Some, Hughes among them, would say that nature poems should show us something about ourselves. Others would say that precise description is enough.
When I look at a well crafted wildlife photograph with light, focus and composition showing the creature in stunning detail, being itself in its habitat - that's all you need, isn't it? So why shouldn't poetry be the same? After all, isn't wildlife there for its own sake? It seems to manage very well in those areas that are most remote to humans.
Is admiration sufficient response? What do you think?
