Which of the following is an example of habitat fragmentation?
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.

What is fragmentation in geography?
Fragmentation is often defined as a decrease in some or all types of natural habitats in a landscape, and the dividing of the landscape into smaller and more isolated pieces. … Fragmentation can be caused by natural processes such as fires, floods, and volcanic activity, but is more commonly caused by human impacts.
What are examples of habitat destruction?
Habitat destruction occurs when natural habitats are no longer able to support the species present, resulting in the displacement or destruction of its biodiversity. Examples include harvesting fossil fuels, deforestation, dredging rivers, bottom trawling, urbanization, filling in wetlands and mowing fields.
What are the reasons for fragmentation of habitat?
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.
What is habitat loss and fragmentation?
Habitat loss occurs when natural habitats are converted to human uses such as cropland, urban areas, and infrastructure development (e.g. roads, dams, powerlines). … Habitat fragmentation occurs when large blocks of habitat are cut into smaller pieces by development such as roads or housing.
