Ailanthus altissima, commonly known as the Tree of Heaven, is an invasive plant species found in many parts of the world, including the Comunidad Valenciana. Known locally as ailanto, this deciduous tree is recognized for its rapid growth and ability to thrive in a variety of conditions.

Here are some key characteristics of Ailanthus altissima:

• Appearance: The Tree of Heaven typically reaches heights of 15 to 25 meters. It has long, compound leaves with 10-41 leaflets, each with a distinctive twisted tip and a slightly unpleasant odor when crushed.
• Bark and Flowers: The bark is smooth and light gray, reminiscent of the skin of a young elephant. It produces small yellow-green flowers in large clusters, which are followed by clusters of winged seeds known as samaras.
• Habitat: This hardy species can thrive in a wide range of environments, from urban landscapes to rural areas. It is often found in abandoned lots, along roadsides, and in disturbed habitats.
• Impact: Due to its aggressive nature and ability to outcompete native species for resources, Ailanthus altissima is considered invasive. It spreads quickly through both seed production and a robust root system that produces suckers.

Despite its invasive nature, the Tree of Heaven has been planted in urban areas for its ornamental value and its ability to withstand difficult conditions. However, efforts are ongoing in the Comunidad Valenciana to control its spread and mitigate its impact on local ecosystems.
