Dear Friends of the Eastern Sierra Land Trust,
We wanted to take a moment to address an important action that we recently undertook at our office on Fowler Street in Bishop. As part of our ongoing commitment to preserving the integrity of our region’s ecosystems, we made the difficult but necessary decision to remove seven large Tree of Heaven (Ailanthus altissima) trees from the landscape.

The Tree of Heaven is a highly invasive species that poses a serious threat to the biodiversity of the Eastern Sierra. Although these trees may seem harmless at first glance, they have significant ecological impacts, particularly on native plants and wildlife. Here are the key reasons behind this decision:

Ecological Harm

The Tree of Heaven is known for its aggressive growth and ability to outcompete native species. It spreads rapidly and can dominate large areas, reducing habitat for native plants that are essential for local wildlife. Additionally, it secretes chemicals into the soil that is toxic to surrounding plants. By removing these trees, we are making space for native species to thrive and promoting a healthier, more balanced ecosystem.

Host to a Destructive Pest

In addition to its invasive nature, the Tree of Heaven serves as a primary host for the Spotted Lanternfly (Lycorma delicatula), an invasive pest that has been causing significant damage to agriculture and natural ecosystems across the country. The Spotted Lanternfly poses a serious risk to many crops, including grapes, stone fruits, and other economically important plants, as well as to native trees.
By removing these trees now, we are actively preventing the establishment and spread of the Spotted Lanternfly in our region, helping to protect both natural and agricultural resources.

Supporting Native Wildlife and Plants

One of the core missions of the Eastern Sierra Land Trust is to protect critical wildlife habitats. Removing invasive species like the Tree of Heaven allows us to better support native plants, which provide food and shelter for native species. The California Native Plant Society- Bristlecone Chapter has generously donated replacement plant species to take their place that will be planted in the years to come.

Skyline Arborists worked swiftly and safely to remove 7 large invasive Trees of Heaven from ESLT's office.

Learning to identify the spotted laternfly will be crucial to stop the spread.

Mature trees, like the ones we removed, can produce over 300,000 seeds a year!

We understand that cutting down large trees can sometimes be concerning, especially when they provide shade or visual appeal. However, our priority is the long-term health of the entire ecosystem, and we are confident that this action will lead to a stronger, more resilient landscape for future generations.

We greatly appreciate your support and understanding as we continue our work to protect the Eastern Sierra’s natural beauty and ecological diversity. If you have any questions or concerns, please don’t hesitate to reach out.

This project was funded by a donation from one of ESLT’s board members and Skyline Tree Service generously provided a discount on their services.
