Terrain: deforestation and regrowth skill

Skill 'deforestation'.

• This is a passive skill, it works automatically.

Trees in forested terrain can be destroyed -- for example, with an axe, a hurricane, or fire. Destroyed trees will eventually grow back, but you will have to wait a very long time. You can speed up the process by watering the soil or fertilizing it with ash.

Slightly damaged trees (for instance, notched) will heal their wounds in time, while heavily notched ones will dry out and snap.
