Yellowstone National Park in Park County, Wyoming — The American West (Mountains)
Roots of Survival
The secret of an aspen grove lies hidden beneath the ground. Aspens rarely grow from seeds but spring up abundantly from the roots of their parent. These young shoots are connected to each other underground by an extensive root system and are genetically identical! This method of reproduction is called “cloning.”
Aspens are masters of cloning. Their clones can cover several acres and sometimes live for thousands of years.
Why Do Aspens Tremble?
Trembling. Quaking. Quivering. These words have all been used to describe Populus tremuloides. Aspen leaves flutter in the slightest breeze because of how they are built. Their slender petioles – the stems on each leaf – are flat and at a right angle to the leaf surface. Consequently, the leaves quiver as they catch the wind.
When aspens tremble, light reflects from each shiny leaf, causing the entire grove to shimmer.
