Ah, I love this! The "rampage of nature" is a wonderful blend of Sam's good intentions and the violence that springs from the Ring.
(There's actually a scene very much like this in the Rankin-Bass cartoon Return of the King! For a brief scene, Sam contemplates taking the One Ring for himself and transforming all of Middle Earth into an idyllic garden, in a rather terrifying manner that looks very much like what I visualize in your ficlet. I've seen some people complain about that scene taking liberties with the text and Sam's character, but I always thought it was a really interesting view of how the Ring could potentially corrupt anyone, even him, however pure their ideals.)
