Bioregions are real but cannot be bounded with hard lines

Evidence

As a scientific fact and simple matter of observation, there is no disputing that bioregions exist. If you go to the bioregion known as Cascadia (aka the Pacific Northwest), you are going to see Douglas fir and ponderosa pine, whereas if you go to the Southwest, you will not. But it’s impossible to draw a hard line around a bioregion. That’s because bioregions aren’t anything more than loose conglomerations of species that grow well together in certain conditions that necessarily vary geographically—a similar pattern to human language and culture. — Jenny Odell, How to Do Nothing, 503

Categorization

• DEFINE: Core definition of bioregion as ‘difference without boundary’ — a model of place and identity that avoids essentialism.
• XREF: The claim that bioregions mirror human language/culture resonates with the book’s broader attention-as-world-constitution thesis and Odell’s stated concern with ‘manifest dismantling’ vs. manifest destiny.
