Each winter in Zambia, Africa, the dry season saps the land of moisture and sets off a battle for survival. Hippos and crocs guard the shrinking Luangwa River. Lions and leopards plot their attacks on migrating beasts in order to feed their cubs. Standing tall like a beacon of brilliant green in this bleak landscape stands something that defies nature's rhythms: a sausage tree. It's a miracle of Zambia that bears sweet gifts of large fruits and crimson flowers that sustain these wild residents until the unforgiving season ends.
