Bioregion: A region defined by a combination of ecological characteristics (e.g., watersheds, soil types, native species) and human cultural elements (e.g., local communities, traditional land use). Bioregions are typically larger than landscapes but smaller than ecoregions, emphasizing a sense of place and human-nature integration. For example, the South Florida Bioregion might include the Everglades, adjacent wetlands, and human communities tied to these ecosystems.
