Biological invasion, commonly referred to as invasive species or alien species, occurs when non-native organisms are introduced into an ecosystem where they establish, reproduce, and spread rapidly, often causing harm to the environment, economy, and human health. These species can include plants, animals, fungi, and microorganisms. Biological invasions pose significant challenges to sustainable development due to their ecological and economic impacts at the local level.

Ecological Impacts:

1. Disruption of Native Ecosystems: Invasive species can outcompete native species for resources such as food, water, and habitat, leading to the decline or extinction of indigenous flora and fauna. This disruption can result in imbalances within ecosystems, affecting ecological processes such as nutrient cycling and energy flow.
