where does the redwood forest start and end
Redwood National and State Parks The Redwood National and State Parks (RNSP) are old-growth temperate rainforests located in the United States, along the coast of northern California. Comprising Redwood National Park (established 1968) and California's Del Norte Coast, Jedediah Smith, and Prairie Creek Redwoods State Parks (dating from the 1920s), the combined RNSP contain 139,000 acres (560 km2).[3] Located entirely within Del Norte and Humboldt Counties, the four parks, together, protect 45% of all remaining coast redwood (Sequoia sempervirens) old-growth forests, totaling at least 38,982 acres (157.75 km2). These trees are the tallest and one of the most massive tree species on Earth. In addition to the redwood forests, the parks preserve other indigenous flora, fauna, grassland prairie, cultural resources, portions of rivers and other streams, and 37 miles (60 km) of pristine coastline.
Temperate deciduous forest The principal factor operating in these forests is the seasonal appearance and disappearance of the canopy.[6] Shade from the canopy limits the growth of many kinds of plants. Many species that are typical of these forests time their growth and flowering to the short period just before the canopy opens; hence, they are known as spring ephemerals. Examples include trilliums and bloodroot. Most spring ephemerals are insect-pollinated, and the seeds themselves are often transported by ants,[7] a mode of dispersal known as myrmecochory. A smaller number of species is able to grow under the canopy, and even a few that grow during the period when leaves are being lost. The average yearly precipitation is 30 - 60 in (75 – 150 cm). Temperate deciduous forests have a great variety of plant species. Most have three levels of plants. Lichen, moss, ferns, wildflowers, and other small plants can be found on the forest floor the shrubs fill in the middle level, and hardwood trees like maple, oak, birch, magnolia, sweet gum, and beech make up the third level. Birds such as broad-winged hawks, cardinals, snowy owls, and pileated woodpeckers are also found in this biome. Mammals include white-tailed deer, raccoons, opossums, porcupines, and red foxes. Animals that live in the temperate deciduous forest must be able to adapt to the changing seasons.
