The Synergy Between Beavers & Aspens

To understand the beaver, you have to understand the aspen. Here in #colorfulcolorado, the two are inseparable partners in shaping the landscape. The aspen plays three critical roles in a beaver’s life:
First, it’s their perfect food. Beavers L.O.V.E aspen. They ignore the woody core and peel the bark to eat the cambium: the sweet, living tissue beneath, packed with nutrients for the long winter.
Second, it’s their go-to construction material. The remaining logs and branches are the literal foundation of their dams and lodges. With aspen, they engineer entire wetlands from scratch, creating the ponds that define these mountain ecosystems.
Finally, and most importantly, it’s their catalyst for renewal. This is where the real magic lies. When beavers cut an aspen, the tree’s vast root system responds by sending up a dense thicket of new shoots, a process that keeps the entire grove young and vibrant. Their dams then hold water, raising the water table and creating the damp, rich soil that helps these new aspens thrive. How cool is that?
It’s a perfect, self-sustaining cycle. The aspen supports the beaver, and the beaver’s work creates a world where the aspen flourishes. Protecting one is how we protect the other.
What part of this partnership (the food, the engineering, or the renewal) fascinates you most? LMK in the comments!!
Little did I know that this dam would soon become a good friend of mine.
