The Wisdom of Ancient Trees

We are pleased to share with you an Earth Day essay written by Thomas Wentworth, PhD, inspired by his experience at the "Three Sisters Swamp" of the Black River in eastern North Carolina. Tom is Alumni Distinguished Undergraduate Professor, Emeritus,  Department of Plant & Microbial Biology, North Carolina Statue University.

​I visited BLK227 on a Tuesday for an interview. BLK227 is a Baldcypress tree (Taxodium distichum for the botanists) in the Three Sisters Swamp section of the Black River, a bit west of Burgaw, North Carolina. BLK227 was so named by Dr. David Stahle, who runs the Tree Ring Laboratory in the Department of Geosciences at the University of Arkansas in Fayetteville. BLK227 holds the current world record for documented age of any Baldcypress tree, 2,629 years old this year. That’s a minimum age, by the way, because Dr. Stahle had to core BLK227 at a height of 10 feet above the swamp floor, and it is unknown how long it takes for a Baldcypress seedling to reach 10 feet in height. That minimum age is impressive - that’s 629 years Before the Common Era. BLK227’s age firmly establishes Baldcypress as the oldest wetland tree species on Planet Earth, and number five on the worldwide list of the oldest known continuously living, sexually reproducing, non-clonal tree species based on dendrochronology, the scientific study of tree rings. < click "Read More" below right >
