These gentle beasts had been facing extinction until the conservation authorities stepped in to protect and limit disturbances to the natural environment. As such, only small groups of tourists can observe the gorillas, and for only limited time periods. There are nine freestanding extinct and active volcanoes at Mgahinga Park that run along the borders of Rwanda and the Democratic Republic of Congo. Their movements influence the growth and availability of vegetation in the area, which in turn, affects the gorillas and their feeding habits. Bamboo shoots and broad-leaved forest montane offer staples to the gorilla diet. Other wildlife found in Mgahinga Park include Colobus and Golden Monkey, jackal, porcupine, Golden cat, giant forest hog, leopard, bushbuck, buffalo, honey badger, duiker, aardvark, and elephant.
