Bio-regional boundaries exist in regards to ecological realities as apposed to political boundaries (countries, states/provinces, counties, etc . . there are a lot of maps out there which seek to define ecological boundaries, and they differ from group to group, and even the definitions of bio-region, ecosystems, ecotopes, etc. . . have changed with understanding. In a lot of ways, myself and others on here from North America, find the distribution of Native American/First Peoples languages informative. Initially Bio-regions where seen as drainage systems consisting of many watersheds. All of this information is useful to help you understand your-life place, how it is perceived by different groups. But, from there, get to know you life-place and its personality in regards to relationships with the people (human and otherwise) and how you relate to the life-place.
