Sequoiadendron giganteum (giant sequoia; also known as giant redwood, Sierra redwood, Sierran redwood, Wellingtonia or simply big tree—a nickname also used by John Muir) is the sole living species in the genus Sequoiadendron, and one of three species of coniferous trees known as redwoods, classified in the family Cupressaceae in the subfamily ...
What is the habitat of the giant sequoia tree?
Natural habitat.—The giant sequoia is found growing singly or in groups scattered for a distance of 250 miles along the western slopes of the Sierra Nevada in central California at elevations of 4,000 to 8,000 feet.
What is it like to be under a sequoia tree?
A forest with giant sequoias is a feast for the senses. The giant sequoias’ red/orange bark is distinct among the grey and brown bark of other trees. And if you stand beneath one of these giants, you can gaze all the way up its tall trunk and through its high branches to see sky above. The treetop is often hidden above the highest branches.
How many species of Sequoia are there?
The only extant species of the genus is Sequoia sempervirens in the Northern California coastal forests ecoregion of Northern California and Southwestern Oregon in the United States. The two other genera, Sequoiadendron and Metasequoia, in the subfamily Sequoioideae are closely related to Sequoia. It includes the tallest trees in the world.

Are sequoias redwoods pine trees?
And to clear a common misconception up front, a sequoia is not a pine tree at all! Sequoiadendron giganteum is also called Sierra redwood, a coniferous evergreen tree of the cypress family (Cupressaceae), the largest of all trees in bulk and the most massive living things by volume.
Does a sequoia have pine cones?
A large sequoia tree can have several thousand pinecones at a time. Although giant sequoia trees are among the largest trees in the world, their pinecones are comparatively small, usually only 2 inches or so.
Are redwood trees related to pine trees?
Members of the pine family (pine, spruce, fir and cedar) have cones with overlapping scales. Members of the cypress family (cypress, juniper and redwoods) have scales which are completely fused.
What kind of wood is a sequoia?
softwoodIt is a light weight softwood with good weight to strength ratio. Because of its weather resistance it is commonly used for decks and outdoor furniture. It can also be used for veneer, construction lumber, posts, beams, turnings, and in musical instruments. It can range from straight grain, to curly, wavy, or burl.
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.
Why are sequoia trees so special?
Giant sequoias are one of the world's hardiest trees. Their thick bark makes them flame resistant, as well as resistant to fungal rot and wood-boring beetles.
Is redwood and pine the same?
Redwood is typically from a pine tree and is grown in colder climates. Places like Norway, Denmark, and Finland. Now, pine grows far slower than spruce, and this means that its growth rings are a lot tighter together, making the timber very dense. This results in redwood boards being far more sturdy once cut.
Which is stronger pine or redwood?
Redwood is harder than sugar Pine and Yellow Pine, but softer than yellow Pine. Both Pine and Redwood belong to the softwood family.
How can you tell redwood from pine?
Color and Growth California and giant redwoods as well as loblollies and short-leaf pines feature distinctive cinnamon-colored bark. Loblollies feature dark green needles and short-leaf pines bear needles of bluish-green. California redwoods also have dark green needles, but some varieties feature a blue-green color.
Is sequoia wood good for anything?
The exceptional quality of the wood, along with its attractive colour, make it a sought-after material for the timber industry. Many high-end pieces of furniture are created using sequoia; its strength and durability establish the sequoia as the perfect option for crafting windows, doors and other woodwork projects.
Are redwoods and sequoias 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.
Which is older sequoia or redwood?
The oldest coastal redwood is 2,520 years old and the oldest giant sequoia is about 3,200 years old, Burns said.
Do redwoods have pine cones?
Redwood trees flower during the wet and rainy months of December and January. They produce cones that mature the next fall. Redwood cones are about an inch long and they produce tiny seeds, about the same size as a tomato seed. While each tree can produce 100,000 seeds annually, the germination rate is very low.
Can you take sequoia pine cones?
It is technically against park rules to take pinecones out of the park because they are part of its ecosystem.
How do you tell if a tree is a sequoia?
Giant Sequoia – The namesake of the forest and the largest tree on Earth, the giant sequoia is an impressive tree. It does not have a very large cone. It is about the size and shape of a chicken egg. Its needles are similar to a incense cedar but are rounded and prickly to the touch.
What tree has the largest pine cones?
Coulter pinesThe Heavyweight: Coulter Pine (Pinus coulteri) Coulter pines, native to the mountains of southern California (U.S.) and Baja California (Mexico), produce the most-massive cones of any pine species. Known colloquially as “widow-makers,” those giant pinecones can weigh up to 5 kg (11 pounds)!
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.
When Fire Is Excluded – What Happens?
During the century from the late 1800s until the late 1900s, fire was rare in many giant sequoia groves due to land use changes and many decades of fire suppression. What were the consequences for giant sequoias? As tree ring studies revealed the fire history of sequoia groves, they also were used to age sequoias to better understand the population of giant sequoias in three groves — Giant Forest and Atwell Groves in Sequoia National Park and Mariposa Grove in Yosemite. Were there enough young trees to replace the older ones in future years?
What is prescribed burn in Sequoia National Park?
A prescribed burn in Giant Forest, Sequoia National Park, 2011. Prescribed fire is used by managers to restore fire in giant sequoia groves. Fire kills some of small or medium-sized trees, reducing wildfire hazard, and creating sunlit gaps in the forest where young trees can grow.
How many giant sequoias were burned in the fire?
While assessment of fire impacts is still underway, we know that the fire burned 12 giant sequoia groves in these parks, with differing levels of fire severity depending on their fire history and location. Groves on warmer and drier south-facing slopes, and with no recent fire, sustained extensive mortality of monarch giant sequoias.
Why do sequoias not grow?
Before the arrival of European settlers in the mid-1800s, successful establishment of mature sequoias depended on fires intense enough to kill the tree canopy in small areas, allowing enough light for young sequoias to grow and thrive. Giant sequoias are a pioneer species—they are among the first to take root after a disturbance occurs. Another consequence of the lack of periodic fire is that burnable material, or fuel, accumulates. When trees and shrubs become more dense and logs, sticks, and fallen leaves or needles build up on the ground, higher severity fire is more likely to occur. When fire burns more often, it thins out younger trees, and reduces fuel on the ground.
Why are fires important to sequoias?
The importance of fire to giant sequoias cannot be overstated. Other than the change of seasons, fire is the most recurrent and critical process in determining the life history of this species. Tree-ring records from giant sequoias show that frequent surface fires were the typical pattern of fire occurrence over the past 2,000 years. But this pattern changed after about 1860, when fire frequency declined sharply. This decline in regional fire was probably a result of intensive sheep grazing that began about this time (reducing live and dead vegetation that carries ground fire beneath the trees) and a decrease in fires set by Native Americans, followed by fire suppression by government agencies.
How many sequoias were destroyed by fire?
However, in the approximately 13 percent of the grove area in the park that burned at high severity, we currently estimate that hundreds of large sequoias (over four feet, or 1.2 meters, in diameter) were destroyed by fire.
How long do conifer trees live?
When trees can live for 2,000 to 3,000 years, it's important to understand the longer term history of fire in these forests, and how that history relates to climate. Many conifer tree species such as giant sequoias and pines can operate as "recorders" of fire events.

