*** I used the word 'bittersweet' earlier, because although intensive conservation measures have been a tremendous success for the preservation of Mountain gorillas, the parks where they live are in some of tropical Africa's most densely- populated regions: around the periphery of Bwindi Impenetrable National Park in Uganda for example, there are upwards of 300 people per square kilometer. The situation around Rwanda's Parc National des Volcans, is very similar. It follows that there is an urgent need to locate more land with viable tracts of habitat, while the Mountain gorilla numbers slowly continue to build up in the existing national parks where they find sanctuary.
