Top 10 Gigantic Ancient Trees in the World

Red Creek Fir is known as a large Douglas fir tree (Pseudotsuga menziesii) located in the San Juan Valley on Vancouver Island, British Columbia, Canada. By mass, this is the largest known Douglas fir tree on Earth. The Red Creek Fir tree was seeded around 1000 BCE. It thrives due to its location on the cool southern slope of the San Juan Valley and is less than 0.5 km from the San Juan River.

Despite various efforts by the Ancient Forest Alliance, Red Creek Fir still lacks official government protection beyond being placed on a public recreation site. There was a proposal to expand the current Pacific Rim National Park Reserve down the west coast of the island to include the Red Creek Fir, and it was also listed by Heritage BC. As of July 2016, both proposals have been unsuccessful. The Red Creek Fir has a diameter of 4.2m, a circumference of 9.8m, and stands at a height of 73.8m. This Douglas fir is estimated to be at least 1000 years old.

Eucalyptus regnans, also known as mountain ash, swamp gum, or stringy gum, is a forest tree species native to Tasmania and Victoria, Australia. It originates from southeastern Australia (Victoria and Tasmania), where it occurs in native forests and extensive plantations. It is widely planted in tropical regions around the world and in subtropical highlands, for example, in the United States, Chile, Spain, India, and Sri Lanka. In New Zealand, it is one of the main cultivated species. In Africa, regnans has been planted in Ethiopia, Kenya, Tanzania, Zimbabwe, and South Africa.

Eucalyptus regnans is the primary gum tree used by the Australian pulp industry and is a favored timber plantation species in southern Africa, New Zealand, and Argentina. The wood (commercially known as Tasmanian Oak) is used for various purposes, including lightweight and heavyweight construction, flooring, boatbuilding, furniture, interior decoration, carpentry, tool handles, kitchenware, posts, barrels, matches, veneer, plywood, particleboard, fiberboard, and wood wool...

Hyperion, a coastal redwood (Sequoia sempervirens) in California, is recognized as the tallest living tree globally, reaching a height of 115.92m. Discovered on August 25, 2006, by naturalists Chris Atkins and Michael Taylor, Hyperion's height was later verified by Stephen Sillett at 115.55m. The tree was found in a remote area within the Redwood National Park, acquired in 1978.

The park also hosts the second and third tallest known trees named Helios and Icarus. Sillett estimates Hyperion to be around 600 years old, while others report it to be approximately 700–800 years old. The tree's exact location is kept secret but can be found on the internet. Researchers suggest that woodpecker activity at the top might have prevented further height growth. In February 2012, the redwood tree Hyperion appeared in James Aldred's BBC Radio 4 documentary, James and the Giant Redwoods.

Lost Monarch, a coastal redwood (Sequoia sempervirens) in Northern California, boasts a trunk diameter of 7.9m (with multiple stems) and stands tall at 98m. It is recognized as the fifth-largest redwood globally in terms of wood mass, with Del Norte Tian claiming the title for the largest single-stemmed coastal redwood, partly due to basic measurements of Lost Monarch incorporating multiple stems. Discovered on May 11, 1998, by botanist Stephen C. Sillett and naturalist Michael Taylor.

The coastal redwood Lost Monarch resides within a cluster of colossal redwoods known as 'The Grove of Titans' in Jedediah Smith Redwoods State Park, although its exact location remains undisclosed to the public to prevent potential ecological disruption or harm. The estimated wood volume of the tree is 988.7 cubic meters, surrounded by other coastal redwoods considered some of the largest in their species. Among the surrounding redwoods, some are named by their discoverers, such as El Viejo del Norte, Screaming Titans, Eärendil and Elwing, Stalagmite, and others.

General Sherman is amongst the world's largest trees by volume, standing at 83m tall with a base diameter exceeding 11m. Its branches remain broad high above. Rising 60 feet above its base, General Sherman has a diameter of 5.3m. Protected by a layer of aluminum material during the KNP Complex Fire, a wildfire caused by lightning, that swept towards Giant Forest. A branch of General Sherman, notably larger than most trees east of the Mississippi River. Considering the colossal size of the Sequoia, one might think it's the oldest tree globally, but that's not the case.

No surprise that General Sherman draws a crowd, which is why the park runs a free shuttle in the summer to two separate stops—one above and one below this magnificent tree. Many visitors disembark at the upper stop and hike downhill to the lower stop, passing by General Sherman on the way, relishing the awe-inspiring feeling of walking around a Sequoia even larger by taking the long Congress Trail loop, a 2-mile circuit through dozens of giant sequoias.

