Importance:

The greater padloper tortoise is endemic to South Africa and contributes to ecosystem stability in the Karoo. As the largest species in the genus Homopus, it is of scientific interest for studies of limb development, as it is one of only two Homopus species with four digits on each foot.

Species Card Details

Importance:

Widely spread across Africa, this tree is known for its iconic flat-topped canopy, often depicted in films set in Africa. In Central Africa, a bark/root decoction treats urinary inflammation, while leaves, bark, and resin serve as astringents for colds, chest issues, diarrhea, hemorrhages, and eye inflammation. In Tanzania, bark is used for gonorrhea treatment. The edible gum acts as a strong adhesive, and twine from the inner bark is used for threading beads.
