What is a critical impact of invasive plant species on local ecosystems?

Invasive plant species can significantly disrupt local ecosystems primarily by outcompeting native species for resources such as light, nutrients, and space. This competitive advantage often leads to the decline or even elimination of native plants, resulting in reduced biodiversity. Biodiversity is crucial for ecosystem stability and resilience, as it supports various ecological functions and services. When invasive species dominate an area, the variety of native flora and fauna can diminish, leading to a loss of habitat for native wildlife and a decline in ecosystem health. This impact can cascade through food webs and affect various trophic levels, further altering the ecological balance within the habitat. Thus, the reduction of biodiversity driven by invasive species is a critical concern for the integrity of local ecosystems.
