According to the available information, the tree that is banned in India is the Conocarpus tree, also known as Saptaparni locally. The civic bodies in Gujarat have been planting thousands of these trees in recent years. However, the government has issued orders to chop them down due to their environmental and health hazards. It is not specified why exactly the Conocarpus tree has been banned, but it can be assumed that its negative impacts on the environment and human health have led to the ban.
