The Desert regions are neglected natural regions where rainfall is low and erratic, availability of water is limited and plantation is difficult due to extreme temperatures, dry atmosphere and high evaporation. Plantation in these regions is difficult due to uncertainty of rains and recurrent droughts. Harsh environmental conditions make germination and survival of trees shrubs and grasslands difficult. Grasses are grown with impact of rains are either grazed by livestock or burnt by scorching heat. Human interface have created further problems through uncontrolled grazing by livestock, encroachment in forest and plantation lands for cultivation purposes. In this process trees, shrubs and plants have been removed for fuel wood, fodder and timber requirements. Low water availability has further aggravated problem of vegetation. Most of tropical desert regions were dense forests but now largely denuded. Animals of tropical desert regions are surviving in harsh environment and developed adaptability to face all ecological conditions. Birds have mobility and fly to other regions to meet their food and water requirements while some migratory birds have seasonal visits. Large mammals have mobility to reach water points but other species have become accustomed of desert conditions. All animal species found in desert regions have made their own strategies to face extreme hot and cold environment. Forests and plantation areas are necessary for hiding, hunting and reproduction of animals and animals are helpful for protection of trees, shrubs and vegetation by destructing harmful species. Plantation regions have remained survival base of animal species and with continuous denudation of vegetative cover, many desert animal species are extinct and other are struggling for their survival in absence of their habitations.
