What are invasive species?

Invasive species are defined as non-native organisms that, when introduced to a new environment, can cause significant harm to the ecosystem, economy, or human health. This definition highlights that invasive species often disrupt local habitats, outcompete native species for resources, and can alter the environment in ways that harm existing flora and fauna.

The emphasis on being non-native is crucial, as it distinguishes invasive species from those that are a natural part of the ecosystem. While some non-native species may not cause harm and can coexist with native species, those identified as invasive typically exhibit aggressive growth, reproduce quickly, and thrive in the new environment to the detriment of the local species.

Understanding this concept is essential in managing ecosystems and protecting native biodiversity, as the introduction and spread of invasive species can lead to long-term ecological changes. This is why recognizing the characteristics and impacts of invasive species is critical for anyone involved in turf and ornamental management.
