The redwood's lifespan can frequently last 600 years. In some cases, redwoods have been documented to reach 2,000 years.
The resilience of redwoods trees is attributed to many different factors. The redwoods are resistant to threats, such as fire and damaging insects. Their wood contains tannin, which makes them immune to insects. Their thick bark protects them from fire.
The soil that they grow in also contributes to their growth. The forests where they live contain a wide variety of other trees and plants that reinvigorate the soil when they die.Learn more about Botany
