General Sherman, the Giant Sequoia above, is the largest living single organism on earth. Over half of the largest trees on earth are in this park and in neighboring Sequoia National Monument, Sequoia National Forest and Kings Canyon. This park is my favorite for giant trees. For millions of years, these magnificent trees thrived here, near the southern end of the Sierra Nevada—‘jagged, snowy’—mountains. The taller, thinner coastal redwoods mainly live closer to the Pacific where cool ocean breezes bring fog, protecting them.

But in a small fraction of one Giant Sequoia’s 3,000 year lifespan, humans have burned so much carbon into the atmosphere that the mountains here no longer hold snow all year, serving the immovable trees an eviction notice. Just in 2020-2021, between 13% and 19% of the world’s Giant Sequoias were burned to death in consecutive huge wildfires here. These trees evolved to survive fire, and, until recently, mature Giant Sequoias survived wildfires. The Climate Crisis has changed that, putting this species at risk of extinction in our lifetimes.

Many of the groves and much park wilderness are currently unreachable, due to post-fire erosion washing out roads, bridges and trails. Finding sections of the park unmarred by burn scars is challenging. The trees here are magnificent, but I recommend visiting Redwood to find solace. While most of our Giant Sequoias still live here for the time being, please don’t burn gas to get here. The last giant forests the loggers failed to destroy with sawmills, we are destroying with our cars and airplanes. By choosing to burn carbon, we are destroying the ecosystem these magnificent trees needed to live naturally for thousands of years. It would be too sad to visit only to say goodbye.
