Christmas trees are dead or dying. But some conifers and other trees theoretically could live forever, according to a recent essay that reviews accumulating evidence on extremely long-lived trees—and calls for more scientifically rigorous methods to determine their age and study their longevity.

Their essay was published in the August issue of New Phytologist.
David Stahle, a geographer and tree longevity researcher at the University of Arkansas, who was not involved in the review essay, used words such as “excellent” and “comprehensive” to describe it. But he takes issue with the assertion that trees can potentially live forever. “The likelihood, all things being equal, that trees are immortal seems improbable to me,” he says. “I love the idea. It’s a romantic idea, but, I mean, come on.
