Iconic forests that stretch across Kings Canyon, Sequoia and Yosemite national parks are beginning to fray at the edges as the warming climate is creating unsuitable growing conditions, according to a study led by Stanford University researchers.

Threats to visitors and park infrastructure posed by 12,000-15,000 "hazard trees" burned during the massive KNP Complex fire of 2021 at Kings Canyon and Sequoia national parks but still standing has the National Park Service formulating a plan to deal with them. The agency's preference is to remove tree hazards along roadways and the parks' developed areas within the fire's burn perimeter and then treat fallen debris around infrastructure and within up to 80 feet from the edge of roadways.

The long holiday weekend might not be the best time to visit Sequoia or Kings Canyon national parks, as recent storms have damaged roads and spawned mudslides, and more harsh weather is in the forecast.

Two congressmen from California are pushing to see 1.4 million acres that lie between Yosemite and Kings Canyon national parks moved from the U.S. Forest Service and U.S. Bureau of Land Management to the National Park Service and recognized as the Range of Light National Monument.
