ʻŌhiʻa trees grow easily on lava, and are usually the first plants to grow on new lava flows. Metrosideros polymorpha is commonly called a lehua tree, or an ʻōhiʻa lehua , or simply an ʻōhiʻa ; all are correct, [ 6 ] although ʻōhiʻa is also used to refer to the tomato as well as certain varieties of sugarcane and taro .

Deforestation or forest clearance is the removal and destruction of a forest or stand of trees from land that is then converted to non-forest use. [1] Deforestation can involve conversion of forest land to farms, ranches, or urban use. About 31% of Earth's land surface is covered by forests at present. [2]
Old-growth forests tend to have large trees and standing dead trees, multilayered canopies with gaps that result from the deaths of individual trees, and coarse woody debris on the forest floor. [8] The trees of old-growth forests develop distinctive attributes not seen in younger trees, such as more complex structures and deeply fissured bark ...
Wet sclerophyll forest with the dominant tree species being the mountain ash, Eucalyptus regnans, the tallest flowering plant in the world. The forest has recovered well from logging that occurred from the mid-19th century until 1930. Sherbrooke Forest is famous for its population of superb lyrebirds.

Giant sequoia. Silvics of North America (1991), [1] a forest inventory compiled and published by the United States Forest Service, includes many conifers. [a] It superseded Silvics of Forest Trees of the United States (1965), which was the first extensive American tree inventory. [3]
A pine forest is an example of a temperate coniferous forest Forest communities dominated by huge trees (e.g., giant sequoia, Sequoiadendron gigantea ; redwood, Sequoia sempervirens ), unusual ecological phenomena, occur in western North America, southwestern South America, as well as in the Australasian region in such areas as southeastern ...
The canopy at the Forest Research Institute Malaysia showing crown shyness. The canopy layer contains the majority of the largest trees, typically 30 metres (98 ft) to 45 metres (148 ft) tall. The densest areas of biodiversity are found in the forest canopy, a more or less continuous cover of foliage formed by adjacent treetops. The canopy, by ...
A tree here may grow over 23 m (75 ft) in height in just 5 years. From above, the forest appears as an unending sea of green, broken only by occasional, taller "emergent" trees. These towering emergents are the realm of hornbills, toucans, and the harpy eagle. [1] Generally, biodiversity is highest in the forest canopy