What is a Sequoia?
Condylocarpus Salisb. ex Lamb. Sequoia is a genus of redwood coniferous trees in the subfamily Sequoioideae of the family Cupressaceae. The only extant species of the genus is Sequoia sempervirens in the Northern California coastal forests ecoregion of Northern California and Southwestern Oregon in the United States.
What caused Sequoia to become extinct?
Continued cooling in the Pliocene meant that Sequoia, which is extremely intolerant to frost due to the high water content of its tissues, also became locally extinct in response to the extreme cooling of Europe and Asia In western North America it continued to move south through coastal Oregon and California, surviving due to the abundant rainfall and mild seasons. The Sierra Nevada orogeny further isolated Sequoia because the snowy mountain peaks prevented eastward expansion. The Pleistocene and Holocene distributions are likely nearly identical to the modern S. sempervirens distributions.
Where did Sequoia Jeholensis originate?
Sequoia jeholensis is the oldest recorded member of the genus Sequoia (Along with Sequoia portlandica, but this last is a nomen dubium) , know from the Jiufotang Formation (Lower Cretaceous) and the Jiulongshan Formation (Middle Jurassic) of China. By the late Cretaceous the ancestral sequoias were established in Europe, parts of China, and western North America. Comparisons among fossils and modern organisms suggest that by this period Sequoia ancestors had already evolved a greater tracheid diameter that allowed it to reach the great heights characteristic of the modern Sequoia sempervirens (coast redwood) and Sequoiadendron giganteum (giant sequoia).
When was the name Sequoia first published?
The name Sequoia was first published as a genus name by the Austrian botanist Stephan Endlicher in 1847. However, he left no specific reasons for choosing that name, and there is no record of anyone else speaking to him about its origin.
Why is the Sequoyan genus named Sequoyan?
The most common modern guess is that Endlicher, a published linguist, sinologist, philologist, as well as a systematic botanist, named the genus in honor of Sequoyah, the inventor of the Cherokee writing system, now known as Sequoyan. Beginning in the 1860s, it was suggested that the name is instead a derivation from the Latin word for "sequence", since the species was thought to be a follower or remnant of massive ancient, extinct species, and thus the next in a sequence.
Did Endlicher have knowledge of Sequoia sempervirens?
However, in a 2012 article, author Gary Lowe argues that Endlicher would not have had the knowledge to conceive of Sequoia sempervirens as the successor to a fossil sequence, and that he more likely saw it, within the framework of his taxonomic arrangements, as completing a morphological sequence of species in regards to the number of seeds per cone scale.

How long does it take for a giant sequoia to grow?
The giant sequoia regenerates by seed. The seed cones are 4–7 cm ( 1. +. 1⁄2 –3 in) long and mature in 18–20 months, though they typically remain green and closed for as long as 20 years. Each cone has 30–50 spirally arranged scales, with several seeds on each scale, giving an average of 230 seeds per cone.
How tall are sequoia trees?
Giant sequoia specimens are the most massive individual trees in the world. They grow to an average height of 50–85 m (164–279 ft) with trunk diameters ranging from 6–8 m (20–26 ft). Record trees have been measured at 94.8 m (311 ft) tall.
Why is Sequoia named Sequoia?
Endlicher is actually responsible for the name. A linguist and botanist, Endlicher corresponded with experts in the Cherokee language including Sequoyah, whom he admired. He also realized that coincidentally the genus could be described in Latin as sequi (meaning to follow) because the number of seeds per cone in the newly classified genus aligned in mathematical sequence with the other four genera in the suborder. Endlicher thus coined the name "Sequoia" as both a description of the tree's genus and an honor to the indigenous man he admired.
How many giant sequoias have died?

What is the post mortem site of another monarch that died in this way?
The post-mortem site of another monarch that died in this way stretches along the forest floor a short walk from Lazarus. The tree, unnamed, had been felled and cut into chunks to protect tourists passing on a nearby road. At what would have been the top, the bark exhibits the telltale cause of death: the elegant spirals and grooves of beetle galleries, formed where the insects are thought to have entered and slowly killed the weakened tree.
