A CHECKLIST OF THE VASCULAR PLANTS OF THE REDWOOD NATIONAL & STATE PARKS James P. Smith, Jr. Professor Emeritus of Botany Department of Biological Sciences Humboldt State Univerity Arcata, California 14 September 2018 The Redwood National and State Parks are located in Del Norte and Humboldt counties in coastal northwestern California. The national park was F E R N S established in 1968. In 1994, a cooperative agreement with the California Department of Parks and Recreation added Del Norte Coast, Prairie Creek, Athyriaceae – Lady Fern Family and Jedediah Smith Redwoods state parks to form a single administrative Athyrium filix-femina var. cyclosporum • northwestern lady fern unit. Together they comprise about 133,000 acres (540 km2), including 37 miles of coast line. Almost half of the remaining old growth redwood forests Blechnaceae – Deer Fern Family are protected in these four parks. They are recognized as a World Heritage Struthiopteris spicant • deer fern Site and an International Biosphere Reserve. Woodwardia fimbriata • giant chain fern Of course, the best known member of the flora here is the coast redwood Cystopteridaceae – Brittle Fern Family (Sequoia sempervirens). The largest groves are in the state parks. The tallest Cystopteris fragilis • brittle bladder fern redwood, named Hyperion, is 379.1 ft (115.55 m) tall. It is the tallest living tree in the world and is located in the national park. Hyperion is estimated to Dennstaedtiaceae – Bracken Fern Family be 700–800 years old.
