The African frankincense tree (Boswellia dalzielii Hutch.) is a species that occurs in Togo, specifically in the village of Tami in northern Togo. The current number of mature individuals of B. dalzielii is estimated to be 202. Its EOO is estimated to be 1293 km2, and its AOO is 4 km2. Currently, the species is known in only one location. The number of mature individuals qualifies B. dalzielii for criteria D in the Endangered category. Its EOO qualifies the species for criteria B in the Endangered category and with its AOO qualifies the species for B in the Critically Endangered (CR) category. However, the following risks have been identified: overgazing, insect infestation, fire, and a continuing decline in the quality and extent of the habitat, as well as the number of mature individuals. Therefore, the highest category of threat the species meets is B (CR B2ab (iii, iv).
