Fish out of water series. Urbanite finds him/herself in Alaska against their will and ends up staying. Must adjust big city ways and learn to appreciate the local/folk culture. The similarities are obvious. -- and of course there's the Local A.M. Radio Talk Show who comments on much of the action.
On the differences side. Trees is a relationship show -- Sex in the Non-City. The lead character is also voluntarily trying to immerse herself in the culture, although her Big City ways are the main source of humor.
Overall NE and Trees are in a different league. So much more avant-garde humor on NE. Trees can get downright cheesey.
