Forests are a terrain feature which can be found on tundra, plains and grassland hexes. They can and often will share their tile with hills, and the defensive bonuses from both features will stack. If cut down by a worker, forests will provide a lump sum of production points to the nearest city of the worker's civilization, but will destroy the forest forever. Lumbermills, camps and trading posts can be constructed in forests without cutting them down, but ordering any other tile improvements will cause them to be removed (still providing the one-time production boost).
For early man, the forests were a great source of bounty, providing wood for fire, tools and shelter, and also many animals for sustenance and clothing. As a city grows there is a great temptation to cut down the forests for farmland, but a wise leader will always leave some standing - for productivity and to lift his people's spirits. Also, military units stationed in forests receive a significant defensive bonus.
