WHAT DO WE MEAN BY "INVASIVE"?

An invasive species is alien or foreign to the ecosystem in consideration and causes environmental, economic and or human harm. While they may appear to be quite pretty in appearance, these species are dangerous to ecosystems.

Invasive plants have the potential to grow so rapidly that they can cover the entire under-story of a forest!
Native plants would be displaced as a result because they would not be able to get access to space and sunlight for growth.
