The probability of growing trees is something complicated in the game. Trees do grow only on specific terrains. This page should help you to make appropriate decisions to put which tree on which terrain in the editor.

Biomes and trees

There are 4 biomes in widelands which represents climate zones. Each of this biomes has terrains where trees grow well and terrains where trees wouldn't grow. A climate zone has mostly specific trees that will grow there. For example most palm trees would grow only on terrains of desert biome. So for each biome there are some trees that do only grow on some terrains of this biome. But some trees do also grow on terrains of other biomes. For example beech, being the most drought-resistant of the summer trees, will grow in some desert and wastland terrains.

Below are estimations for how well trees grow on each terrain. as the current algorithm doesn't allow precise calculation, those values are often approximate, and there is a bit of uncertainty on them. All terrains not included in the list will not grow trees.
