Preserving native plant species is significant in ecosystems because they provide essential habitat and food resources for local wildlife. Native plants are adapted to the local environment and contribute to soil health, water retention, and nutrient cycling. Their presence helps maintain ecological balance and supports biodiversity by fostering complex interactions with indigenous flora and fauna. In contrast, non-native species can disrupt local ecosystems, often outcompeting native plants and leading to declines in local species. Conservation efforts focused on preserving native plants are key to sustaining healthy, functioning ecosystems.
