The article discusses how restoring forests invaded by non-native plants is crucial for maintaining healthy ecosystems. The researchers focused on reestablishing seed dispersal interactions disrupted by invasive species. They studied a 25-year-old forest invaded by non-native plants that attract birds for seed dispersal. The removal of these invaders is vital to restore the balance between native plants and birds in the ecosystem. The researchers found that controlling invasive plants and promoting native species can help rebuild the natural seed dispersal network. It's essential to manage these invasive species at a landscape level to prevent their return and preserve biodiversity in restored forests.
