According to Bachman et al. (2020), each Aloe on the IUCN Red List indicate that 39% of the species are threatened with extinction. The major threats include the intensification and expansion of crop and livestock farming, and collecting of Aloes for medicines. About a third of East African Aloe species have limited distributions, and most are locally endangered (Bachman et al. 2020). In Tanzania, Aloes which are recognized as critically endangered species (CEAs) by the International Union for Conservation of Nature (IUCN) receive limited conservation efforts because many conservation projects direct their efforts towards animals, and neglect endangered/rare, or understudied plant species. Aloes are among the plants which receive less conservation attention despite their ecological and medicinal importance. A few remaining individuals of CEAs i.e. A. boscawenii are found in Mkinga district, A. dorotheae in Handeni district, and A. flexilifolia and A. leptosiphoni in Lushoto district in Tanga region. These sites are acknowledged by the IUCN as the hotspots and ecologically important for conservation of CEAs. The population of CEAs is declining and efforts to save them from local extinction is lacking. Because of this, degradation of their natural habitats, and collection of CEAs for medicine and trade increase their extinction risk. Ex-situ conservation in botanical gardens might be a best alternative approach for protecting CEAs from local extinction. Based on the IUCN research classification scheme, this project will assess the current population, distribution, and ecological habitats status of CEAs; establish CEAs botanical garden; and conduct conservation education to sensitize local people to protect CEAs.
