Are Sequoia trees and redwood trees the same thing?
Sequoias and giant redwoods are often referred to interchangeably, though they are two very different, though equally remarkable, species of tree. Both naturally occurring only in California, these two species share a distinctive cinnamon-colored bark and the proclivity for growing to overwhelming heights.

Will sequoias go extinct?
That's not to say the giant sequoia is about to go extinct. About 60,000 of the monarchs remain — though that's a big decrease from the 75,000 of a few years ago. Younger trees still abound, as well as sequoias that have been planted elsewhere.
How many sequoia trees were cut down?
Nearby wildfires last year killed an unprecedented 7,500 to 10,400 giant sequoias that are only native in about 70 groves scattered along the western side of the Sierra Nevada range. Losses now account for 13% to 19% of the 75,000 sequoias greater than 4 feet (1.2 meters) in diameter.

Today, the last giant sequoia on Earth live on land about the size of Cleveland (48,000 acres), in about 73 groves scattered along the western slopes of the Sierra Nevada. The northernmost sequoia grow in Placer County in Tahoe National Forest, and the southernmost groves live in Giant Sequoia National Monument.
Is the oldest sequoia tree still alive?
Muir Snag is believed to be the oldest redwood tree in the world. Muir Snag is estimated to be more than 3,500 years old, but is no longer living. Although the tree is dead, it is still standing in the Converse Basin of the Giant Sequoia National Monument in Sierra Nevada, California.
Did General Sherman Tree survive?
The General Sherman, the world's largest tree by volume, is just shy of 275 feet tall and is has a diameter of 36 feet at its base. The giant sequoia is estimated to be around 2,200 years old. The fire did not damage the famous tree and the Giant Forest where it stands was largely spared.
Why don t sequoias grow anywhere else?
Sequoias grow naturally along the western slope of the Sierra Nevada mountain range, between 5,000 and 7,000 feet (1,524 and 2,134 m) above sea level and far inland. That elevation provides the trees with dry mountain air necessary for their cones to open and release seeds.
Why do sequoia trees not burn?
Their thick, spongy bark insulates most trees from heat injury, and the branches of large sequoias grow high enough to avoid the flames of most fires.

Part of Hall of North American Forests. The giant sequoia offers a glance at more than 1,400 years of history. The tree from which the Museum's slice was taken stood over 300 feet tall before it was felled by loggers in California, in 1891. Today, it is illegal to cut down giant sequoias.

How high do sequoias grow?

Did the Sequoia fire do good?
Despite the destruction of the treasured behemoths, the fire did some good in other areas of the forest, Brigham said.
How long do sequoia cones stay in the ground?
The sequoia's cone-and-seed strategy evolved with fire. Sequoia cones retain their seeds – unlike other trees in their forest environs – in closed cones for perhaps 20 years. When fire burns through the forest the hot air dries out older cones. They open up and, within one to two weeks, begin to rain down their seeds loads onto fire-swept, bare soil.
How do sequoia trees survive fire?
Giant sequoias are adapted to periodic fire. Sequoia bark typically protects the trees against significant damage . At up to 18 inches (46 cm) thick and extremely fibrous, sequoia bark not only resists burning but also insulates the tree against fire's heat. Should fire penetrate the bark and scar the living tissue, new growth may heal the scar. However, giant sequoias experience many fires over their long lives, and may not keep up with healing over decades to centuries of fire scars. Thus, you will see blackened areas that extend from 1 to many feet up the height of older sequoias where fires scarred the tree many times.
How did giant sequoias die?

How have recent wildfires affected giant sequoia groves?
Two-thirds of all giant sequoia grove acreage across the Sierra Nevada has burned in wildfires between 2015 and 2020, compared to only one quarter in the preceding century. Thousands of large giant sequoias (those with trunks 4 feet in diameter or larger) are estimated to have been killed in just four recent wildfires (Figure 1), most of those in the 2020 Castle Fire. Based on aerial surveys from a helicopter, fire severity estimates, and sequoia grove maps, 10 to 14 percent of the world's large sequoias are estimated to have died in the Castle Fire, or 7,500-10,600 trees (Stephenson and Brigham, in press). Upcoming fieldwork will help scientists determine more precise giant sequoia mortality estimates.
How many giant sequoias died in the 2016 drought?
During and after the 2012-2016 hotter drought, USGS scientists and park managers in Sequoia and Kings Canyon National Parks documented a total of 33 giant sequoias that died standing in several different sequoia groves. All of these trees had experienced recent fire and many had some basal fire scarring. Most of them grew in very wet areas, and a native bark beetle in the Phloeosinus genus appears to have killed them. Beetle kill of giant sequoias is a newly reported phenomenon, believed to be the result of drought-related impacts.
How do giant sequoias die?
Prior to the recent severe drought, research about giant sequoia mortality suggested that large sequoias typically died by falling or, occasionally, having extensive crown scorch from fire. Death while standing, unrelated to crown scorch, was almost never observed by scientists who had spent decades working in the Sierra Nevada. And while mature giant sequoias did die from fire impacts, that was a relatively rare event, typically the result of many accumulated injuries over their long lives.
What is the impact of the hotter drought on the Sierra Nevada?
In hotter droughts, unusually high temperatures worsen the effects of low precipitation, resulting in greater water loss from trees and lower water availability. This is an emerging climate change threat to forests. This article provides a brief overview of the following impacts associated with the hotter drought:
What trees did the 2012-2016 drought kill?
The 2012-2016 drought killed many non-sequoia species of trees (pines, incense-cedars, firs), helping create an increase in existing fuels. While much of the tree mortality was in lower elevation pine forests, the drought also caused elevated mortality (and increased fuels) at mid-elevations where giant sequoias grow.
What causes fires to burn at night?
Extreme fire weather – In some cases, very low relative humidity and higher than average temperatures resulted in unusually low fuel moistures (amount of moisture in live trees as well as sticks and logs) enabling fire to burn actively day and night. Extreme fire behavior, poor air quality from smoke, and remote, rugged terrain hampered fire control efforts in some areas.
Why are giant sequoias more resistant to fire?
Larger giant sequoias are more resistant to fire damage, due to their thick protective layer of nonresinous bark and elevated crowns. However, repeated fires over many centuries may penetrate the bark and destroy the vascular cambium.

It is neither the tallest extant species of tree (that distinction belongs to the coast redwood ), nor is it the widest (that distinction belongs to the baobab tree or Montezuma cypresses ), ...
Why do sequoia trees die?
The most common cause of death in mature giant sequoias is toppling, due to weakening of the roots and lower trunk by fire and decay. The extreme weight of the trees coupled with their shallow root systems contributes to this weakening. Other causative factors include wind, water-softened soils, undercutting by streams, and heavy snow loads in the crowns.
