Giant Redwoods Attacked by Tiny Fungus
News story originally written on September 17, 2002
Redwood trees are the tallest trees in the world. They grow in Northern California and can live for as long as 2000 years. Today, a deadly fungus threatens these trees.
Both the redwood trees and some Douglas fir trees in California have become infected with the fungus, which has killed more than 10,000 oak trees in the past three years. The disease does not seem to kill the old trees but it can kill the young trees.
The redwoods and the Douglas fir trees are very important. As the biggest plants, they control what the forest ecosystem is like.
