Benefits of Forests “As Suplyer Oxygen is The Main Raw Material for Human Respiratory”

Greening is one of the important activities that must be carried out conceptually in addressing the environmental crisis. So important that greening is a national program implemented throughout Indonesia.

 Once the importance of the role of plants on earth in addressing the environmental crisis, especially in urban areas, is appropriate if the existence of the plant to get serious attention in the implementation of urban greening as an element of the urban forest.

 Greening the role and function (1) As the lungs of the city. Plants as green elements, the growth yield of acid (O2) that is necessary for living things to breath, (2) As a control environment (micro), the vegetation will cause local environmental air becomes cool, comfortable and fresh, (3) the Creator of the environment life (ecological), (4) Balancing nature (adaphis) is the establishment of places of natural life for the animals that live around it, (5) Protection (protective), to the physical condition of the surrounding nature (high winds, hot sun, gases or dust -dust), (6) beauty (aesthetics), (7) Health (Hygiene) (8) Recreation and education (educational) (9) Socio economic political.

As raised by Eckbo (1956) that the choice of plants for planting to grow well should consider the terms of horticulture (ecological) and physical conditions. Horticultural terms, namely the response and tolerance to temperature, water requirements, needs and tolerance for sunlight, soil requirements, pests and diseases, and other physical conditions that purpose planting, cultivation requirements, canopy shape, color, aroma.

Elements of the urban forest

Functions and benefits of forests, among others, to deliver results, pencagaran flora and fauna, soil and water erosion control, climate amelioration. If the forests are located in the city functions and benefits of forests, among others, creating a micro climate, engineering, architectural, aesthetic, modification of temperature, seepage of rain, wind and air protection, air pollution control, waste management and reduce the reflection of sunlight, soil erosion control , reduce runoff, binding soil. Construction vegetation may regulate water balance by way of interception, infiltration, evaporation and transpiration.

 Examine the function of urban greening and forest functions can be said that urban greening is an element of the urban forest. While the urban forest is a part of urban green open space. Urban forests (urban forestry) in Grey and Denehe (1978), includes all woody vegetation in residential neighborhoods, ranging from small villages to large cities. Fukuara et al. (1988) argued about the urban forest, the open space overgrown woody vegetation in urban areas that provide maximum environmental benefits to residents of the city in the usability of protection, aesthetics and other specialty recreation.

 Meanwhile, according to Grey and Denehe (1978), urban forests (urban forestry) includes all woody vegetation in residential neighborhoods, ranging from small villages to large cities. Given the nature of the yard contains forest that aspires to the interests of the people, the forestry development of this nature seems to be more democratic grounds that agroforestry systems managed by the people. The yard can produce wood, bamboo, carbohydrates, proteins, fats, vitamins and medicines.
