Slender white trunks reaching skyward and leaves fluttering even in the gentlest breeze—aspens are a symbol of the American wilderness. These trees are the most widespread native species in North America, with Pando, located in Utah's Fishlake National Forest, being a massive quaking aspen grove. Their fall foliage is breathtaking, with their leaves turning a vibrant yellow that lights up the landscape, as seen in today's photo, which was taken near Marble, Colorado.

Aspens are not only beautiful but also biologically fascinating. They grow in large colonies that originate from a single root system, making them some of the largest living organisms on Earth. Each tree in the colony is genetically identical. When an aspen tree is cut down or damaged, the root system remains alive, allowing new shoots to emerge and grow, which helps create a resilient network that can survive harsh conditions, including wildfires. This species quickly colonises areas that have been recently burned down and can regenerate even after frequent fires. Closer to home. the Aspen parkland is an ecological region that —retches across 397,304 square kilometres, covering parts of Alberta, Saskatchewan and Manitoba. Aspen trees are more than just a treat for the eyes; they are an example of nature's resilience.
