The Myrtle Oak often grows as a shrub, but can also take the form of a tree. In maturity it grows to 15–20 feet (4.6–6.1 m) tall and 8–10 feet (2.4–3.0 m) wide. It is considered a red oak. [9] The leaves are simple alternate. [10] They appear dark green with a yellow-green underside. The leaves have a leathery texture, and an obovate ...
Chinquapin oak is usually a tree, but occasionally shrubby, while dwarf chinquapin oak is a low-growing, clone-forming shrub. The two species generally occur in different habitats: chinquapin oak is typically found on calcareous soils and rocky slopes, while dwarf chinquapin oak is usually found on acidic substrates , primarily sand or sandy ...
Oak regeneration failure is a woodland phenomenon whereby insufficient oak seedlings and saplings are recruited into the canopy to replace dead mature oaks.The result is a local decline in oak numbers while other more shade-tolerant trees such as maple, lime, and ash may become more prominent.
The species is unusual in that the lobes are not necessarily paired on opposite sides of the leaf, instead appearing alternate or sometimes haphazard in arrangement. The leaves are 18 to 25 cm (7 to 10 in) long and up to 18 cm wide. Leaves are dark green, smooth, and shiny on the surface; undersides are paler and pubescent. [3] The leaves and ...
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.
California black oak is a deciduous tree growing in mixed evergreen forests, oak woodlands, and coniferous forests. California black oak is distributed along foothills and lower mountains of California and western Oregon. [6] [7] It can be found at altitudes of up to 1,800 m (5,900 ft), for example near Mount Shasta. [4]
