The significance of using native species in ecological restoration lies in their ability to support existing ecosystems and enhance local biodiversity. Native plants are adapted to local conditions and often provide essential habitat and resources for native wildlife. Their reintroduction can help restore ecological functions that may be lost due to invasive species or habitat degradation. Additionally, using native species reduces the risk of introducing non-native organisms that could disrupt local ecosystems. Ultimately, employing native species in restoration projects promotes ecosystem stability and resilience.
