Gum Arabic Production and Population Status of <i>Senegalia senegal</i> (L.) Britton in Dryland Forests in South Omo Zone, Ethiopia

<i>Senegalia senegal</i> (L.) Britton is a multi-purpose dryland tree species that produces gum arabic, a commercially valuable product. However, this resource is underused in Ethiopian dryland areas. The aim of this study was to evaluate the population status and potential gum yield of...

Britton is a multi-purpose dryland tree species that produces gum arabic, a commercially valuable product. However, this resource is underused in Ethiopian dryland areas. The aim of this study was to evaluate the population status and potential gum yield of <i>S. senegal</i> growing in natural stands in South Omo Zone, Ethiopia. Forty-five sample plots, each measuring 20 × 20 m, were established at 500 m intervals along transects, with 1 m<sup>2</sup> subplots located within the main plots to determine regeneration. <i>S. senegal</i> trees with a diameter at breast height of between 2 and 12 cm were most prevalent. Forty-two tree species were associated with <i>S. senegal</i>, of which 16 were gum- and resin-producing species. <i>S. senegal</i> was positively associated with <i>Vachellia tortilis</i>, <i>Senegalia mellifera</i>, <i>Vachellia nilotica</i>, <i>Commiphora edulis</i>, and <i>Dobera glabra</i>. <i>Senegalia senegal</i> comprised approximately 35% of regenerating trees. The maximum gum arabic yield obtained was 3948 g tree<sup>−1</sup>. Linear models of dendrometric variables indicated that gum arabic yield is better predicted by tree diameter than by height. Despite the limitations of this pioneer survey, the population status and yield potential suggest that gum arabic could be sustainably produced and commercialized in natural stands of <i>S. senegal</i> in the studied dryland areas, providing local communities with supplementary seasonal incomes.Gizachew ZelekeTatek DejeneWubalem TadessePablo Martín-PintoMDPI AGarticlecommercializationgum and resingum arabic<i>Senegalia senegal</i>standtappingEnvironmental effects of industries and plantsTD194-195Renewable energy sourcesTJ807-830Environmental sciencesGE1-350ENSustainability, Vol 13, Iss 11671, p 11671 (2021)
