aka: Sovereign Land.
Some areas of the Pokémon World are left for Pokémon to inhabit, colonize and organize independently, outside of overall human interference. Among those, the ones that have evolved into cross-species societies of their own take the form of Sovereign Lands or Sovereignties: areas governed by Pokémon and structured for their own use.
From a sociological perspective and since Pokémon are sapient species, a Sovereignty has similar standing to a human-maintained “region” or smaller distinction of such as a district, including having its own form of government. At the geopolitical scale, most Sovereignties would likely be equivalent to human communes or districts and be treated as such where borders, supplies and trade are concerned, whereas some of the larger or more powerful Sovereignties could have political weight equivalent to that of a human province - and some of them would be considered independent territories and have embassy representatives, probably in the form of Ranger-class Trainers.
Bottom line: in this world humans do take into consideration they are not the only sapient species.
