nature art

After reading Morton's Ecology without Nature, I've been thinking about the intersections between nature and art - how does art attempt to represent nature? Artists as ecocritics, Art is unnatural? Art calls attention to its own form - when you call something "art," you immediately invite some sort of reflection on that object.... Some of these ideas are mine, and some are from the essay. Mostly I'm just confused. So I went and looked at a page I bookmarked a while ago - this artist, Nina Katchadourian, plays with maps, images, found objects, nature - and comes up with some thought provoking images (even if they were created with the intent to display them in a gallery) -

This grouping is titled "Transplant" -
