Humboldt Redwoods State Park

Humboldt Redwoods State Park. . , A World class Forest Preserve , Containing over 53,000-acres, Humboldt Redwoods State Park includes some of the world's most impressive redwood forests, many miles of river frontage, and nearly 100 miles of hiking, riding and mountain bike trails., Rockefeller Forest, west of the Dyerville and Founders' Grove area, is one of the largest remaining ancient redwood forests on earth. This majestic 10,000-acre forest is just a part of the 17,000-acres of old growth redwoods found in the park. Of the remaining coast redwoods, almost one in five are here., Measured as living and once-lived organic material, the Rockefeller Forest has over seven times the biomass as tropical rainforest. No other forest has more., The Visitor Center, 1.5 miles south of Weott, offers more information, exhibits, maps, and programs., Look Up! , To your left, a pole stands as an amazing measure of nature's power., The top, 33 feet above this street, indicates where waters crested during the 1964 flood, obliterating Weott's downtown., Memorial Groves , The signs you see throughout Humboldt Redwoods State Park identify groves honoring individuals or groups that made donations in order to protect these magnificent trees., Since 1918, the Save-the-Redwoods League has used private donations to purchase redwood lands from willing sellers. These donations are often matched by public park funds. These lands are then deeded to local, federal and state agencies such as California State Parks and turned into redwood parks and preserves. You can obtain more information about the Save-the-Redwoods League and the Memorial Grove Program at the Visitor Center., Poison Oak , Toxicodendron diversilobum , "Leaves of three, let them be!"
