Oldest known tree in eastern North America documented – ScienceDaily

A recently documented bald cypress tree in North Carolina, including a tree at least 2624 years old, is the oldest known living tree in eastern North America and the oldest known wetland species in the world. David Stahle, Distinguished Professor of Earth Sciences, along with colleagues from the University's Ancient Bald Cypress Consortium and other conservation groups, discovered the 2017 trees in a forested wetland preserve along the Black River south of Raleigh, North Carolina. Stahle documented the age of the trees using dendrochronology, the study of tree rings and radio carbonation. His findings were published on May 9 in the journal Environmental Research Communications . The old trees are part of an intact ecosystem that stretches over the 65 mile length of the Black River. In addition to their age, the trees are a scientifically valuable way of reconstructing old climatic conditions. The oldest trees in preserves extend the paleoclimatic record of the southeastern United States by 900 years and show signs of drought and floods during colonial and pre-colonial times that exceed all saturation in modern times. "It is unusually rare to see an old tree growth tree along the entire length of a river like this," Stahle said. "Bald cypress is valuable for timber and they have been heavily logged in. The road less than 1 percent of the original virgin cypress forests have survived." Stahle has been working in the area since 1985 and cataloged bald cypresses as old as 1700 years in a 1988 study…

A recently documented bald cypress tree in North Carolina, including a tree at least 2624 years old, is the oldest known living tree in eastern North America and the oldest known wetland species in the world.

David Stahle, Distinguished Professor of Earth Sciences, along with colleagues from the University’s Ancient Bald Cypress Consortium and other conservation groups, discovered the 2017 trees in a forested wetland preserve along the Black River south of Raleigh, North Carolina. Stahle documented the age of the trees using dendrochronology, the study of tree rings and radio carbonation. His findings were published on May 9 in the journal Environmental Research Communications .

The old trees are part of an intact ecosystem that stretches over the 65 mile length of the Black River. In addition to their age, the trees are a scientifically valuable way of reconstructing old climatic conditions. The oldest trees in preserves extend the paleoclimatic record of the southeastern United States by 900 years and show signs of drought and floods during colonial and pre-colonial times that exceed all saturation in modern times.

“It is unusually rare to see an old tree growth tree along the entire length of a river like this,” Stahle said. “Bald cypress is valuable for timber and they have been heavily logged in. The road less than 1

percent of the original virgin cypress forests have survived.”

Stahle has been working in the area since 1985 and cataloged bald cypresses as old as 1700 years in a 1988 study published in the journal Science. His work contributed to preserving the area, where 16,000 hectares were then purchased by Nature Conservancy, a private land conservation group that holds most of its facilities open to the public.

“Dr Stahle’s original work on the Black River, which showed trees from Roman times, inspired us to start preserving the blacks more than two decades ago,” said Katherine Skinner, executive director of the North Carolina chapter of the Nature Conservancy. This ancient forest gives us an idea of ​​how much of the North Carolina coastline looked like a thousand years ago. It is the source of inspiration and an important ecosystem. Without Dr. Stahle would have gone unprotected and probably destroyed. “

For the latest study, researchers used non-destructive nuclear samples from 110 trees found in some of the wetland forests they had not visited before.” The area of ​​ancient growth bald cypress was 10 times bigger than I realized, “Stahle said.” We believe there are older trees out there. “Story Source:
