Aspen trees can reproduce sexually or asexually

So if there were other comparably sized clonal colonies,they may have perished then.Meanwhile, Pando’s corner of Utah remained glacier-free.The soil there is rich in nutrients that Pando continuously replenishes;as it drops leaves and trunks,the nutrients return to nourish new generations of clones.Which brings us to the third cause of Pando’s size: cloning.Aspens are capable of both sexual reproduction—which produces a new organism—and asexual reproduction—which creates a clone.
