- [Invasive Species](/ap-enviro/key-terms/invasive-species): Invasive species are non-native organisms that cause harm to an ecosystem they invade. They often thrive in modified habitats where native species struggle to survive.
- Fragmentation: Fragmentation occurs when large areas of continuous habitat are divided into smaller patches due to human activities like road construction or land development. This can isolate populations and limit their ability to migrate or find resources.
- [Urbanization](/ap-enviro/key-terms/urbanization): Urbanization refers to the process of transforming rural areas into urban ones through the construction of buildings, roads, and infrastructure. It often leads to habitat loss and fragmentation for many species.
