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 ecosystems, economy, or human health. This definition highlights the critical aspect of invasiveness: these species often thrive in new habitats due to a lack of natural predators, leading them to outcompete native species for resources, disrupt local ecosystems, and alter habitats.

The focus on non-native organisms is essential because it indicates that these species are not originally from the area they invade. Their introduction, whether intentional or accidental, often leads to detrimental effects on local biodiversity, causing native populations to decline and ecosystems to become unbalanced.

Understanding invasive species is vital for implementing effective management strategies in agriculture, conservation efforts, and public health, as they can impact crop production, wildlife management, and the spread of diseases.
