This map is based on terrain from the area around Dungarvan in southern Ireland, with some additional islands that don't exist in reality. Three inlets of differing lengths create breaks in the terrain which are good for castle defense. A series of high hills divides the main land area into separate valleys. There is a large island with an excellent harbour.
Lowland forests provide hunting while the uplands are barren and unable to grow crops. Check the fertility map overlay to see where you can grow crops. The best cropland is covered in woodland and will have to be cleared for farms. Trees can be planted on the uplands but not farm crops.
For more variety I added shrubs and saplings that yield 1 wood, compared to 2 wood for normal trees.
Stone is scattered over large areas rather than concentrated in the normal infinite deposits. After mining, each stone is removed from the map (stones contain between 8 and 16 stone each). You will need to continually take in new stone areas to keep a steady supply, until you find a stone quarry through prospecting. Stone quarries have an infinite supply.
Berries are not clustered, but scattered amongst other bushes. Berry bushes have red or blue berries.
All the new plants can be planted by the forester (allowing large berry farms).
