MOUNTAIN GORILLA CENSUS SET FOR SEPTEMBER IN VIRUNGA MASSIF
A new census of the mountain gorilla population in the Great Virunga Massif is set for September, 2015 the Greater Virunga Trans boundary Collaboration- GVTC has said.
The massif includes Uganda's Bwindi and Mgahinga National Park, Virunga National Park in DR Congo and the Volcanoes National Park in Rwanda.
With the last census conducted in 2010, other censuses have been conducted in 2006, 2002 and 1997. The last figures showed that the three countries have a population of 880 Gorillas, with more than half of them in Uganda.
James Byamukama, the Programme Manager at GVTC says the exercise, which should have started earlier, was delayed by the insecurity in DR Congo. He however adds that they are set to conduct the census in September starting in Virunga National Park.
Byamukama says with the census, the collaboration will be able to plan for future conservation efforts and the emerging trends of threats to gorilla population.
Aggrey Rwethsiba, the Senior Monitoring and Research Coordinator at Uganda Wildlife Authority, says f***l samples and DNA analysis will be the key method used to determine the numbers.
For the past Gorilla censuses, they depended on the sweep method, where teams traverse each marked sector of the park in a zigzag manner looking for fresh gorilla trails till their nests are found and counted. But Rwethsiba says the system was not effective because it created incidences of double counting and underestimation in some cases.
Rwetshiba says since 1997, the number of the gorillas has been increasing. He says currently Bwindi alone has about 400 Gorillas and the Virunga that includes Volcano National Park in Rwanda, Mgahinga National Park in Uganda and Virunga in DRC has about 470 mountain gorillas.
He says Mgahinga has an estimated number of 37 gorillas, resident while the rest move between the three countries.
Mountain gorillas stand out from the three other gorilla subspecies because of their thick coats, which insulates them from the cold of their cloud forest homes. There are only two places on Earth where mountain gorillas exist: Bwindi Impenetrable National Park and the Virunga Volcanoes in the equatorial African nations of Uganda, Rwanda, and the Democratic Republic of Congo.
Though gorillas have few natural predators, they are endangered due to the loss of habitat and forest clearing. They also fall victim to hunting for the wildlife trade, and through accidental snaring by poachers who are targeting antelopes for meat. Diseases that affect humans also pose a threat to apes and can spread quickly in such small populations.
