Hey all!

I'm looking to do a bit of MMPing on my city tiles. I currently have a varied region of streams, hills, plains,coastlines and mountains, and am using Girafes trees. I've seen some rather colourful work as of late and am looking to impliment deciduous trees into my cities. Does anyone have any rough guides as when deciduous trees should be used and evergreen used instead? ie. on what types of landscapes?
