A list of tree species, grouped generally by biogeographic realm and specifically by bioregions, and shade tolerance. Shade-tolerant species are species that are able to thrive in the shade, and in the presence of natural competition by other plants. Shade-intolerant species require full sunlight and little or no competition.
In simple terms, shade-tolerant plants grow broader, thinner leaves to catch more sunlight relative to the cost of producing the leaf. Shade-tolerant plants are also usually adapted to make more use of soil nutrients than shade-intolerant plants. [2] A distinction may be made between "shade-tolerant" plants and "shade-loving" or sciophilous ...
Betula lenta (sweet birch, also known as black birch, cherry birch, mahogany birch, or spice birch) is a species of birch native to eastern North America. Description
[2] [9] They thrive in sunlight since they are a shade intolerant species, but eventually give way to longer lived, more shade tolerant species. In regenerative stands, Betula populifolia are commonly found along other early successional species such as paper birch, quaking aspen, and bigtooth aspen (Populus grandidentata). [3]
Betula lenta (sweet birch) [38] The wintergreen-scented wood, which turns dark when exposed to air, was traditionally used as a substitute for mahogany. It grows at a maximum altitude of 4,500 ft (1,400 m) in its southern range. Uses: timber; pulpwood, veneers. [39] OH, the Mid-Atlantic, New England and the Southeast —
Shade avoidance is a set of responses that plants display when they are subjected to the shade of another plant. It often includes elongation , altered flowering time, increased apical dominance and altered partitioning of resources.
In addition, the light weight of alder seeds – numbering 1.5 million per kilogram or 680,000 per pound – allows for easy dispersal by the wind. Although it outgrows coastal Douglas-fir for the first 25 years, it is very shade intolerant and seldom lives more than 100 years. Red alder is the Pacific Northwest's largest alder and the most ...
Betula nigra, the black birch, river birch or water birch, is a species of birch native to the Eastern United States from New Hampshire west to southern Minnesota, and south to northern Florida and west to Texas. It is one of the few heat-tolerant birches in a family of mostly cold-weather trees which do not thrive in USDA Zone 6 and up.
