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 ...
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.
Ecology (from Ancient Greek οἶκος (oîkos) ' house ' and -λογία ' study of ') is the natural science of the relationships among living organisms and their environment. Ecology considers organisms at the individual, population , community , ecosystem , and biosphere levels.
Ecosystem ecology is the "study of the interactions between organisms and their environment as an integrated system". [2]: 458 The size of ecosystems can range up to ten orders of magnitude, from the surface layers of rocks to the surface of the planet. [4]: 6
With the rise of ecology and environmental science, there has been a reordering in the applied sciences. In line with this view, forestry is a primary land-use science comparable with agriculture. [10] Under these headings, the fundamentals behind the management of natural forests comes by way of natural ecology.
Dead trees pose a safety risk, especially during high winds and severe storms, and removing dead trees involves a financial burden, whereas the presence of healthy trees can clean the air, increase property values, and reduce the temperature of the built environment and thereby reduce building cooling costs.
Understory reinitiation: Trees die from low-level mortality, such as windthrow and diseases. Individual canopy gaps start to appear and more light can reach the forest floor. Hence, shade-tolerant species can establish in the understory. Old-growth: Main canopy trees become older and more of them die, creating even more gaps.
They can be about 45 metres high. The trees (and sometimes shrubs) are of various heights. One tree has its crown at the height of another’s trunk. At the top the crowns of the different species of trees form a more or less closed canopy. This layer creates special ecological conditions in the underlying layers of forests. The density of the ...
