“While Pando has likely existed for thousands of years – we have no method of firmly fixing its age – it is now collapsing on our watch,” Rogers says. tremula, are “among the most widespread tree systems in the world”, but they are threatened by human impacts such as global warming, deforestation, fire suppression, and unchecked herbivore grazing. Their report, published in the journal PLOS One, says aspen forests, which contain chiefly P. Rogers and McAvoy say their Pando findings have global implications. But, in fact, it is an individual comprising about 47,000 genetically identical male aspen ramets, or above-ground stems, and one massive root system weighing about 6 million kilograms. The organism, known as Pando (which means “I spread”, in Latin), is outwardly a forest of quaking aspen trees ( Populus tremuloides) occupying 43 hectares in Utah’s Fishlake National Forest. One of the largest living organisms on planet Earth is in peril and in need of urgent attention, according to a study by researchers Paul Rogers and Darren McAvoy, from Utah State University, in south-western US.
