The coast redwood is a prodigious sprouter. March 15-17, 2004, Rohnert Park, CA. Redwood seedlings are also very vulnerable to infection by damping off fungi (Botrytis) during their first year. Temperatures average 50 - 60° degrees Fahrenheit with the minimum being 10° on the coast and 30° on the eastern edge. Temperatures are moderate year round, with mild wet winters, and dry summers. Dawn Redwoods are a smaller relative of the Coast Redwoods. Heart rots including brown cubical rot (Poria sequoiae) and white ring rot (Poria albipellucida) can cause extensive cull. On industrial land, clearcutting is the preferred silvicultural system. Redwood has no taproot but its roots spread out over large areas. In August 2020, stands of the trees were burned in various wildfires in northern and central California, including a famous grove of old-growth trees in Big Basin State Park. Although several species are commonly ascribed the name redwood, it really only belongs to one: the coast redwood (Sequoia sempervirens). Shelterwood, and selection cut are also used, though both are considered less economical because residual trees may be toppled by wind or damaged during logging, or may not grow well. Does the Shamel Ash Tree Lose Its Leaves? This species grows fast – at a rate of around 2 feet per year! Small trees in the deep shade of the forest floor can survive for many years and then grow vigorously when events around them, such as logging or fire, increase the sunlight they receive. Pure stands of redwood are found only on the best sites; moist flat ground along rivers with gentle slope below 1,000 feet in elevation. Conifers. In the extreme southern portion of its range coast redwood is found in narrow canyons bottoms near ocean. Sprouts develop their own root system and create circles of new trees around old stumps. Redwood predominate in these locations because it is better adapted to flooding than other trees. The coast redwood, also called the California redwood, is the tallest living thing in the world. The tallest on record is around 140 feet. Redwoods are also suitable as screens planted 15 to 20 feet apart. Redwood is shade tolerant, meaning that it can survive at very low light levels. Redwood is often found growing with Douglas-fir which can grow as quickly as redwood on many sites. Sarah Moore has been a writer, editor and blogger since 2006. Through the northern parts of its range coast redwood can be found on all slopes, in the southern portion of its range it can be found on western and northern slopes. Although many redwood stands are close to the sea, they do not seem to tolerate ocean winds or salts and so do not grow on exposed hillsides that face the ocean. Both coast redwood and Sierra redwood grow at a moderate rate, which means they gain between 12 and 24 inches of height in a single growing season. United States Forest Service: Coast Redwood, North Carolina State Univeristy: Sierra Redwood, Oregon State University: Redwood (Sequoia). girdles stems and branches, and can be especially harmful in plantations. Old growth redwoods occupy about 200,000 acres, most of which is in state and national parks. All have a moderate drought tolerance, but they've evolved in areas where moisture is not usually a problem, so they like moisture as well as good drainage. On drier slopes tan oak, madrone, maple, and California bay laurel grow along with the conifers. Fog actually condenses on tree crowns and drips down to water the roots of the tree during the dry summer months. One of the reasons coast redwoods are a highly desired timber species is because they grow so quickly in forests managed for harvest. On flat ground near streams redwood reach its maximum growth rates and size. Mean annual increments over 30 cubic metres per hectare a year are achievable. The Sierra redwood, on the other hand, usually only reaches 60 feet or so in the garden, though true to its name the “giant sequoia” can reach heights of 300 feet in the wild. © Copyright 2020 Hearst Communications, Inc. Coast redwood usually dominates when growing with other trees. It took more than a century for 285-year-old tree 13 in the city of Arcata to recover from damage inflicted during the city’s construction. Redwoods generally do not need pruning in order to develop strong structures. Cones are about an inch long, hard and woody, made up of thick, wrinkled scales. Proceedings of the Coast Redwood Science Symposium—2016 September 13–16, 2016 Sequoia Conference Center, Eureka, CA. Some even live to be thousands of years old. Redwood's tolerance and ability to sprout allow great latitude in the choice of silvicultural system. Seeds are shed after cones open in the fall. Growth rings one half inch … Both coast and dawn redwoods can handle occasionally wet soil. Redwood growth depends on the soil moisture available during the course of the year. It is one of only a few species classified as a deciduous conifer. Redwoods grow when minimum soil moisture ranges from 18 to 86%, but they grow best when soil moisture does not go below 60 %. Dawn redwood vs. Bald Cypress. Redwood seedlings require greater soil moisture than most associated trees because they do not have root hairs. All three trees prefer full sun, which may help explain their great heights that help them outcompete other trees for light. Other damaging agents are branch canker, and heart rots. Proceedings of Conference on Coast Redwood Forest Ecology and Management, June 18-20, 1996. Redwood is named for the color of its bark and heartwood. While the maximum height is only 90 feet, the Dawn Redwood is easier to care for than the Coast Redwood. Grand fir and western hemlock from northern Sonoma county north. Over a hundred sprouts may arise from the stump of one cut tree. Although some individuals were lost, most were expected to survive, owing to their ability to withstand fire. Coast redwoods are exceptionally fire-adapted. Even stepping on the soil above the shallow root system could be enough to break the roots and kill the tree. While the coast redwood grows at a medium rate, as does the Sierra redwood, the dawn redwood grows quite quickly. This strip is 5 to 35 miles wide and covers approximately 2.2 million acres. Sequoia sempervirens 'Aptos Blue' is a strong and fast growing selection of Coast redwood with horizontal branching and pendant branchlets holding dark Blue-green foliage. Seeds are small and light and fall up to 200 feet uphill and 400 feet downhill under average conditions. Coast redwood can be found at elevations ranging from sea level to 3,000 feet. Dawn Redwood (Metasequoia) – Finally there is the Dawn Redwood which is the “smallest” of them all that can reach over 100 feet tall. The high tannin content of the wood gives the trees remarkable resistance to fungus, diseases, and insect infestations, reasons why redwood lumber is so desirable.
