Types of forests and their importance to mankind

The importance of forests

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 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.

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. 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.

Don't miss the forest for the trees. Here are a few reminders why woodlands are wonderful.

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. Biotic Environment Ablotic Environment The physical environment controls the organisms, and organisms also influences and control the abiotic environment in many ways.

Influence on Air Temperature Forest vegetation reduces mean annual temperature five feet, above ground from 0. The effect of a forest in reducing temperature Is much greater at 5 feet above ground than in the tree crowns.

The following table shows the extent to which species influences the effect of vegetation on air temperature. Concurrent conclusion of various investigation on the effect of forests on air temperature are: Influence on Precipitation Air of forest is cooler and moister, than a-r in the open.

Forest increases the precipitation of any 3rea. As air cools in rising, precipitation increases with increase in elevation.

And so do we. Every day, we send the latest research to our 40,000+ subscribers.

The effect of forest vegetation on precipitation relates to its effect on: The forested mountains increase precipitation with increase in elevation to a much greater degree than denuded mountains. Effect of forest on precipitation varies with the species, coniferous trees having a greater influence than broadleaved species Weber, Forest cover profoundly influences evaporation of water from the land.Important Forest Trees and Their Uses.

Important Forest Trees And Their Uses (Originally Published ) Of our native trees, the white pine is one of the best and most valuable. It is a tall straight tree that grows to a height of to feet.

It produces wood that is light in . Forests are of immense economic importance to us. For example, plantation forests provide humans with timber and wood, which is exported and used in all parts of the world.

They also provide tourism income to inhabitants (people living in or close to forests) when people visit to see the best of nature.
