Thanks Torq :-)
Well the green area is supposed to repressent a steppe area. A wide area of open ground, fertile soil and a lot of grass. Like the one you today have in ukrain. I'd probably remove the western green area and will only keep the one that goes down to you. If that type of area doesn't fit in to your region just tell me and I let it quit a bit further north.
And by the way the steppe is called "the green sea"
