Q: Which plant, introduced by Europeans, today covers large parts of Lake Victoria?
A: Water Hyacinth: This plant was introduced to Africa by Europeans; it reproduces rapidly and covers large areas of the lake. The dense mat of plants block sunlight needed for survival by the life below the surface.

Q: Through which two major conservation areas runs the Mara River?
A: The Mara River Basin is about 13,750 square kilometres, of which about 65 percent is located in Kenya and 35 percent in Tanzania.

Q: Which of the Big Five species found in the Mara River Basin is the most endangered one?
A: The rhino is the most endangered species of the Big Five. Rhino poaching worldwide hit a 15-year high in 2009. The illegal trade is being driven by an Asian demand for horns, made worse by increasingly sophisticated poachers who are now using veterinary drugs, poison, cross bows and high calibre weapons to kill rhinos. Very few rhinos now survive outside national parks and reserves.
