![]() The Story of the Discovery and Naming of Dawn RedwoodĬorvallis: tree in Riverfront Park, just south of the Harrison Ave.Metasequoia flourished in the Miocene epoch of 25 to 5 million years ago and left its record embedded in rocks across the Oregon landscape. State Fossil of Oregon: The Oregon legislature designated the Metasequoia as the official state fossil in 2005. 'Miss Grace' - more or less ground sprawling, but if staked, a small tree with weeping branches.'Gold Rush' - bright yellow foliage in spring and retains much of the color throughout the summer.The tree is a tourist attraction in its own right and is now protected by an ornate fence. Several cultivars are available, including: Metasequoia glyptostroboides growing in Moudao village, Hubei, China. Hardy to USDA Zone 4 Native to Sichuan (Szechuan, Szechwan), China. Easy to transplant, performs best in moist, well-drained, slightly acid soils. Pollination occurs in early spring and the seeds in the female cones are mature by the fall. (However, because of western Oregon's wet, but mild, winters, the cones are not dry enough to open and release the seeds until the following spring.) ![]() The female (seed) cones are solitary, oval, green then light brown, about 2 cm long male (pollen) cones are arranged in long pendant clusters, each cone is globose and about 5 mm long. Given that the sample plot has a fence outside and M. This species is distinguished by its well-developed terminal buds and distinct central trunk morphology. Bark reddish brown when young, darker, fissuring, and exfoliating in strips when mature. The trees are monoecious, both male and female cones on an individual plant. This paper proposes an improved YOLOv7 model designed to precisely extract the crown width of Metasequoia glyptostroboides. Needles are arranged in opposite pairs, each is about 15 mm long, straight or slightly curved, bright green above, light green below. Corvallis: tree in Riverfront Park, just south of the Harrison Ave. Deciduous conifer, 70-100 ft (21-30 m), excurrent, pyramidal, flat topped when mature. Metasequoia flourished in the Miocene epoch of 25 to 5 million years ago and left its record embedded in rocks across the Oregon landscape.
