Detailed explanation-1: -Fragmentation happens when parts of a habitat are destroyed, leaving behind smaller unconnected areas. This can occur naturally, as a result of fire or volcanic eruptions, but is normally due to human activity. A simple example is the construction of a road through a woodland.
Detailed explanation-2: -Habitat fragmentation is frequently caused by humans when native plants are cleared for human activities such as agriculture, rural development, urbanization and the creation of hydroelectric reservoirs. Habitats which were once continuous become divided into separate fragments.
Detailed explanation-3: -The example for the fragmentation is the Amazon rainforest that leads to extinction of species which is being cut and cleared for soybean cultivation for conservation to grassland for raising beef cattle. This is the fragmentation of the land which leads to population declines.
Detailed explanation-4: -Forest fragmentation refers to a loss of forest and the division of the remaining forest into smaller blocks. Fragmentation is of concern primarily because of its impact on the conservation of biological diversity.
