Can Addax and Oryx be saved in the Sahel?

Abstract: Very few reserves exist to protect the arid-lands fauna of West Africa, particularly in the sub-desert zone, and the large mammals, such as addax, scimitar-horned oryx and dama gazelle are disappearing. New reserves are planned but they could be too late. Many permanent waterholes have been dug, and the nomads (and their livestock) tend to stay near them, depriving the wild animals of their traditional dry-season haunts. Firearms have made hunting easier, and the slow-running desert animals cannot compete with… Show more

“…It would, thus, appear that the data on oryx play further support the physical training hypothesis : male and female oryx calves, by playing frequently together, thereby, trained for future intersexual interaction as adults. The reason why interaction between male and female oryx was so prevalent is speculative, but interaction may have evolved to enable 99 to acquire resources critical to their reproductive success (RALLS 1976) in the patchy, unpredictable sub-desert environment (GILLET 1966;NEWBY 1980;SHANTZ and MARBUT 1923;STEWART 1963). Additionally, intersexual competition in scimitar-horned oryx may have also been a selective pressure in the evolution of isomorphy in this species (JANIS 1982;BURLEY 1981).…”

“…These significantly enhance the biological diversity of the reserve as a result of their associated temporary pools, floodplains and inundation zones, providing a source of freshwater. The term ‘Sahel’ in Arabic literally translates as ‘shore’ and refers to the ‘sparsely vegetated fringe of sand seas’ (Newby, ): as well as being one of Africa's largest protected areas, the OROAGR is also one of the only designated protected areas that falls in the transition zone between true desert (Sahara) and Sahel.…”

“…Preferred habitat types include rolling dunes, scrub vegetation, and scattered trees or woodlands that provide shade during the dry season (Bassett, 1975;Newby, 1978Newby, , 1988Bemadjim et al, 2012). Oryx feed on a wide variety of grasses and forbs and rarely drink surface water, instead obtaining moisture from grazed vegetation, wild Citrullus melons, and occasionally Acacia seed pods (Gillet, 1965;Dragesco-Joffé, 1993. Historically, oryx were relatively abundant within their range, and were hunted for meat and hides (Dolan, 1966;Newby, 1980Newby, , 1988. Increased hunting pressure, arising from political instability and the introduction of automated weapons and motorized vehicles, along with exclusion from high-quality habitat by nomadic pastoralists and insufficient legal protection, resulted in the species' steady decline during the twentieth century (Durant et al, 2014;Woodfine and Gilbert, 2016).…”

“…The scimitar-horned oryx (Oryx dammah; hereafter "oryx") is a large African antelope adapted to the arid, seasonal grasslands surrounding the Sahara Desert (Newby, 1978(Newby, , 1980Morrow et al, 2013). Once numbering in the hundreds of thousands, oryx ranged across the Sahel from Mauritania to Sudan, performing extensive seasonal migrations across the region (Newby, 1978;Harris et al, 2009).…”
