What is Biological Invasion? What are its ecological and economic impacts at local level.

Biological invasion, also known as biological or species invasion, occurs when non-native species establish themselves and spread rapidly in a new environment, often causing harm to native species, ecosystems, and human activities. These invasive species can include plants, animals, fungi, and microorganisms, and they are introduced intentionally or unintentionally by human activities such as trade, travel, or accidental release.

At the local level, biological invasions can have significant ecological and economic impacts:
