The cloning of giant sequoia trees could help combat climate change



An old redwood forest is the cathedral of nature. Light penetrates through the huge trees and dips the ferns and mosses below into an original green glow.

The canopy of a 300-foot-tall, overgrown coastal sequoia makes it funny. Mosses, lichens, fern mats and even other trees grow on the canopy floor.

The Brotherhood Tree, a massive redwood in Klamath, California, harbors a complex habitat for wildlife and its canopy is full of surprises for those who dare the top. Bats flutter into the faces of climbers and hundreds of birds circle over them territorially.

For Jake Milarch, who oversees the tree reproduction in the Archangel Ancient Tree Archive, this is the perfect place to prune small tree specimens of the palm.

"There are several hormones at the top of these trees," he says. "What we hope to get when we multiply or clone a Champion tree is the exact genetics of this tree, which has proven over time that it can deal with adverse conditions."

He will bring these plant samples back to their tree The camp in Michigan to clone and breed them.

Archangel Ancient Tree Archive, an organization dedicated to reforestation as a solution to global warming, was created by Jake's father David, a third-generation tree-grower. David has been a rebel for most of his life and has a mission to save the world by planting trees.

Archangel clones master trees, the largest and tallest of their kind, to preserve their genetics and combat climate change. On this expedition, the team clones the Brotherhood Tree, a tree that they treasure for 1

000 years and whose life began sometime in the Middle Ages.

300 feet is a long way up, with nearly 28 stories a modest skyscraper. Jake Milarch is a certified arborist who started climbing trees at a young age. He climbs to the top of the fraternity tree, backed by Damien Carré of Expedition Old Growth, an adventure tree climbing specialist and Archangel partner.

"What they do is what I want to participate in," Carré says. "We've been able to do some pretty amazing projects that do things for the planet." In helmets and belts, they pull themselves up with ropes.

"We will probably take a few hundred samples," he says. "Once we have collected the basic genetic material in our lab, we really do not have to go back to that tree."

The Milarchs plan to use these clones to supplement and strengthen depleted redwood forests and even migrate them as climate change begins to affect the trees in their natural habitats. They have already planted sequoia trees in the San Francisco Presidium and plan to plant these clones around the world.

New research published in Science Magazine this month seems to confirm Archangel's mission and suggest that planting trees could be an effective strategy to mitigate climate change. The study recommends planting one billion acres of canopy around the globe to absorb large volumes of carbon that fuels climate change – nearly 205 gigatons.

According to a recent study by Humboldt State University and the University of Washington, redwood sequesters bind more carbon than other forests. An old-growth sequoia forest promotes biodiversity, binds more carbon and has more regenerative properties than younger forests.

The Latin name of a coastal sequoia is Sequoia sempervirens and means "forever green" or "forever alive". "and these trees can live for thousands of years. Sequoias have a thick and tannin-rich bark that makes them resistant to insects and fire, so they have few natural enemies."

But they have one major problem – humans.

"It's a beautiful wood," says Steven Meitz, Superintendent of Redwood National State Parks, "It is very decay-resistant and very decay-resistant."

The coastal redwood forests were decimated by commercial logging in late 19th century to the extent that only 5 percent of the old forest vegetation remains. "Man was responsible for reducing the entire habitat of the Coast redwoods," says Meitz.

The Redwood National State Parks teamed up with Save the Redwoods League to Try to accelerate the regeneration of Titan trees.

Redwoods Rising is hoping this public-private partnership to restore the deforested forests of old growth. They clear the dense wooden mats on the forest floor from the second growth trees and sell the wood. The proceeds will help rebuild the redwoods and dilute some for others to survive.

Your goal is to put the second forest on the right track to become an old grove. Granted, it's a long process, but Meitz believes that it is necessary to reverse the human-caused environmental damage, and hopes that this will be a generation project.

Very fat, it could take thousands of years, "says Meitz.

But he adds optimistically," We hope to accelerate that and reduce it to hundreds of years. "
