Trees

Okay New topic and it’s all about trees

okay many trees or all of the trees are helpful to our environment trees can be found everywhere

but mostly trees can be found in Forest, plant community, predominantly of trees or other woody vegetation, occupying an extensive area of land. In its natural state, a forest remains in a relatively fixed, self-regulated condition over a long period of time. Climate, soil, and the topography of the region determine the characteristic trees of a forest. In local environments, dominant species of trees are characteristically associated with certain shrubs and herbs. The type of vegetation on the forest floor is influenced by the larger and taller plants, but because low vegetation affects the organic composition of the soil, the influence is reciprocal. Disturbances such as a forest fire or timber harvesting may result in a shift to another forest type . Left undisturbed, ecological succession will eventually result in a climax forest community. Human intervention is practiced to maintain some desirable forest types.one of these is Redwood National Park, which covers 455 sq km (176 sq mi) along California’s northwestern coast, represents one of the last remaining ancient redwood forests in the world. Here, heavy coastal rainfall and lack of exploitation by humans has encouraged the dramatic growth of some of the largest trees on earth. Some of these redwoods are believed to be more than 2,300 years old.

now let me tell you about the Role of the Forest:

Forests provide habitat for a wide variety of plants and animals and perform many other important functions that affect humans. Photosynthesis is the chemical process in the leaves that uses sunlight and carbon dioxide to produce energy-supplying sugars for the tree or plant—in the process the foliage of the plants and trees gives off pure oxygen for breathing. Forests also prevent erosion, the wearing away of soil by wind and rain. In bare lanscapes with little or no vegetation, heavy rains fall uniformly over large areas and can wash soil into rivers and streams and cause landslides and flooding. This leads to ecosystems that are deprived of both water and soil, which are quickly carried away in rivers and streams. In forested areas the forest canopy (treetops) intercepts and gradually re-distributes precipitation that would otherwise cause this flooding and erosion—some of the precipitation flows down the bark of the trunks as stemflow, the rest percolates through the branches and foliage as throughfall. This slower and nonuniform distribution of the rain ensures that soil and water will not be immediately carried away. In addition, the roots of the trees and other vegetation hold the soil in place and prevent flooding and clouding of streams and rivers. Forests also increase the ability of the land to capture and store valuable water. The canopy is especially efficient at capturing water from fog—condensed, cloudlike water vapor—which it distributes, like precipitation, into the vegetation and soil. Water stored in tree roots, trunks, stems, and foliage, as well as the soil of the forest floor, enables forests to maintain an even flow of water in rivers and streams in times of heavy precipitation or drought.

now that the role of trees….. Thank you for Viewing!!!!
