Best wordsworth poems to relate to naturalism

I'm typing an essay on Wordsworth, and was going to include

part II of the Lucy poem
and
i wandered lonely as a cloud

to speak of naturalism. are there any better poems, in you opinion, that could possibly show naturalism in a more profound way?

thanks so much

- the gist of the essay is naturalism being a poetic device in which readers are more fully able to relate to a poem and let it affect their hearts and emotions, thus walking away from the poem with a sense of enlightenment.
