A national treasure, this forest is a case study for conservation. There are three national parks in California that represent about 45% of the amount in the state. The trees are extremely tall and are up to 2,000 years old. Because they are located within a national park, there are 37 miles of coastline of the Pacific Ocean that are preserved and protected. This coastline has redwoods that run right up to it. Preserving this area was no easy task, as settlers in the 1800's often brought a saw and an axe to chop them down. By the 1900's, the forests were depleted and efforts were made to give the area a national park status to protect them.
