Gorilla Census in Bwindi

Gorilla Census in Bwindi

Bwindi Impenetrable National Park is Uganda’s treasured home of Mountain gorillas and a UNESCO World Heritage Site located in southwestern Uganda, consisting of tropical rainforest that is a sanctuary to the remaining mountain gorillas in the world. Bwindi Impenetrable National Park is one of the four regions where mountain gorillas can be found, along with Mgahinga Gorilla National Park, Volcanoes National Park in Rwanda, and Virunga National Park in the Democratic Republic of the Congo. The park’s Impenetrable forests, steep slopes, and rich biodiversity make it a unique and vital habitat for mountain gorillas.

The Park is also home to a variety of wildlife species, including Forest Elephants, buffalo, baboons, black and white-tailed monkeys, red colobus monkeys and over 450 bird species, including the African green broadbill, Grauer’s rush warbler, Shelley’s Crimsonwing, African emerald cuckoo, Handsome francolin, Black bee-eater, Western green tinkerbird, Kivu ground thrush, Dusky Crimsonwing, Rwenzori turaco, Blue-headed sunbird, Collared Apalis, Purple-breasted sunbird, Regal sunbird, Red-faced woodland warbler, Yellow-eyed black flycatcher, Bar-tailed trogon, White-bellied robin-chat and Red-throated alethe which make it a birding paradise.

The gorilla census has been conducted to monitor the population and health of these endangered species. The census of gorillas in Bwindi Impenetrable National Park was last conducted in 2018, and it included not just headcounts but also a comprehensive survey that provides invaluable data on the distribution of gorillas, social structure, and overall well-being.

How Many gorillas are in Bwindi?

Following the last gorilla census conducted in 2018, Bwindi Impenetrable National Park is inhabited by a total population of about 460 mountain gorillas, which makes up half of the world’s total mountain gorilla population. The gorilla census began around the 1960s, and an estimated total of 300 mountain gorillas was recovered in 1997. In 2002, the gorilla population moderately increased to 320 individuals. In 2006, the gorilla population increased to 340 mountain gorillas.

It is worth noting that due to continued conservation efforts and recent births recorded in the park, the population of these endangered species keeps increasing slightly, though diseases, poaching, and habitat loss are major threats to the existence of these fascinating creatures.

Methods used to count gorillas

Conducting a gorilla census in Bwindi Impenetrable National Park is a challenging experience. The dense forest, rugged terrain, and elusive nature of the gorillas require a well-coordinated and systematic approach.

Planning and Coordinating

Planning and coordinating are the first steps taken before the actual census begins, and this involves dividing the park into manageable sectors and assigning specific teams of trackers and researchers.

Tracking and observation

After dividing the park into different sectors, specific teams are allocated to each sector of the park in search of these endangered species. Once a group is located, researchers observe the gorillas from a safe distance to minimize the disturbance. They take recordings detailing the group’s composition, including the age, sex and any distinguishing features.

Data Collection

Researchers collect data on the number of nests, the size of dung piles, and the presence of silver hairs, which helps in identifying the age and sex of the gorillas. GPS coordinates are taken to map the exact location of each group. Data collection is crucial for understanding the location and movement patterns of the gorillas in their natural habitats.

Analysis and Reporting

After Data collection is done, researchers return and the headquarters and the data collected is gathered to estimate the total population, and make a final report about the health, distribution and number of gorillas counted. When the final report is done, the results are shared with the conservation organizations, the government and the public.

The significance of the gorilla census

Gorilla census is more than just headcounts, but also a critical tool of conservation that underpins every aspect of mountain gorilla protection and policy. Below are some of the reasons why the gorilla census is done;

Population monitoring: Knowing the actual number of gorillas in the park helps guide conservationists, the government, and international organizations to cater for these individuals with conservation methods that provide hope for steady increase and hope for the species once on the brink of extinction

Understanding group structure: Mountain gorillas in Bwindi live in social groups and are headed by dominant silverbacks, which helps the scientists to understand reproductive trends, infant survival rates, group stability and even inter-group relationships.

Health Assessment: Since these species are endangered and critically conserved, it is essential to assess their health issues, especially testing for pathogens, parasites and genetic diversity, which helps in detecting disease outbreaks such as Ebola or respiratory infections transmitted from humans.

Habitat Use and Movement Patterns: Since gorillas have a mobile nature, mapping their nests and GPS tracking helps to analyse how gorillas use their habitats as well as detecting their next movements, such as buffer zones or areas under encroachment that need urgent protection.

Conservation Planning: Knowing the total number of gorillas in the area helps in planning to conserve the right number, as well as implementing conservation policies and strategies.

Public awareness and Tourism: The existence of mountain gorillas in Bwindi, and having almost half of the total population in Bwindi Impenetrable National Park, often attracts media attention, thus drawing interest to come and see these species in their natural habitats, thus boosting the need for conservation and census, ensuring responsible ecotourism which is a key funding source for gorilla protection in Bwindi Impenetrable National Park and Mgahinga Gorilla National Park. Tourists want to visit places where their presence contributes to the real conservation success, and census data helps tell that conservation success story.

Conservation efforts for Gorillas in Bwindi Impenetrable National Park

The conservation of mountain gorillas in Bwindi Impenetrable National Park is one of Africa’s greatest environmental success stories. Despite being critically endangered animals, the gorilla population has steadily been increasing due to comprehensive conservation efforts, some of which include the following;

·       Community Involvement and Empowerment

·       Anti-poaching patrols and Law enforcement

·       Veterinary and Health Monitoring
