Habitat loss and fragmentation have significantly impacted ecosystems in Southern Ontario. Originally containing extensive forests, the landscape is now dominated by human settlements, farmland, and transportation routes as natural areas have been cleared and divided into smaller parcels. This reduces biodiversity as some species require large intact habitats. Examples of threatened species include the loggerhead shrike whose grassland habitat has declined. Wetlands have also been extensively drained for agriculture, diminishing these important aquatic ecosystems. Conservation efforts now aim to protect remaining areas and restore degraded habitats.
