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 ...
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.
Tamarack is very intolerant of shade. [8] Although it can tolerate some shade during the first several years, it must become dominant to survive. [8] When mixed with other species, it must be in the over story. [5] The tree is a good self-pruner, and boles of 25- to 30-year-old trees may be clear for one-half or two-thirds their length.

Shade-intolerant species such as trembling aspen (Populus tremuloides) and marsh reedgrass (Calamagrostis canadensis) will thrive in the open conditions of a clearcut, outcompeting shade-tolerant species such as white spruce (Picea glauca). Mechanical site preparation and herbicide treatments are often applied initially to allow for adequate ...
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.
After a stand-replacing disturbance, shade-intolerant species colonize and grow into a dominant canopy, but due to their shade-intolerance they are unable to regenerate under their own canopy; the understory (composed of shade-tolerant species) gradually replaces the canopy, and due to its shade-tolerance it can regenerate under its own canopy ...
Liriodendron tulipifera is generally considered to be a shade-intolerant species that is most commonly associated with the first century of forest succession. In Appalachian forests, it is a dominant species during the 50–150 years of succession, but is absent or rare in stands of trees 500 years or older.
Western larch grows more quickly than many associated trees, as it needs to because larch is shade intolerant. With its thick bark, nonflammable foliage and protective cones, the species is very fire resistant. [5]
