In both the north and south, from Jedediah Smith Redwoods State Park to Pfeiffer Big Sur State Park, lichens — science-fiction-like organisms that exist as symbiotic assemblies of fungi and algae or cyanobacteria — make up most of the species identified.
About 17,000 lichen species are known worldwide, although much about them remains unknown — for example, the potential uses for the more than 600 unique compounds that lichens are known to produce. Some of them are already being used today as antibiotics in soaps and deodorants, and others as ingredients in traditional treatments for constipation, arthritis and kidney diseases; others still are being investigated as cancer-fighting agents. “Potentially, we could find some compounds that could be beneficial to humans,” Dr. Næsborg said. “We really don’t know what we’d be missing if we don’t climb the trees.”
In Mr. On Easter Sunday, Mr. Mr. “I think the best outcome of these guided climbs is that most participants are humbled,” he said. Historic 'Drive-Through' Sequoia Tree Was Felled by California Storms. One of California's most famous trees fell victim to this weekend's storms, according to the Los Angeles Times.
The historic Pioneer Cabin Tree, a former "drive-through" giant sequoia in Calaveras Big Trees State Park in Calaveras County, was reported toppled by 2 pm on Sunday. A volunteer at the park, Jim Allday, told SF Gate that the tree "shattered" upon impact to the ground. The Pioneer Cabin Tree had been hollowed out in the 1880s so hikers and horses, then later cars, could drive through it. The idea was based on the hollowed-out Wawona Tunnel Tree, which was killed by the process and then fell in a storm in the 1960s. RELATED: Millions of US Trees Are Dying The Pioneer Cabin Tree had lived despite the carved hole, however, and was believed to be hundreds of years old. "We lost an old friend today. The tree's root system apparently could not withstand the heavy rains and strong winds that lashed northern California over the weekend.
WATCH: Are Floods the Worst They've Ever Been? Celebrate Earth Day With a 4,800-Year-Old Tree (If You Can Find It) The forest service is so protective of its ancient, gnarled star that it will not even share its picture.
Officials say they fear that an image might enable a particularly determined visitor to track down its precise location in Central California’s Inyo National Forest. At 4,847 or so years old, Methuselah is the world’s oldest known living tree, which makes it — in the mind of its human protectors — too old for guests. The tree did not make it through several thousand years of civilization only to be either harassed by a horde of Instagrammers eager to carve their names in its bark or assassinated by a reckless researcher. It has happened before. Japanese 'miracle' pine returns to tsunami-hit town. A pine tree that became a symbol of hope after it survived the March 2011 tsunami in north-east Japan was opened to the public in the devastated town of Rikuzentakata on Wednesday.
The 250-year-old "miracle" pine – the only one among 70,000 trees left standing along the town's coastline after the disaster – initially survived, but was removed last September after its roots died from exposure to salt water. Experts preserved the 27-metre (89ft) tall tree in its near-original state by inserting a metal skeleton into its trunk and adding replica branches and leaves made from a synthetic resin.

Conifers' helicoptering seeds are result of long evolutionary experiment. The whirling, winged seeds of today's conifers are an engineering wonder and, as University of California, Berkeley, scientists show, a result of about 270 million years of evolution by trees experimenting with the best way to disperse their seeds.
The first conifer species that produced seeds that whirl when they fall used a variety of single- and double-winged designs. Whirling, or helicoptering, keeps a seed aloft longer, increasing the chance that a gust of wind will carry a seed to a clearing where it can sprout and grow unimpeded by competitors "Winged seeds may have contributed to the success of these conifers," said paleobotanist Cindy Looy, an assistant professor of integrative biology at UC Berkeley, a member of the Berkeley Initiative for Global Change Biology (BiGCB) and a curator with UC Berkeley's Museum of Paleontology.
Today, however, all conifer species whose seeds whirl as they fall appear to have settled on only one type of design: asymmetrical and single-winged. The Sex Lives of Christmas Trees. Big Data and the Science of the Christmas Tree. Jill Wegrzyn, assistant research professor of ecology and evolutionary biology.
Wegrzyn is helping develop bioinformatics tools that will enable more scientists to find meaning in massive amounts of data, such as those on crop production. (Sean Flynn/UConn Photo) Often called the “Cadillac of Christmas trees,” the Fraser Fir has everything a good Christmas tree should have: an even triangular shape, a sweet piney fragrance, and soft needles that (mostly) stay attached and won’t leave tiny stabs in your fingers.
But even Frasers eventually turn, and by the New Year, what was once a beautiful sapling has started to smell like decomposing wood and litter its needles across your living room floor. So scientists who refine the breeding of these and other practically perfect crops are always looking for new ways to understand how trees grow best. “It’s one of the ongoing hurdles of data analysis. Researchers now use drone technology to survey forests and orchards. » In Praise (and Fear) of the Coconut. Christian Primeau is NYBG‘s Manager of the Enid A.
Haupt Conservatory. Cocos nucifera dotting the Dominican coast Winter is coming. It’s only a matter of time before you’ll be climbing crusty brown mountains of ice and snow at street corners, fording knee deep slush puddles, or creeping down the Bronx River Parkway in your car at speeds that give the illusion you’re traveling in reverse (this all assumes our unseasonably warm fall turns a sharp corner). But before you jet off to the tropics for well-deserved respite, beware an unheralded danger. Baobab. The Obliging Manna Ash.
