Landscapes are the most natural form of the environment. The father of Landscape ecologyCarl Troll (1971) defines landscapes as totally natural and human living space. It may be formed out of a continuous forest, a treeless farmland, lowland, hill country, mountains, valleys, urbanized area and industrialized area richly varied farmland, nature reserves wild landscapes etc. Ecological Definition of Landscape Today, Landscape management is influenced by people's perception of the environment.

Landscapes have often been subject to human intervention and pressure which may tend to deflect succession to form a plagioclimax community.
This may lead to spoilage of landscape due to waste accumulation. The African savanna was once a forest but was cleared by farmers for agriculture, the soils in these areas were further impoverished by this activity and now the soil can only support grasses and shrubs that are tolerant of drought and fire. A fact that is important here is the spoilage of soil by waste accumulation which can no more support tree species for a regeneration of forest as a climatic climax community. How to create Natural Green Funeral Burial Sites/Grounds? Eco-friendly Biodegradable Coffins - Environmental Science Studies - Issues, Affects, Causes.

Arthor George Tansley (1891-1955) - Environmental Science Studies - Issues, Affects, Causes. Arid and semi-arid ecosystems involve the study of living things and their relationship with their environment i.e climate, region (land like desert) rather than just looking at individual types of plants and animals.
The living things (biotic) are the green plants, animals, bacteria fungi etc and their environment (abiotic) constitutes the earth, air, water, minerals and compounds such as Carbon, Nitrogen, Oxygen, Carbon dioxide and others, both influencing each other which is necessary to maintain life. The composition of biotic and abiotic phases are the building blocks of an arid ecosystem area.

The dominant producer plants are mostly annual plants which manage (therophytes) to avoid drought by passing the dry period as dormant seeds. This vegetation also persists by means of underground storage organs. Xerophytic shrubs and stem succulents are adapted to tolerate drought. The proportion of plant life forms in semi-arid ecosystems is nearly 26 percent phanerophytes (woody plants with buds above soil surface) nearly 18 percent hemicryptophytes (herbs with buds at soil levels) 6 percent cryptophytes (herbs with buds below the soil surface) and 41 percent therophytes.
Importance and Protection of Forest Habitat - Environmental Science Studies - Issues, Affects, Causes. Conservation is the protection of something which people perceive as being of value.

By the time of June 1992 Earth Summit in Rio-de-Janeiro (Brazil), countries had developed a series of principles for forest conservation and its sustainable use. The Rio statement says the forest with their complex ecological processes, are essential to economic development and the maintenance of all forms of life. Forests are the source of wood, food and medicine and rich storehouses of several biological products yet to be discovered. Forest effects on causing rainfall are important. They act as reservoirs of water and carbon that would otherwise get into the atmosphere and act as a greenhouse gas. Steps Taken to Conserve Forest and Wildlife. Objectives of Joint Forest Management Programme in India - Environmental Science Studies - Issues, Affects, Causes. Joint forest Management (JFM) - The galloping rate of depletion of India's forest resources is a serious problem.
Sustaining the forest resource base against the growing human and livestock population pressures, industrialization, urbanization, and overall economic development have earned a priority among the joint forest management regimens. Apart from developmental pressure, the dependence of forest user groups is a crucial factor in the state of Indian forests. Forest conservation priorities cannot be determined in isolation from local people. This must be complemented by policies promoting sustainable and equitable development of the forest resource base as a whole. Sustainable forest management occurs when the level of exploitation resources is not greater than the ability of the ecosystem to replace it.
