The Pando aspen clone, located in central Utah within the Fishlake National Forest, is currently facing threats from disease, insects, and a lack of new growth. The organism, which spreads via an expanding root system from a single seed, is showing signs of decline that specialists are working to address.
The Trembling Giant's massive scale
Known as the Trembling Giant, Pando consists of over 40,000 individual trees covering approximately 106 acres. While the exact age of the root system is difficult to calculate, it is estimated to have begun at the end of the last ice age.
Causes of the clone's decline
The decline of the clone is attributed to two primary factors: a lack of regeneration and the presence of insects and disease. Researchers believe the lack of new growth may be caused by over browsing from deer and other ungulates.
Threats from insects and disease
Additionally, bark beetles and diseases such as cankers and root rot are attacking overstory trees, which weakens and kills them. Experts warn that the combination of dying trees and insufficient regeneration could eventually result in a smaller clone or a complete die off.
Pando's global recognition and fame
Pando has gained worldwide fame for its massive size and weight. In 2006, the U.S. Postal Service commemorated the clone as one of the 40 Wonders of America with a stamp.
Conservation efforts and research methods
The Forest Service is working in cooperation with partner organizations, such as Friends of Pando, to study and address these issues. Foresters have implemented various methods to stimulate roots and encourage new sprouting, using research plots to track progress and adapt treatments.
Visiting the Utah landmark
Located approximately one mile southwest of Fish Lake on State Highway 25, Pando remains a significant destination for visitors, particularly during the autumn when the leaves turn golden.
