It is the process by which habitat loss results in the division of large, continuous habitats into smaller, more isolated remnants.
One of the major ways that habitat fragmentation affects biodiversity is by reduction in the amount of available habitat (such as rainforests, boreal forests, oceans, marshlands, etc.) for all organisms in an ecological niche. Habitat fragmentation invariably involves some amount of habitat destruction. Habitat fragmentation is often a cause of species becoming threatened or endangered. The existence of viable habitat is critical to the survival of any species, and in many cases the fragmentation of any remaining habitat can lead to difficult decisions for conservation biologists. Habitat fragmentation can be caused by geological processes that slowly alter the layout of the physical environment (suspected of being one of the major causes of speciation), or by human activity such as land conversion, which can alter the environment much faster and causes extinctions of many species. Habitat fragmentation is often a cause of species becoming threatened or endangered. The existence of viable habitat is critical to the survival of any species, and in many cases the fragmentation of any remaining habitat can lead to difficult decisions for conservation biologists. Causes of Fragmentation. Habitat fragmentation usually occurs because of human activities such as new roads, parking lots and housing developments. Organisms need their specific habitat for survival, and fragmentation is a leading threat to many terrestrial animals. Logging is a major cause of habitat fragmentation in forests. Logging creates clear-cut, open ground areas that were once protected by the cover of trees. Logging roads that are built for the logging trucks to travel on can also be cut through forests, disrupting the habitat. Habitat fragmentation. Habitat fragmentation, as the name implies, describes the emergence of discontinuities in an organism's preferred environment, causing population fragmentation. Habitat fragmentation can be caused by geological processes that slowly alter the layout of the physical environment, or by human activity such as land conversion, which can alter the environment much faster and causes extinctions of many species. Habitat fragmentation is the process by which habitat loss results in the division of large, continuous habitats into smaller, more isolated remnants. A schematic representation of the problem of attributing causality to ‘habitat loss’ versus ‘habitat fragmentation’. (a) In modified landscapes, all measures of spatial habitat configuration are strongly intercorrelated with the amount of remaining habitat, making separation of ‘independent’ effects impossible. In some situations, habitat fragmentation may lead to species becoming threatened or endangered. Smaller fragments of habitat cannot support as many species and individuals as larger habitats, so the size of the new fragmented patches will dictate the continued survival of those species. Habitat fragmentation also creates smaller, isolated populations. Logging is a major cause of habitat fragmentation in forests. Logging creates clear-cut, open ground areas that were once protected by the cover of trees. Logging roads that are built for the logging trucks to travel on can also be cut through forests, disrupting the habitat. The term habitat fragmentation includes five discrete phenomena: 1  Reduction in the total area of the habitat. 2  Decrease of the interior: edge ratio. 3  Isolation of one habitat fragment from other areas of habitat. Habitat fragmentation is often a cause of species becoming threatened or endangered. The existence of viable habitat is critical to the survival of any species, and in many cases the fragmentation of any remaining habitat can lead to difficult decisions for conservation biologists. Habitat fragmentation describes the emergence of discontinuities (fragmentation) in an organism's preferred environment (habitat), causing population fragmentation. Habitat fragmentation is often a cause of species becoming threatened or endangered. The existence of viable habitat is critical to the survival of any species, and in many cases the fragmentation of any remaining habitat can lead to difficult decisions for conservation biologists.
