U.S. Fish & Wildlife Service Asian Elephant Conservation Act Summary Report 1999-2001 The mission of the U.S. Fish and Wildlife Service is working with others to conserve, protect and enhance fish, wildlife, plants and their habitats for the continuing benefit of the American people. Cover: A subadult male Asian elephant in the fertile grasslands of the Brahmaputra River floodplains, Kaziranga National Park, Assam, India. The forested hills in the background are an essential wet season component of this habitat which is part of India’s Kaziranga-Karbelong-Intanki Elephant Reserve, home to 1,500 to 2,000 elephants.

The conservation pressure brought on by these conditions planning to has resulted in the conversion of forest conserve cover to agriculture and villages, fragmenting elephant habitat and maximum populations. While the Asian elephant is biodiversity and the well-known elephant of circuses and ecosystem elephant rides, the African elephant’s function, the plight in the wild has been more successfully popularized by the western importance of media. Relatively few people are aware that conserving the the Asian elephant is critically endangered Asian elephant in the wild. across as much of Several distinctive anatomical its range as characteristics differentiate the Asian possible elephant from the larger, more abundant cannot be African elephant (Loxodonta africana). For example, the ears of Asian elephants overemphasized. are smaller; the forehead has two distinct There are also lobes, rather than the single dome of the profound African elephant; and, the highest point on ideological and an Asian elephant is the top of the head, versus the top of the shoulder in the religious reasons African elephant. In addition, only to preserve this 60 percent of male Asian elephants have species and halt tusks, while tusked males and females are its decline. the rule in the African species. Due to poaching, which selects against tusk- bearing males, many localities throughout Asia have depleted numbers of mature elephant bulls, resulting in an abnormal population-age structure and sex ratio. The long-term impacts of this factor on the conservation of the Asian elephant is unknown. This report presents a summary and highlights of the work supported by the Asian Elephant Conservation Fund (Fund) during 1999-2001. The Fund is administered and coordinated by the Division of International Conservation, U.S. Fish and Wildlife Service (Service), Department of the Interior.

USFWS/Fred Bagley 3 If wild populations of Asian elephants are to survive into the 22nd Century, habitat, such as this in India’s Nilgiris and Eastern Ghats Elephant Reserve must be protected. Conversion to farmland is a primary threat. For Department Provincial Forestry Yunnan example, clear-cutting and an expanding agricultural frontier have already displaced Asian elephants from much of Yunnan Province, China (top and center) and Indonesia’s Lampung Province (bottom).
