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.
The cones are smaller, 5–12 cm (2.0–4.7 in), the wood is denser, and the tree has a thicker taproot. [9] Unlike the typical variety of slash pine, seedlings of P. e. var. densa has a "grass stage" similar to longleaf pine. P. e. var. densa is not frost tolerant, which limits its range to South Florida. [12]
In parts of Africa, Asia and Australia, the species has become a harmful invasive species. The top of the plant is hardy to zone 8 but it is root hardy to zone 7. [8] Drought tolerant, the species grows best in occasionally moist, humus-rich, well-drained soil in full sun or partial shade.
It is a small to medium-sized deciduous tree, reaching 6–23 metres (20–75 feet) tall, often with a canopy spread of 6 m (20 ft). Its habit varies based on the level of sunlight; in full sun it will have a short trunk with a crown as wide as it is tall, while under a canopy it will have a tapered trunk with a short, slender crown.

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 10-year-old tree is typically about 5 m (20 ft) tall. As with most trees, forest-grown sugar maples form a much taller trunk and narrower canopy than open-growth ones. [citation needed] The leaves are deciduous, up to 20 cm (7.9 in) long and wide, [8] palmate, with five lobes and borne in opposite pairs. The basal lobes are relatively small ...
Depending on subspecies, Pinus contorta grows as an evergreen shrub or tree. The shrub form is krummholz and is approximately 1 to 3 meters (3 to 10 ft) high. The thin and narrow-crowned tree can grow 40 to 50 m (130 to 160 ft) high and achieve up to 2 m (7 ft) in diameter at chest height. [4] The murrayana subspecies is the tallest.
Acer leucoderme (English: chalk maple; also whitebark maple, pale-bark maple and sugar maple [2]) is a deciduous tree native to the southeastern United States from North Carolina south to northwest Florida and west to eastern Texas. It lives in the understory in moist, rocky soils on river banks, ravines, woods, and cliffs.
