Proposal The Proponents propose the listing of Giraffa camelopardalis on CITES Appendix II in accordance with Article II, paragraph 2 (a), of the Convention: “all species which although not necessarily now threatened with extinction may become so unless trade in specimens of such species is subject to strict regulation in order to avoid utilization incompatible with their survival.” The species also meets Criterion B of Resolution Conf. 9.24 (Rev. CoP17), Annex 2a: “It is known, or can be inferred or projected, that regulation of trade in the species is required to ensure that the harvest of specimens from the wild is not reducing the wild population to a level at which its survival might be threatened by continued harvesting or other influences.” In addition, the species meets the precautionary measures found in Annex 4 of that Resolution: “when considering proposals to amend Appendix I or II, the Parties shall, by virtue of the precautionary approach and in case of uncertainty either as regards the status of a species or the impact of trade on the conservation of a species, act in the best interest of the conservation of the species concerned and adopt measures that are proportionate to the anticipated risks to the species.

    Made available at http://www.aszk.org.au/Husbandry%20Manuals.htm with permission of the author Literature Review of Giraffe Giraffa camelopardalis By Lorraine jolly 2002 [email protected] 1 Made available at http://www.aszk.org.au/Husbandry%20Manuals.htm with permission of the author ABSTRACT The giraffe is the biggest ruminant and the tallest mammal, adults giraffe reach heights of 4-5.5m and weigh from 550-1930 kg. Giraffe are in the mammalian order Artiodactyla, and of the family Giraffidae, consisting of two living genera and two species (Okapia johnstoni and Giraffa camelopardalis) both are native to the African continent. Giraffe are further taxonomically divided into subspecies. There are nine recognised subspecies of giraffe, each subspecies has been identified by a particular geographical range, coat pattern and coat colouration. The home ranges of several subspecies overlap, and subspecies hybridization occurs in the wild. The exact pattern is unique to each individual as a fingerprint, the coat pattern is maintained throughout life. In the giraffe’s present range, from the Eastern Transvaal to West Africa, their occurrence is patchy and discontinuous, many are restricted to protected conservation areas. Their range continues to contract, an estimated total of 140 700 wild giraffe remain. Giraffe are widespread and successful herbivores of the African savanna, giraffe browse on trees and shrubs of a variety of species but are highly selective. The height of the giraffe gives it access to a band of vegetation on which to browse that is out of reach of other browsers. Giraffe home ranges are vast ranging from 160 km² to 650 km².

    The Ecology and Behaviour of Giraffe in Northern Botswana Kylie N. McQualter Centre for Ecosystem Science School of Biological, Earth and Environmental Sciences University of New South Wales Australia A Thesis submitted in fulfilment of the requirements for the degree of Doctor of Philosophy within the University of New South Wales January 2018 THE UNIVERSITY OF NEW SOUTH WALES Thesis/Dissertation Sheet Surname or Family name: McQualter First name: Kylie Other name/s Nicole Abbreviation for degree as given in the University calendar: PhD School: School of Biological, Earth and Environmental Faculty: Science Sciences Title: The Ecology and Behavior of Giraffe in Northern Botswana Abstract Northern Botswana is one of the giraffe strongholds across its geographic range in the absence of, or with low impact from, the major anthropological threats faced elsewhere. Yet despite its conservation significance, until now, no giraffe- specific ecological or behavioural studies have been undertaken. Moreover, Africa’s giraffe population has been significantly reduced over the last two decades, and the pressure on giraffe habitats and populations is likely to increase as the human population continues to expand, and the effects of climate change take their toll. As such, it is important to establish an ecological and behavioural baseline for giraffe in the unique ecosystems. This study provides baseline data on the behaviour and ecology of giraffe in the dry savannah and woodlands of the northern Chobe region and the wetland system of the Okavango Delta (NG26) in northern Botswana. The study first examines the home ranges, seasonal ranges and daily movements of giraffe in the two study areas.
