The number of elephants that are to be protected must be The objective of an Action Plan is to provide equivalent to or above the minimum required to ensure governments, national and international conservation the survival of the species. agencies, researchers and conservationists with concise, up-to-date information on the status of Elephas maximus, As Ferrar (1983) righdy argues, at any but the lowest as well as an objective and practical management density, large wild animals and people are fundamentally framework for ensuring the survival of as many viable incompatible. This incompatibility increases rapidly as populations of the elephant as possible in as wide a both elephant and human densities increase. Thus, the range of its habitats as is feasible. This objective has maximum number of elephants that a system of PAs to be achieved in the context of continued increase in and their surrounding regions can support depends on human population in South and Southeast Asia, rising the neighbours' tolerance of the species (Child 1995). living standards in many Range States, the imperatives The present rate of human population growth, the of opening up new land for agriculture and settlement, constant land hunger, and increasing expectations for and the need to minimize human-elephant conflict. The improved living standards, exacerbate the problem for Action Plan thus aims to promote the conservation of as habitat conservation. More often, legitimate aspirations many healthy populations of the elephant both within for better living conditions cause greater Pressure on Protected Areas (PAs) and as many animals outside these elephant habitat than sheer growth in human numbers. areas as the land can support and the landholders will The attitudes of local communities are strongly influenced accePt. by whether the high cost of having the elephant in their neighbourhood can be offset by the revenues it generates Throughout its range, the Asian elephant is increasingly through other means such as small-scale ecotourism. The being confronted by socio-economic and political future of the elephant in Asia is inextricably linked to the pressures that threaten to destroy the very habitats set aside welfare of the rural people with whom the animal shares for its long-term survival in the wild. For wildlife, such the land. Conservation programmes that ignore human as the elephant, and PAs to survive on a significant scale, interest are doomed to failure. As Sugal (1997) succinctly they must be "socio-politically acceptable, economically puts it, the hard lesson in ecology as in economics is viable, and ecologically sustainable" whether it be in that "there are no free rides; in one way or another' Africa or Asia (Child 1995). Conservation of the elephant everything pays its way". in Asia therefore depends on the political will and concrete actions of the governments involved. Vithout Thus, the most practical and appropriate strategy of political will and commitment, the implementation of conserving elephants in the long term is the landscape many of the conservation recommendations outlined approach that incorporates PAs within a matrix of other here will be impossible. Government commitment and forms of land use including logging areas, non-timber action must be obviously based on sound ecological, product extraction areas, grazing land for livestock, economic, and cultural arguments for conservation of and even some agricultural activity.

But setting aside sufficient habitat large enough to accommodate the home ranges of such long-ranging The success of the Action Plan will depend on animals in Asia, where people and elephants compete how effectively each government implements the for the same resources, is practically impossible. Most key recommendations. An action plan that is not wildlife sanctuaries, national parks or other categories of implemented is little more than an interesting academic nature reserves in Asia are not large enough individually exercise. It is most desirable that each country develop its to support elephant populations, and farmers or villagers own National Action Plan for elephant management and living along the periphery of such reserves or in enclaves conservation. Each country should identify its national within are highly vulnerable to what happens when priorities and seek the necessary resources to put the such large herbivores do not stay inside their boundaries strategy into action. The cost of implementing the (Sugal 1997). It vrill not be possible to save all of Asia's recommendations given in this Action Plan may be high, wild-elephants, but losses can be kept to a minimum if and therefore calls for increased financial allocations economic development plans take into account the needs from Range State governments and international of the elephant, and planning for elephant conservation donor agencies for elephant conservation in most Gajah 25: (2006)

For maintaining on our current scientific knowledge of elephant biology the long-term evolutionary potential of a populadon and ecology, and many of these have been outlined in about 1.0 times the above number of elephants may be earlier publications as well (Santiapillai andJackson L990; needed.

Therefore, in contrast to the Management of human-elepbant conflia conservation of a species such as the tiger, the simple core-buffer concept for a management unit will not hold Despite the special esteem in which the elephant is held in the case of the elephant. However, according to Lahiri- in Asia, the relationship between humans and elephants Choudhury (1991), the principle of total protection will has undergone a drastic change; contraction and loss of continue to apply to crucial habitat pockets, such as areas habitat, as Lahiri-Choudhury (1988) points out, have where elephants take shelter during the 'pinch period' made it antagonistic. People encroach on the elephant's (usually dry season); cover used as daytime refuge for land; elephants eat the crops cultivated on the occupied nocturnal foraging; saltlicks to which elephants must land; people strike out at elephants for doing this; return periodically for trace elements, and corridors elephants retaliate. This is the crux of the human-elephant linking different parts of an elephant range. conflict in Asia (Lahiri-Choudhury 1988). Understanding the relationship between human settlement patterns and Corridors to facilitate elephant nrcoement elephant abundance is fundamental to predicting the viability of elephant populations (Floare and Du Toit One of the major threats to the elephant in Asia is leee). degradation and fragmentation of habitat.

In the year PAs for an elephant population, forest corridors should 2001 alone, wild elephants were killed at a rate of three be maintained to facilitate movement of elephants per week in the conflict, which also claimed the lives of between PAs. flhen landscapes are threatened with 44 people. In Sri Lanka, human-elephant conflict seems fragmentation, a sysrem of corridors may be one practical to have replaced poaching as the major threat to wild way to ensure connectivity for elephant movement elephants. People and elephants seek the same resources: (Sukumar 2003), and to expand elephant habitats to a fertile soils and water (Parker and Graham 1989). The reasonable size.

Elephants are killed in Sri Lanka simply because The proper design and management of such forest they interfere with agriculture. Even in countries such corridors will help minimize conflicts between elephants as Vietnam with very few wild elephants, the conflict is and people. It will also prevent the isolation of herds, acute because of the 'pocketed herd' phenomenon. and improve the genetic and demographic viability of the overall population. However, such corridors, to be In many pans of the range of the elephant in Asia, effective, should be at least about 1km wide; however, the human-elephant conflict has escalated for a variety as the Project Elephant document asserts, if the distance of reasons. The resolution of the confict between between two habitats is too long, then the width has elephants and sedentary, agriculturally-based people to be much more. But longer corridors may enable is a priority issue in the conservation of the species the elephants to spill over into the adjacent human ftIoare 2001). ff unresolved, the conflict may lead to the settlements, and thereby exacerbate the conflict between eventual destruction and elimination of elephants from man and elephant. Therefore, it is imponant that the agricultural areas.'Ways to minimize the human-elephant boundary of the corridor be prorected (Sukumar 2003). conflict remains one of Asia's highest conservation priorities (Kemf and Santiapillai 2000). The management International cooperation is required where migration of human-elephant conflict has to be integrated into a routes cross frontiers.

Although the shock is Being very intelligent, elephants soon learn that painful, it does not injure or disable the elephant (Osborn traditional methods of deterring elephants - banging and lfelford 1998).
