HAITAT CONSERVATION

Habitat conservation is a land management practice that seeks to conserve, protect and restore, habitat areas for wild plants and animals, especially conservation reliant species, and prevent their extinction, fragmentation or reduction in range.[1] It is a priority of many groups that cannot be easily characterized in terms of any one ideology

IMPORTANCE OF HABITAT CONSERVATION

The conservation of natural resources is the fundamental problem. Unless we solve that problem, it will avail us little to solve all others.
Theodore Roosevelt
Most of the species extinctions from 1000 AD to 2000 AD are due to human activities, in particular destruction of plant and animal habitats. Raised rates of extinction are being driven by human consumption of organic resources, especially related to tropical forest destruction.While most of the species that are becoming extinct are not food species, their biomass is converted into human food when their habitat is transformed into pasture, cropland, and orchards. It is estimated that more than a third of the Earth's biomass is tied up in only the few species that represent humans, livestock and crops. Because an ecosystem decreases in stability as its species are made extinct, these studies warn that the global ecosystem is destined for collapse if it is further reduced in complexity. Factors contributing to loss of biodiversity are: overpopulation, deforestation, pollution (air pollution, water pollution, soil contamination) and global warming or climate change, driven by human activity. These factors, while all stemming from overpopulation, produce a cumulative impact upon biodiversity.

forest protection

Forest protection is a general term describing methods purported to preserve or improve a forest threatened or affected by abuse. There is considerable debate over the effectiveness of forest protection methods.
One simple type of forest protection is the purchasing of land in order to secure it, or in order to plant trees (
afforestation). It can also mean forest management or the designation of areas such as natural reservoirs which are intended to be left to themselves.
However, merely purchasing a piece of land does not prevent it from being used by others for
poaching and illegal logging. A better way to protect a forest, particularly old growth forests in remote areas, is to obtain a part of it and to live on and monitor the purchased land. Even in the USA, these measures sometimes don't suffice because arson can burn a forest to the ground, leaving burnt areas free for different use.
Enforcement of laws regarding purchased forest land is weak or non-existent in most parts of the world. In the increasingly dangerous South America, home of major
rainforests, officials of the Brazilian National Agency for the Environment (IBAMA) have recently been shot during their routine duties.

Forest cnservation

The nascent conservation movement slowly developed in the 19th century, starting first in the scientific forestry methods pioneered by the Germans and the French in the 17th and 18th centuries. While continental Europe created the scientific methods later used in conservationist efforts, British India and the United States are credited with starting the conservation movement.
