the two concepts you stated aren't disparate (or, at least, without being in-depth they don't appear to be) but are part of the same theorectical framework. Yes, to deal with 'in the wild' you need to be able to thoroughly discuss what constitutes 'the wild' in your texts, both in terms of a physical environment and in terms of humanity. For example, if you were doing Wordsworth and Malouf ('An Imaginary Life'), you would discuss what each composer meant when he said 'wild' - eg. pastoral or desolation? - and how did humans interact with nature - eg. relationship of children and nature vs. adult and nature, religion in nature, cultivation/ownership vs. spiritual ownership etc. You also need to link everything you say back to context, both the composer's and the context of the text (eg, Malouf has a post-modern Australian context but his novel is set in Ancient Rome)
