What are invasive species?

Invasive species are defined as non-native organisms that, when introduced to a new environment, spread rapidly and cause harm to the ecosystem, economy, or human health. These organisms often outcompete native species for resources such as food and space, disrupt local ecosystems, and can lead to significant biodiversity loss. Their introduction can occur through various means, including human activities like trade, travel, or environmental changes.

The characteristics that classify a species as invasive include not only its ability to reproduce quickly and spread but also its negative impacts on local flora and fauna. For instance, invasive plants might alter soil chemistry, while invasive animals could predate on or compete with native species, leading to declines or extinctions.

Understanding invasive species is crucial for wildlife management and conservation efforts, as controlling their spread is vital to preserving native ecosystems and biodiversity.
