ABSTRACT
Forest is an area set a side for the pt-Auction of timber and other forest produce, or maintained under woody vegetation for certain Indirect benefits which it provides.
Forest constitute some of the most complex natural ecosystems of the world. Environment may be analyzed into a number of factors, such as Soil, Moisture, Wind, Temperature etc. The psycho physiological influence of trees in the form of purified air, clean water, rests and recreation, scenic enjoyment reduced noise level and spiritual replenishment are being fully appreciated. The major parts of healthy environment are FOREST.
The influence of forest on their environment forms part of a vast and complex relationship between environment and forest vegetation Environment generally refers to the sum total of various components of universe that affect life on this earth such as soil, water, and climate etc. Man in generally interferes the environment by destroying vegetation through over-exploitation and mismanagement. Forest improves the environment in many ways such as:
Relative humidity of air is increased. increase fertility of surface soil.
These add large quantities of organic matter in soil by which water and nutrient holding capacity of soil is increased. Domestic animals as well.
In the past, consideration of forests, influence on climate was focused at the microclimate or local level. More recently, increasing attention has been directed at the potential, impact of forests on global conditions.
FOREST ENVIRONMENT
The forest environment or site consists of the physical environment surrounding the aerial portions of the tree (climatic factors) and that surrounding the subterranean portion (edaphic factor) and the third one is biotic factor. External influences, particularly fire, grazing and browzing animals and humans, affect markedly the nature of sites and their capacity to support tree growth.
As the forest becomes established and develops, the site itself is greatly changed. Forest cover moderates the extreme diurnal temperature regime of open sites resulting in more uniform conditions. Wind velocity is slowed in the vicinity of tree crowns and becomes negligible within the forest.
Trees crowns intercept sunlight and alter the quantity and quality of radiation reaching forest floor compared with that reaching open sites. On the forest floor, accumulating layers of leaves, twigs and other litter attract a characteristic grouping of plants and animals that live on decaying organic matter and on each other.
1.1. Biotic Environment
Ablotic Environment
The physical environment controls the organisms, and organisms also influences and control the abiotic environment in many ways.
