• Age: They can live for over 2,000 years, with many reaching an age of 500 to 700 years.

Importance and Characteristics

*Sequoia sempervirens* is not only significant for its height but also for its ecological role. These trees provide important habitat for many species and contribute to the forest ecosystem's health. The bark of these trees can be up to 30 cm thick, providing protection from fire and pests.

In addition to their impressive height, these trees also have an exceptional ability to regenerate. New shoots often sprout from the base of older trees, allowing them to survive after storms, fires, or even when the main trunk is damaged.

Conclusion

*Sequoia sempervirens* stands as a remarkable example of the grandeur and resilience of nature, holding the title of the tallest tree in the gymnosperm category and an important species in terms of both its size and ecological significance.
