It's great to know that it can become a big tree in a thousand years,Perry's nearly knee-deep, bright green seedlings are part of an unusual project to grow offspring from the world's largest and oldest trees to see what genes help parents survive. How long will it protect new growth from the hazards of the weather? Change.The effort was led
by the Archangel Ancient Tree Archive, a Michigan nonprofit that preserves the genetics of old trees. It is one of many special measures taken to save giant sequoias that were once considered nearly fireproof. But there is a risk of being washed. out with more intense wildfires.
Giant sequoias are the largest trees in the world by volume and closely related to the world's tallest redwoods. Sequoias grow naturally only in a 260-mile (420-kilometer) long forest belt on the side slopes. Western Sierra Nevada Mountains They have large trunks and can grow to over 90 meters. Coastal redwoods are slender and native to the Pacific Ocean in Northern California.
Giant sequoia - and redwood - are the best fire-adapted plants. The thick bark protects its trunk. and their canopy is so high that they are far from the flames. Sequoias also rely on fire to help open the cones to separate the seeds, and the flames wash the undergrowth so that the seedlings can take root and receive sunlight.
