Mountain Gorilla: A Shattered Kingdom [Full Documentary] | Wild Things

This extraordinary portrait of a group of wild gorillas is a family saga rich in the grand themes of any human drama – death, adolescent rebellion, jealousy and parenthood.

Obtaining sodium likely creates an incentive for the gorillas to leave park areas and make forays into high-altitude habitat. Both locations are not without risks: exiting their natural habitat and feeding on crops may increase human-wildlife conflict and visiting high-altitude areas may increase the risk of hypothermia.
The results may advance the discussion of how to adapt local human land use to effectively curb human-wildlife conflict.
“When gorillas raid eucalyptus stands outside the national park, they come in contact with local inhabitants, which puts both ape and human at risk. To discourage the gorillas from crossing into farmlands near the forest, agricultural practices may need to be reconsidered”, said lead author Dr. Cyril Grueter, of The University of Western Australia, in Perth. “Ideally one would want to favor plant species that are nutritionally unattractive to the gorillas.”

Fossey, alarmed by poaching and deforestation, predicted the species could be extinct by 2000. But a sustained conservation campaign has averted the worst. [AP]
