When you think of it, with Gridanians as representatives of the Elementals the forest has it's own defence and diplomacy with other nations. If it weren't for Gridanians the forest will slowly lose ground as more and more people start hunting and logging. While strong, they aren't all-powerful.
Whose to say that Ul'dahs thaumaturge and alchemist can find a way to greatly weaken/poison the forest and thus elementals. With airships they can do air raids.
Without gridanians the forest is unclaimed territory, albeit with dangerous creatures inhabiting it.
