Can I Touch Tree of Heaven?
Tree of heaven (Ailanthus altissima) is a medium-sized tree species native to Asia, now widely distributed across the United States and other parts of the world. While it may seem like a harmless or even attractive tree, some people may wonder if they can touch or interact with it. In this article, we’ll delve into the safety and precautions necessary when handling tree of heaven.
Handling Tree of Heaven: Be Cautious
Before touching a tree of heaven, be aware that its sap or resin can cause skin rash or irritation in some people. This is primarily due to the presence of urushiol, the same allergen found in poison ivy and sumac. While minor reactions may not be a significant concern, severe irritation or allergic reactions can happen, especially if you already have sensitive skin.
In addition to the sap issue, tree of heaven roots can grow aggressively, spread quickly, and cause damage to nearby structures, including pavements, sidewalks, and buildings. Be wary of roots growing under foundation walls or near utility pipes.
Skin Protection and Precautions
To minimize the risk of skin irritation when handling a tree of heaven, observe the following precautions:
- Wear long sleeves, long pants, and gloves when cleaning or pruning the tree. This will prevent direct exposure to the sap or urushiol.
- Wash your skin thoroughly with soap and water after handling the tree, especially if you touch the sap or any tissues with urushiol. Repeat washing if urushiol is still detected.
- Avoid touching your face, especially your eyes, lips, or mouth, immediately after handling the tree of heaven.
- Wear protective clothing, including a mask, to prevent inhaling airborne fragments of the tree or contacting sap particles.
**Trees of Heaven and Wildlife
While tree of heaven trees are not typically preyed upon by insects due to the chemicals in their wood and bark, there have been instances where certain types of fungi have been attracted to the tree. In particular, the Verticillium albo-antrum fungus may infect and kill the tree, potentially spreading to adjacent native species.
Conversely, some creatures, like deer, insects, and birds, rely on tree of heaven plants for food or shelter.
**Tree of Heaven Spread and Control
Seed dispersal by birds or other animals contributes significantly to the rapid spread of tree of heaven. However, humans can inadvertently or intentionally spread the tree seed through:
- Compost or mulch usage
- Land clearance or construction activities
- Intentional tree planting
To control spread, consider the following techniques:
- Eradicating infested seedlings before they germinate
- Appointing a designated arborist to maintain infected areas
- Treating affected areas with biological or chemical controls
Conclusion
In conclusion, can you touch tree of heaven? While it’s feasible to interact with the tree, exercise caution, as the sap and allergens present can cause harm. Follow proper safety and protection measures to minimize any potential risks. Be informed about the tree’s habit of spreading and control mechanisms to prevent unwanted spread to native ecosystems.
