Giant sequoias (over 3,000 years old) The President, in California's Sequoia National Park, is estimated to be over 3,200 years old. The world's largest tree, General Sherman — also located in Sequoia National Park — is estimated to be about 2,200 years old.

One of the most famous trees estimated to be approximately 3,000 years old is the Tāne Mahuta, located in the Waipoua Forest of the North Island, New Zealand. Known as the "Lord of the Forest" in Māori culture, it is a giant Kauri tree (Agathis australis) with a massive trunk circumference of over 45 feet. Another contender for this age bracket is the Olive Tree of Vouves on the island of Crete, Greece, which is still producing olives today and is widely considered one of the oldest olive trees in the world. For even greater antiquity, the Methuselah (a Great Basin Bristlecone Pine) in the White Mountains of California is over 4,800 years old, while the "Old Tjikko" in Sweden is a clonal Norway Spruce with a root system dated to over 9,500 years. These ancient wonders are strictly protected, and in the case of Tāne Mahuta, visitors must use specialized foot-cleaning stations to prevent the spread of Kauri dieback disease.
