The language or nationality is not the main problem here.
As Åland is an autonomous region, we can say Country, it has different local laws and regulations than in Finland (!) (or Sweden) for natural reserves, recreation areas, camping, hunting etc.
So there is no real question if Åland needs very own reviewer as the reviewers need to understand the issues in legislation, environmental protection and so on. Åland should have own reviewer as the foreign ones just cannot have clear knowledge about the specialities of the Islands.
But as we have noticed so many times before the nature preservation is not the first or even second on line in geocaching "community" business.
