Item Census of the mountain gorilla Gorilla beringei beringei population in Bwindi Impenetrable National Park, Uganda(Oryx, 2006) McNeilage, Alastair; Robbins, Martha M.; Gray, Maryke; Olupot, William; Babaasa, Dennis; Bitariho, Robert; Kasangaki, Aventino; Rainer, Helga; Asuma, Steven; Mugiri, Ghad; Baker, JuliaMountain gorillas Gorilla beringei beringei are Critically Endangered, with just two small populations: in Bwindi Impenetrable National Park in south-western Uganda and the nearby Virunga Volcanoes on the borders with Rwanda and Uganda. A survey of the Bwindi population was carried out in 2002 and results were compared with the previous census in 1997. Our estimate of total population size increased over that period by c. 7% to 320 individuals and the structure and distribution of the population were largely unchanged. Signs of human disturbance were more common in 2002 than 1997, and gorillas tended to be found in areas of relative low disturbance. This suggested that disturbance could be a constraint on population growth and distribution but demographic stochasticity may also be responsible for the observed level of population change over a short time period. Other potential limiting factors, including habitat availability and disease, are discussed. While conservation activities in Bwindi have probably contributed to the stability of the population, strengthening of law enforcement and continued vigilance are needed to ensure the population’s long-term growth and survivalItem A Survey of Burnt Areas in Bwindi Impenetrable and Mgahinga Gorilla National Parks, S. W. Uganda The Fires Of 2000(Institute of Tropical Forest Conservation, 2001) Kasangaki, Aventino; Babaasa, Dennis; Bitariho, Robert; Mugiri, GhadFire has been one of the main management challenges and is considered one of the major long-term threats to forest biodiversity in Bwindi Impenetrable and Mgahinga Gorilla National Parks. In June, July and August 2000 fire outbreaks occurred the two parks. During September 2000 we carried out a survey of the burnt areas, which aimed at documenting the burnt sites and extent of damage caused by the fires. This was done as part of a long term monitoring programme to advise park managers about what could be done to prevent, halt or decrease incidences of fire outbreaks. The results show that approximately 0.2 square kilometers constituting 0.05% of the total park area was affected by fire in Bwindi Impenetrable National Park. The area affected was significantly smaller than that burnt in 1999 (2.64 square kilometers, 0.8% of park area); there has been a significant reduction in fire incidences in Bwindi in 2000 that we have attributed to the difference in the number of ‘rainy days’ in the ‘North sector’ and Buhoma and Ruhija, improved park boundary maintenance and increased sensitization of communities surrounding the park. However, the total numbers of ‘rainy days’ during the months of May to September were not significantly different between 1999 (139 ‘rainy days’) and 2000 (127 ‘rainy days’). In Mgahinga Gorilla National Park, 0.1 square kilometers constituting 0.3% of the Park area was affected by fire. However, we have no previous with which to compare 5 these estimates. In both parks illegal honey collectors caused most fires with a few spreading from community agricultural fields. On a positive note, the communities’ response to putting out fires was almost 100%. This shows an improved attitude of the communities towards protected areas. Given the fact that fire has become a regular component of the disturbance regime in the two parks, we recommend preventive measures such as public education and good public relations between parks and local communities, instituting and enforcing legislation on regulations for lighting fire in the park, establishment of early warning systems and the establishment and maintenance of a clear park boundary. We further advocate for the provision and maintenance of appropriate equipment and training of park staff in fire suppression measures. Lastly, since illegal honey collectors caused most fires, we recommend that park staff and all stakeholders in the management of the two Parks intensify sensitization of the communities on the dangers of fire in protected areas.
