How do habitat restoration projects address both invasive species and native species?

Habitat restoration projects address the dual challenges of invasive and native species through a combination of active management and ecological planning. Because invasive species often thrive in degraded environments by outcompeting indigenous organisms for resources, restorationists prioritize their removal to create space for native recovery.123

These projects typically employ the following strategies:

• Removal of Invasive Species: Specialists use various methods, such as mechanical removal, herbicides, or biological control—the introduction of natural predators or parasites—to eradicate nonnative populations.453
• Reintroduction of Native Species: Once invasive threats are mitigated, restorationists actively replant or reintroduce native species. Success often depends on selecting the right mix of species, sometimes guided by historical records or remnant patches of original habitat.235
• Restoring Ecological Processes: To ensure native species can sustain themselves, projects often restore natural disturbances, such as prescribed fire or flooding, which help native plants flourish while suppressing invasive weeds.562
• Ongoing Monitoring: Because restoration is a long-term process, regular monitoring is essential to manage adaptive management goals, allowing for the continual eradication of reappearing invasives and further native reintroductions.72

By integrating these actions, restoration efforts aim to reverse biodiversity loss and build resilient, self-sustaining ecosystems.73
