Aspen trees are the most widely distributed tree in North America. A forest of many aspen trees, some of which may be tens of thousands of years old, is actually one single clone. What is likely to be the greatest threat to the long-term survival of aspen forests?
◦ climate change, which alters aspen trees' typical moist and cool environment to dry and warm
◦ a fungus that is often found associated with roots of some trees in the stand
◦ lack of pollinators
◦ insects, which may bore holes in the stems of trees
