The World’s Largest Known Organism In Trouble

Living on Earth

Karen Mock, Professor of Molecular Ecology at Utah State University tells host Steve Curwood that precise estimates about the age of Pando are not currently possible, but it may be many thousands of years old. But according to Paul Rogers of the Western Aspen Alliance, over grazing from deer and elk are now threatening the massive tree’s existence.
