Legal Question in Environmental Law in California

I was not familiar with the term, but if nothing else, there's always Wikipedia, at http://en.wikipedia.org/wiki/Inholding . The first paragraph says it all: If one was a private owner of land before it was designated a national park/forest, then the held real property (i.e. the "inholding") is grandfathered as privately held within the national partk/forest. There's also an article about this issue at http://www.wilderness.net/library/documents/Tanner1.pdf .
