The Changa Manga (Urdu, Punjabi: چھانگا مانگا) is a planted forest which includes a wildlife preserve, in the Kasur and Lahore districts of Punjab, Pakistan. It is located approximately 80 kilometers south-west of Lahore. It was once the largest man-made forest in the world but has undergone illegal deforestation at a massive scale in recent times. Named after two brother dacoits, the Changa Manga forest was originally planted in 1866 by British foresters. Its trees were harvested to gather fuel and resources for the engines employed in the North-Western railway networks.
