1) Feral forests (Planted tree zones, for instance along motorways, that have been allowed to become wild to the point that their wildness is outgrowing their manmadeness.)
2) In limbo forests (Tree-covered plots that feel like forests but technically probably aren't; states of vegetation for which lay-language has no name.)
3) Incognito Forests (Forests that have gone cryptic and are almost invisible, forests in camouflage, forests with a talent for being ignored.)
4) Precognitive forests (Lands that are on the brink of becoming forested, a future forest fata morgana.)
5) Unappreciated forests (Forests regarded as zones of waste and weed, forests shaming planners, developers, and the neighbourhood. NIMBY forestry.)
