Muir Wood National Monument is best known for its Coast Redwood, a relative of the Giant Sequoia. Redwoods can grow to as tall as 380 feet and at the tallest at Muir Woods is 258 feet. It is such a wonder how a tree this tall could have come from a seed no bigger than that of a tomato. The average age of a Redwood in Muir Woods is between 500 to 800 years old and the oldest tree at the park is said to be 1,200 years old!
Aside from the Redwoods that thrive in Muir Woods, there are other tree species that has greatly adapted to the scarce sunlight due to the height of the Redwoods. Prominent among these are the California Bay Leaf, Big Leaf Maple and the Tanoak.
As part of the Muir Woods thrust of preserving the natural ecology of the park against industrialization and urban encroachment, it has also recognized the importance of not only taking into consideration the landscapes, wildlife and cultural resources. They have also taken steps to preserve the natural sound of the forest. At the park’s Cathedral Grove where some of oldest and tallest trees can be found, signs were placed to remind visitors to keep the silence and to turn off their mobile phones while inside the grove.
