What is the fastest growing tree?

The fastest growing tree species varies depending on a number of factors such as location, climate, and growing conditions. However, some species that are known for their fast growth rates include:

• Eucalyptus: This Australian native can grow up to 9 feet per year and is often used for pulp, paper, and construction.

• Paulownia: Also known as "Princess Tree" or "Empress Tree," Paulownia is a fast-growing deciduous tree that can grow up to 10 feet per year and is known for its valuable wood products.

• Hybrid Poplar: This tree is a hybrid of eastern cottonwood and balsam poplar, and it can grow up to 10 feet per year, making it a popular choice for reforestation and agroforestry projects.

• Leucaena leucocephala : Fast growing tropical leguminous tree, it can grow up to 20ft per year, providing valuable biomass and has been used for agroforestry and animal feed.
