Permanently removed by the construction of any tile improvement except a Trading Post, Camp, or Brazilwood Camp on its tile. Unlike a forest, does not provide a one-time Production bonus to the closest city when cut down.
Jungles can provide a wide array of bonuses, so if you manage to get your hands on the Sacred Path Pantheon belief, you might not want to cut your jungles down. Combined with the benefits of a University and thanks to the fact that you can build Trading Posts in jungles, you can turn your jungle tiles into powerhouses which each accumulate vast amounts of Science, Gold, Culture and Food in the early stages of the game. Moreover, the +25% defensive bonus will allow you to defend your empire with fewer units, letting you focus your attention (and production) on other things. On top of that, if your empire is covered in jungle, the movement cost of 2 essentially provides a slightly watered down version of the effects of a Great Wall without having to build it, making invasions especially cumbersome for potential enemies. Therefore, cities surrounded by jungle are actually ideal for empires going for a scientific or cultural victory.
Dark, forbidding, and deadly to the uninitiated, jungles are a rich source of food to those with the skill and knowledge to live within them. However, jungles do not provide much in the way of materials, and a growing civilization may be tempted to mine them or turn them into cropland. However, military units situated in jungles receive a significant defensive bonus.
