Trees

Trees are the only resource of wood. They're usually growing on a map. If not there should be at least some tree seeds that can be planted, irrigated and harvested eventually. Trees can spread automatically if left for seeding. The seeds then can either remain on the ground close to the tree or plant themselves and start growing as a brand new tree. If you want to prevent trees from spreading at certain are, build either paths or fences around these trees. Trees can burn down during fire cause by lightning. It's good to build sprinklers, water cannons or at leat lightning conductors close to a forest. Trees can also dry up and die if they don't have enough of moisture in the ground. In the game are 4 different kinds of trees with different moisture requirements:

• Spruce - min 10% mositure
• Willow - min 40% mositure
• Birch - min 5% mositure
• Linden- min 20% mositure
