Invasive Species Impact and Management

The video explores the topic of invasive species, explaining the differences between native, non-native, naturalized, and invasive species. It highlights the complexities and impacts of non-native species on ecosystems, using various examples and case studies. The video emphasizes that not all non-native species are harmful and encourages a nuanced understanding of their roles.
