The ability of trees to graft is occasionally exploited by tree shaping to create living root bridges in Meghalaya and Nagaland states in India and on the islands of Sumatra and Java in Indonesia. The aerial roots of rubber fig trees, Ficus elastica , are used to form suspension bridges across mountain streams.
Understory is made up of bushes, shrubs, and young trees that are adapted to living in the shade of the canopy. Canopy is formed by the mass of intertwined branches, twigs, and leaves of mature trees. The crowns of the dominant trees receive most of the sunlight. This is the most productive part of the trees, where maximum food is produced.
Forestry is an important economic segment in various industrial countries, [7] as forests provide more than 86 million green jobs and support the livelihoods of many more people. [6] For example, in Germany, forests cover nearly a third of the land area, [ 8 ] wood is the most important renewable resource , and forestry supports more than a ...
An evergreen forest is a forest made up of evergreen trees. They occur across a wide range of climatic zones, and include trees such as conifers and holly in cold climates, eucalyptus, live oak, acacias, magnolia, and banksia in more temperate zones, and rainforest trees in tropical zones.
Forest ecology shares characteristics and methodological approaches with other areas of terrestrial plant ecology, however, the presence of trees makes forest ecosystems and their study unique in numerous ways due to the potential for a wide variety of forest structures created by the uniquely large size and height of trees compared with other ...

Sperry said, “If a pecan tree is free-standing, that is, not touching other trees, power lines, etc., you can put a sheet metal collar in place around its trunk.”
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.
