Landscape Ecology definition and structures. Human and Natural Impact on Landscapes.

What does landscape means? Landscapes are the most natural form of the environment. The father of Landscape ecology Carl 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. In the British Isles, the landscape has been formed by the interplay of human and physical variables. Landscape are living habitat for all organisms-humans, their population, communities, and ecosystem. Most habitats have been managed in the same way. Often it is difficult to see where physical factors dominate over human ones.


Human Impact on Landscapes:-

Human influences such as afforestation, reservoirs, grazing, improved pasture


Natural impact on Landscapes:-

Physical influences such as altitude, degree of slope, thin leached soil, exposure to strong winds etc.

Some lowlands are governed by flooding, others by forced drainage. Rock and soil type also play a role in determining nature of some community.


Human Aim and Objectives to use Landscapes

People manage landscapes for different aims and objectives. Nature Reserves have been managed to create a range of habitats which favors diversity of species and to provide amenity value for the visitors who come to the reserve. This is considered to be an important aim within an urban area. Socio-cultural impacts have also shaped our landscapes.
