What is habitat fragmentation pdf
Habitat destruction typically leads to fragmentation, the division of habitat into smaller and more isolated fragments separated by a matrix of human-transformed land cover. The loss of area, increase in isolation, and greater exposure to human land uses along fragment edges initiate long-term changes to the structure and function of the remaining fragments ( 3 ).

Habitat fragmentation, or the breaking up of habitat into smaller pieces (Figure 2), is a second major effect of human land use. Its prevalence is difficult to summarize because it is confounded with habitat loss and can be measured in many different ways. Understanding of the effects of habitat loss and fragmentation on populations has been hampered by a vague conceptualization of habitat

Introduction. Loss of biodiversity is a worldwide concern. One primary cause of species loss is habitat destruction and fragmentation (Tilman et al. 2001), but the rate of extinctions might be accelerated due to other causes such as invasion by alien species, overexploitation, climate change, habitat deterioration and extinction cascades

Habitat fragmentation can result from natural processes such as fi re or landslides, or from human processes, such as cutting forests down for fuel and lumber.
Habitat fragmentation creates landscapes made of altered habitats or developed areas fundamentally different from those shaped by natural disturbances that species have adapted to over evolutionary time (Noss and Cooperrider 1994 in Meffe et al. 1997).
fragmentation is used specifically to mean habitat fragmentation independent of habitat loss (i.e., habitat fragmentation per se). Importantly, studies of patch size effects and patch isolation effects do not provide evidence

Habitat fragmentationisan issue of primary concern in conservation biology. However.both the concepts of habitat and fragmentation are ill-defined and often misused. We review the habitatconcept
Habitat Loss, Degradation, and Fragmentation . Habitat Conversion/Transformation – change in habitat, can result in degradation or loss; conversion often implies loss •Habitat Degradation – decline in habitat quality, affects many but not all species, may be temporary; Primary cause of species extinction globally and in most countries •Habitat Loss – habitat changed in way that
