Habitat fragmentation is the reduction of large tracts of habitat leading to habitat loss. Temperate Himalayan wetlands provide important habitat and layover sites for migratory birds. Fish are more dependent on wetland ecosystems than any other type of habitat. Botswana has diverse areas of wildlife habitat. The species distribution is easily influenced by changes in freshwater habitat and climate. Gerrids are largely hunted by birds of a wide range of species dependent on habitat. Fragmenting ecosystems decreases quality of the habitat. Small fragments are therefore unfavourable for species that require interior habitat. This is also true for species living within these habitat fragments. Hybridization is currently an area of great discussion within wildlife management and habitat management. They have also helped in gathering support for habitat conservation. A favorite prey for the lynx in its woodland habitat is roe deer. It appears to be dependent on forest habitat. This fish is locally abundant in its freshwater habitat. This is due presumably to the enclosed mixed forest habitat of Hokkaido.
