But understory structure may also be complex with multiple layers of shrubs and herbs, or relatively simple herb layers dominated by forb or graminoid species.
How do aspen trees reproduce?
A stand of aspen trees is actually one giant organism, a large clonal colony which has reproduced from a single seed and spread by root suckers. When the sun falls on earth and warms the soil, it stimulates the clone to send up suckers which become full-grown trees. So what looks like a stand of individual trees, is actually one genetic individual which can cover hundreds of acres and weigh thousands of tons. In fact aspen clonal colonies are Colorado’s largest living organism.
