The Redwood National and State Park comprises ancient temperate rainforest trees that are located in the United States. Where more than 2,00,000 acres of redwood trees covered the Californian coastline in 1850, by the 1900 many trees had been harvested and cut people who were attracted to the lands during a minor gold rush. With many threatened varieties of trees existing in the forest, as also to conserve the area, the efforts were taken to preserve the trees. The resultant National Park now protects not only indigenous flora and fauna but also the grassland prairie and parts of rivers and streams.
