire to prevent any fire from spreading uncontrollably.
This technique is now widely used, but it takes tremendous preparation and experience to safely put it into practice. Impressive photos of the redwood forest, where the grandeur of the trees makes everything very striking and fascinating.
