Are Sequoia trees and redwood trees the same thing?
Sequoias and redwoods are closely related. The primary difference between sequoias and redwoods is their habitat. Redwoods live near the coast, while sequoias live in subalpine regions of California. Redwoods are the tallest trees in the world. Sequoias are the biggest, if measured by circumference and volume.

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 did giant sequoias die?

What is the largest tree in the world?
A forest with giant sequoias, the largest trees in the world, 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.
What is the role of fire in the Sequoia?
Fire plays a crucial role in the giant sequoia ecosystem. Toward summer's end in the dry season forest conditions favor fire, and lightning storms are not uncommon in the mountains. Fire scars in tree rings dating back 2,000 years show that widespread fires occurred naturally at intervals ranging from 6 to 35 years in these forests.
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.
How many giant sequoias are there in California?
There are 65–75 groves of giant sequoias in the Sierra Nevada, depending upon the criteria used to define a grove.

Acute Foliage Dieback
Acute foliage dieback occurred in many giant sequoias in Sequoia and Kings Canyon National Parks as a short-term response to the drought. Dieback was most pronounced in 2014, the most severe drought year in the park’s 122-year record. Amounts of dieback on individual trees ranged from none to >75%.
Summary
Prior to 2014, scientists recorded only subtle, long-term changes in forest health. During and after the drought, they observed large, abrupt, and novel changes to forests, including in numerous giant sequoia groves.
Responding to Change
Responses to these sudden changes will take coordination across organizations managing giant sequoias and with scientists, and non-governmental organizations. The National Park Service is working with partners to create:
What is the chemical compound that protects a giant Sequoia tree from fungus?
Coniferous trees (such as the Giant Sequoia) are known for possessing high levels of Tannin. By the way, Tannin is an insoluble chemical compound that is resistant to all forms of diseases that can affect trees. Tannin guards the Giant Sequoia tree against fungus and protects it against insect attacks. Fact 17.

Overview
The giant sequoia (Sequoiadendron giganteum) is the world's most massive tree, and arguably the largest living organism on Earth. 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), nor is it the longest-lived (that distinction belongs to the Great Basin bristlecone pine). However, with a height of 87 meters (286 ft) or more, a circumference of 34 …
Distribution
Giant sequoias occur naturally in only one place on Earth—the western slope of the Sierra Nevada mountain range in California, on moist, unglaciated ridges and valleys at an altitude of 1,500 to 2,400 meters (5,000 to 8,000 ft) above mean sea level. There are 65–75 groves of giant sequoias in the Sierra Nevada, depending upon the criteria used to define a grove. The northernmost of these groves is Placer County Grove in the Tahoe National Forest, Placer Count…
Fire limits growth
Giant sequoias are in many ways adapted to forest fires. Their bark is unusually fire resistant, and their cones will normally open immediately after a fire. However, fire is also the most serious damaging agent of giant sequoias. Seedlings and saplings are highly susceptible to death or serious injury by 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 ov…
Tree measurement
As with other trees, measurement of giant sequoias is conducted using established dendrometric techniques. The most frequent measurements acquired in the field include the height of the tree, the horizontal dimension of its canopy, and its diameter at breast height (DBH). These measurements are then subjected to tree allometry, which employs certain mathematical and statistical principles to estimate the amount of timber volume in a tree.
Calculating the volume of a standing tree is the practical equivalent of calculating the volume of an irregular cone, …

indicates a giant sequoia that sustained heavy fire damage after its most recent volume estimate.
• The trees Named "Franklin", "Column", "Monroe", "Hamilton" and "Adams" were named by Wendell Flint and others. These five are now included on the official map of Giant Forest, where they are all situated.
