TEES ALIEN INVADERS
WHAT IS AN ALIEN INVADER?
Alien Invaders, also referred to as Invasive Non-Native Species (INNS), are those animals and plants that have been transported outside of their natural range and that can damage our environment, environmental services, the economy, our health and the way we live. Impacts of INNS are so significant, they are considered to be one of the greatest threats to biodiversity worldwide. They threaten not only the survival of rare native species and damage sensitive ecosystems and habitats but can, over time, remove even the most common species from an area through aggressive colonisation.
