Autumn will be here sooner than we think, meaning we’ll be admiring all the fall foliage, particularly that coming from aspen trees. Learn more about one of Colorado’s most striking trees with ArborScape!
While holding the title aof ‘largest living organism’, Aspens play an important role in Colorado’s biodiversity, as they support a wide range of wildlife that other trees here don’t. It also helps that they grow well in higher altitudes, can survive in a range of soil types, and have a high moisture content that can help protect them from drought and wildfires.
In fact, aspen trees (along with wildflowers) are usually the first types of plants to move into a burned area to start regrowth in the area. Though it can take twenty to thirty years for aspens to regenerate after a fire, that’s much quicker than other species.
One of the reasons aspens grow so quickly is because the trees in this family grow from a single root structure. With lateral-growing roots, they can sprout shoots up through the ground that become trees that are genetic replicas of each other.
Because these trees share the same genetic markings, they’ll all turn the same color at the same time come autumn.
These trees also continue to grow during winter. Their bark is what performs photosynthesis instead of the trees, which allows the tree to create a green, sugary layer of nutrients that feeds local wildlife.
How to Recognize Aspen Trees
While aspens can be relatively easy to recognize, they can also closely resemble a birch, so here are some things to keep an eye out for when it comes to recognizing aspen trees.
The bark can be fairly easy to recognize, with its greenish-gray coloring and smooth texture, though it does have noticeable lenticels, which are holes that help the tree breathe. The bark can also sometimes be stick to the touch due to the sugars it produces.
Their leaves are rounded into a bit of a heart shape, with slightly rounded teeth around the edge. More noticeable is when the wind blows through these vibrant leaves and creates that “quaking” appearance that aspen trees are so popular for.
Aspen Tree Health
While aspen trees are quite hardy, requiring tons sunlight over other environmental aspects, they are still susceptible to pests and disease. So, in order to keep these trees healthy, here are some things to look out for:
- Aphids
- Leaf Miners
- Sawflies
- Caterpillars
- Poplar borers
- Blight
- Ink Spot disease
- Scale
- Canker
- Trunk Rot
