The world’s largest tree, by volume, is a giant sequoia (Sequoiadendron giganteum) known as General Sherman. General Sherman is located in Sequoia National Park in California’s Sierra Nevada mountains. With a height of 83.8 meters (275 ft) and a volume of 1,487 cubic meters (52,500 cubic ft), General Sherman is not only the largest giant sequoia but also the largest individual tree in the world.
General Sherman’s exact location is near the northwestern side of the Giant Forest within Sequoia National Park. The tree can be accessed via a short hiking trail, making it a popular destination for visitors to the park. Seeing the massive General Sherman in person helps provide perspective on just how enormous these giant sequoia trees truly are.
Background on Giant Sequoias
Giant sequoias are a threatened tree species native only to the western slopes of the Sierra Nevada mountain range in California. They are the world’s largest trees in terms of volume and can live for over 3,000 years, making them some of the longest-lived organisms on Earth.
Giant sequoias grow naturally in groves scattered along a narrow 420 kilometer (260 mile) belt on the western slopes of the Sierra Nevada. These groves generally occur between 1,400–2,100 meters (4,600–6,900 ft) in elevation. The cool, wet climate of these high-mountain habitats provides the right conditions for giant sequoias to thrive.
There are a total of 75 giant sequoia groves that contain large numbers of the trees. Though once more widespread, logging and land clearing during the late 1800s destroyed many former giant sequoia groves outside of protected National Park areas. Today’s remaining groves are largely confined to protected areas in National Parks, National Monuments, and National Forests.
History of General Sherman
General Sherman is estimated to be around 2,300-2,700 years old. The first recorded documentation of General Sherman dates back to 1879, when naturalist James Wolverton discovered the massive tree and named it after famous Civil War general William Tecumseh Sherman.
For thousands of years before its discovery, General Sherman stood majestically in the Giant Forest of Sequoia National Park, slowly growing into the giant we know today. Its origins trace back to the early BC era over two millennia ago.
When General Sherman was first documented by Wolverton in 1879, it already had a height of 84 meters (275 ft), meaning the tree was already about 2,000 years old. In that year, the base diameter measured 11 meters (36 ft).
Over the past 140+ years since its discovery, General Sherman has continued growing. Though giant sequoias put on height growth slowly after their first few hundred years, they continue increasing trunk diameter and volume for many centuries.
Measuring General Sherman
Given its status as the largest tree in the world, General Sherman has been carefully measured over the decades by researchers and scientists. The tree’s volume and dimensions can fluctuate slightly over time, but have been consistently verified through measurements.
Some key stats on General Sherman’s size:
– Height: 83.8 meters (275 ft)
– Base diameter: 11.1 meters (36.5 ft)
– Largest branch diameter: 2.44 meters (8 ft)
– Estimated bole volume: 1,487 cubic meters (52,500 cubic ft)
The tree’s massive trunk tapers up significantly from the wide base, giving it a very large volume despite not being abnormally tall for a giant sequoia. General Sherman’s crown spreads outward over half an acre.
Researchers periodically carry out measurements of General Sherman to track any changes in size. The most recent detailed measurement was done in 2015. Sophisticated laser scanning technology was used to model the tree’s structure and volume in 3D.
General Sherman Tree Trail
|Length||0.8 miles round trip|
|Time to Complete||30-45 minutes|
Visiting General Sherman is easy via the designated General Sherman Tree Trail. This paved trail begins at the Generals Highway in Giant Forest and is only 0.8 miles round trip. The hike is wheelchair accessible and suitable for visitors of all ages and abilities.
The well-maintained trail passes through the forest before reaching the tree. You first see the massive base of General Sherman come into view. As you get closer, you truly appreciate the enormity of this giant sequoia. Informational signs tell about the tree’s history and dimensions.
A wide paved area surrounds General Sherman to accommodate crowds of visitors. While busy at times, seeing General Sherman makes for an unforgettable experience. Plan to spend 30-45 minutes walking the trail at a leisurely pace and appreciating the tree.
Other Notable Giant Sequoias
While General Sherman is the undisputed largest, there are many other giant sequoias that can lay claim to their own unique distinctions:
General Grant Tree: The world’s second largest tree by volume, with a trunk measuring over 100 ft (30 m) in circumference. It is the centerpiece tree of Grant Grove in Kings Canyon NP.
President Tree: At over 73 meters (240 ft), this is among the tallest known giant sequoias. It grows in the Redwood Mountain Grove of Kings Canyon NP.
Boole Tree: With a basal diameter of over 17 meters (56 ft), this sequoia has the widest base of any known giant sequoia specimen. It is located in the Converse Basin Grove.
Chicago Stump: The remains of what was once the second largest tree but was cut down in 1893 for exhibition at the World’s Columbian Exposition.
Washington Tree: Prior to General Sherman’s discovery, this was considered the largest giant sequoia. It has a volume of 1,380 cubic meters (48,750 cu ft).
Threats to Giant Sequoias
Though protected today, giant sequoias face several threats to their long-term survival:
– Climate change: Hotter droughts stress and weaken trees, making them vulnerable to diseases and pests. Wildfires are also becoming more severe.
– Fragmented habitat: Remaining groves are isolated islands surrounded by development. This makes healthy regeneration difficult.
– Recreation impacts: Heavy visitation compacts soil and roots. Soil erosion in groves also threatens the trees.
– Fire suppression: Controlled fires are needed to open cones and clear undergrowth. Lack of good fires allows denser growth.
To protect General Sherman and other giant sequoias into the future, sustainable management practices are needed. This includes prescribed burning, forest restoration, visitor management, and grove connectivity projects. Proper funding to National Parks and Monuments is also essential for conservation.
General Sherman remains a living testament to the grandeur of giant sequoias, the longevity of life, and the majesty of nature. This iconic giant has rightly earned its status as the largest tree in the world. Visiting General Sherman is a humbling experience that puts one’s existence into proper perspective. With the right stewardship, this colossal sequoia can stand tall for thousands of years to come.