6. Queets River Spruce - Washington, USA

Queets River Spruce, a Douglas fir species, stands prominently along the Queets River Trail about 2.5 miles on Coal Creek, a tributary of the Queets River in Olympic National Park in Washington State. These Spruces thrive in the temperate rainforests of the Pacific Northwest, where ample rain and fog provide the necessary moisture for rapid growth. While their height doesn't necessarily correspond to old age, the largest discovered along the Queets River in Olympic National Park, estimated only 350-450 years old, where others are reported to reach 700 years. Many of the oldest and largest trees were harvested before they could be accurately measured and recorded.

Queets River Spruce gained recognition in the '50s, starting from 1945, as the heaviest and still holds the record for the largest known diameter. This Spruce boasts a minimum height of 61m, a circumference of 15,000mm, and a spread of 22m. It's listed on the national champion Douglas fir list by the American Forest, and one of the few 'unquestionable giant trees' in North America with over 800 points. The bark is almost gray instead of brown. It is smooth when young, with scales instead of ridges when mature. Even compared to other ancient trees in the Pacific Northwest, its bark appears smoother.

Height: 75.6m

Diameter: 4.8m

7. Gothmog - Australia

A visit to the Styx Tall Trees Reserve is incomplete without witnessing the towering White Knights, also known as giant ash, named after the reserve. It's not just their height, with many species reaching over 90 meters, but the girth of these remarkable trees that makes them among the largest and tallest eucalypts on the planet. The Styx Tall Trees Reserve currently safeguards iconic trees like Gothmog, captivating visitors with their powerful individual titles bestowed upon Chapel, Firebird Wonder, Gandalf's Staff, Icarus Dream, and Two Towers.

Gothmog (White Knight) is a species native to the Styx Valley in southeastern Australia. The White Knight is a tall, stout hardwood tree, reaching up to 90 meters in height, with a trunk diameter of 3 meters. Gothmog, with 337 cubic meters, is one of the oldest trees globally. It's one of the few eucalypt species that can rival the giant swamp gum Eucalyptus regnans in size.

8. Tane Mahuta Kauri Tree - New Zealand

Tane Mahuta, also known as the 'Forest God,' stands as a colossal kauri tree in the Waipoua Forest of Northland Region, New Zealand. Its age remains uncertain but is estimated between 1,250 to 2,500 years, making it the largest living kauri tree known to date. Named after the Maori forest god and bird, it is a relic of the ancient subtropical rainforest that once thrived on the Northland Peninsula. Other giant kauri trees, notably Te Matua Ngahere, are found nearby. Tāne Mahuta is the most renowned tree in New Zealand, alongside Te Matua Ngahere.

Tane Mahuta was discovered and identified in early January 1924 during the surveying of what is now State Highway 12 through the forest. In 1928, Nicholas Zakas and other bushmen, who were building the road, also identified the tree. During the New Zealand drought in 2013, 10,000 liters of water from a nearby stream were transported to Tāne Mahuta, which showed signs of water loss. In 2018, the tree was threatened by kauri dieback, a disease often causing death due to a fungus that infected many kauri trees nearby. The New Zealand Conservation Department initiated a plan to protect and rescue the species from kauri dieback.

Height: Approximately 51.2m

This tree is known as the 'Quinault Lake Redcedar.' Found near the northwest shore of Lake Quinault, north of Aberdeen, Washington, approximately 34km (21 miles) from the Pacific Ocean. Situated near Higley Creek in the southwest corner of Olympic National Park, it is the largest western red cedar in terms of volume; Total wood volume is 500m3 according to Robert van Pelt in Forest Giants of the Pacific Coast. It is also the largest tree in the state of Washington and surpasses both Sequoiadendron giganteum and Sequoia sempervirens in size.

Redcedars have been dying off for several years and finally toppled, leaving only a large stump by early 2016. Nicknamed the “Douglas Tree,” the famous redcedar of Kalaloch attracts thousands of tourists each year, daring to venture off the main highway to capture a few photos of the tree. Estimated to be around 1,000 years old, the tree is believed to be the third-largest nationwide.

Diameter: 6.04m

El Arbol del Tule, in Spanish, means the Tule Tree, known to be a tree located in the churchyard in the center of Santa María del Tule town in the state of Oaxaca, Mexico, about 9km east of Oaxaca City on the road to Mitla. It is the Montezuma cypress (Taxodium mucronatum) or ahuehuete (meaning 'old man of the water' in Nahuatl). It has the world's stoutest trunk. In 2001, it was UNESCO-listed as a potential World Heritage Site but was delisted in 2013.

In 2005, the trunk of El Arbol del Tule measured 42.0m in circumference, equivalent to a diameter of 14.05m, an increase from the 11.42m measurement in 1982. However, the trunk was heavily buttressed, so the diameter reading is higher than the actual cross-sectional size of the trunk; accounting for this, the 'smoothed' diameter of the trunk is 9.38m. This tree is slightly wider than the next known stoutest tree, a giant Sequoia with an 8.90m diameter. Height is challenging to measure due to the extensive crown; the 2005 measurement, done with a laser, is 35.4m, shorter than previous measurements of 41-43m.
