Several people have asked me to recommend books on "Nature Writing" for them to read. That started me thinking about what Nature Writing was and how I might categorize it. I soon gave up the task. There are too many ways to slice that cake. I finally decided to simply list the books that I remembered having read and then try to see what they had in common. I'm sure there are books that I have forgotten, but the list is long enough and I'm going to leave it as it is.
