Brände im Yellowstone-Nationalpark 1988

The Yellowstone Fire of 1988 was the largest forest fire known to affect Yellowstone National Park in recorded history. The fires burned for several months and by the time the winter snows extinguished the flames, 793,880 acres (321,271 ha) or roughly 36 percent of the park had been impacted by the fires. The fires were considered a disaster by many, especially in the years shortly after the fire had ended, but foresters and biologists have demonstrated that fire is a natural part of the ecosystem and many native plant and trees species are unable to properly reproduce without the assistance of fire. The fires burned in what is known as a "mosaic pattern"; leaping from one area to another and leaving huge expanses of forestland completely untouched in between areas that were burned. After almost 20 years, much of the areas that burned have started to rejuvenate, and in many cases, is healthier, denser and more disease resistant.
