Gilbert’s potoroo inhabits long, unburnt stretches of shrubland on deep, sandy soil.  They are also noted to be the “constant companion” of the smily quokka, which is perhaps why Dr Sinclair caught the potoroo in her quokka traps.  The fact that the potoroo requires such dense vegetation that has been unburnt for decades can have a direct effect on its survival.


African Spurred Tortoise (Geochelone sulcata)

The African spurred tortoise is native to the Sahara Desert and the Sahel, a transitional ecoregion of semiarid grasslands, savannas, and thorn shrublands found in the countries of Burkina Faso,Chad, Eritrea, Ethiopia, Mali, MauritaniaNigeria, Senegal, and Sudan In these arid regions, the tortoise excavates burrows in the ground to get to areas with higher moisture levels, and spends the hottest part of the day in these burrows. This is known as aestivation. Burrows may average 30 inches in depth; some dig tunnel systems extending 10 feet or more underground.

C. sulcata is the third-largest species of tortoise in the world after the Galapagos tortoise, and Aldabra giant tortoise, and the largest of the mainland tortoises. Adults can reach 83 cm (33 in) and can weigh 105 kg (231 lb). They grow from hatchling size (2–3 in) very quickly, reaching 6-10 in (15–25 cm) within the first few years of their lives. The lifespan of an African spurred tortoise is about 50–150 years, though they can live much longer. (The oldest in captivity is 54 years, located in the Giza Zoological Gardens, Egypt, 1986.)WIKIPEDIA
