Quercus robur is a deciduous tree up to 40 metres (130 ft) tall, [5] with a single stout trunk that can be as much as 11 m (36 ft) in girth (circumference at breast height) or even 14 m (46 ft) in pollarded specimens. Older trees tend to be pollarded, with boles (the main trunk) 2–3 m (6 + 1 ⁄ 2 –10 ft) long. These live longer and become ...
The 90-foot-tall willow oak, which towers over the street on the south edge of Nash Square in Raleigh, was cut down on Thursday, Oct. 10, 2019, due to old age and disease.
Many of the killed trees sprout and form a new stand. However, the economic loss may be large unless at least some of it can be salvaged. Oak wilt (Bretziella fagacearum) is a potentially serious vascular disease of black oak that is widespread throughout the eastern United States. Trees die within a few weeks after the symptoms first appear.
Quercus macrocarpa is a large deciduous tree growing up to 30 metres (98 feet), rarely 50 m (160 ft), in height, [3] and is one of the most massive oaks with a trunk diameter of up to 3 m (10 ft).
The tree measured 8 m (25 ft) in circumference at the base and 5 m (16 ft) in circumference 1.2 m (4 ft) above the ground. The tree was 23 m (75 ft) tall, and its branches spread over 38 m (125 ft) from tip to tip. [10] The oak, claimed to be the oldest in the United States, began showing signs of poor health in the mid-2010s. [11]
Live oak was widely used in early American butt shipbuilding.Because of the trees' short height and low-hanging branches, lumber from live oaks was used in curved parts of the frame, such as knee braces (single-piece, L-shaped braces that spring inward from the side and support the deck), in which the grain runs perpendicular to structural stress, making for exceptional strength.
Oak seeds are faster-growing than many other trees and can compete very successfully. To regenerate oaks, the oak saplings should be 4–5 feet tall before removing the overstory. To favor oak regeneration, non-oak stems in the understory exceeding 4 feet can be controlled by various methods. The quality of the environment impacts oak regeneration.
The tree has a girth of 14.02 metres (46.0 ft) measured at 1.5 metres (4 ft 11 in) off the ground, making it the UK's largest and widest tree since the collapse of the Newland Oak in Gloucestershire, [1] [2] [3] surpassing trees such as the Bowthorpe Oak in Lincolnshire and the three large sweet chestnut trees at Canford School, Dorset.
