In their natural habitats of the tropical rain forests in Uganda, Rwanda, and Congo, the total mountain gorilla population is estimated to be 1, individuals. This is the highest population of mountain gorillas ever since their conservation started.
The total number of mountain gorillas left in the wild by is that from the last census in Bwindi Impenetrable National Park and Sarambwe forest reserve in With the several births in the habitats in the past years, the population has surely increased.
How many Mountain Gorillas are left in the wild in ? With their remaining numbers, it is popular to refer to the mountain gorilla population as endangered. However, previously the mountain gorillas were categorized as critically endangered because of their risk of extinction. With the increase in the number of mountain gorillas to over , they were moved from critically endangered to endangered. Since , when the mountain gorilla subspecies was discovered, the population has endured years of war, hunting, habitat destruction, and disease; threats so severe that it was once thought the mountain gorilla would be extinct by the end of the twentieth century.
However, what was seen as a population at severe risk saw a bright future a couple of years ago because of the increasing numbers. The Mountain gorilla population is distributed among the two natural habitats which are the Bwindi forest and Virunga massif. Bwindi Impenetrable National Park is situated in southwestern Uganda and is the single largest gorilla habitat.
They often get caught in snares laid out to trap other animals for bushmeat. Climate change also poses a threat: While gorillas are adaptive, moving to higher elevations to adapt to warmer temperatures, those areas are densely populated with little forest remaining. Catching illnesses from humans is also a threat. The majority of mountain gorillas are habituated to human presence because of the tourism industry, and while there are strict sanitation protocols in place and touching the gorillas is prohibited, disease could spread quickly.
The International Union for the Conservation of Nature, which sets the conservation status of species, changed their status from "crticially endangered" to "endangered" in as their numbers improved. Scientists, however, warn that they could quickly slip back into being critically endangered. To stay warm in the mountains, mountain gorillas have longer hair than their eastern lowland cousins, the Grauer's gorillas Gorilla beringei graueri.
They also tend to be a bit larger than other gorillas and have shorter arms. Gorillas can climb trees, but are usually found on the ground in communities of up to 30 individuals. These troops are organized according to fascinating social structures. Troops are led by one dominant, older adult male, often called a silverback because of the swath of silver hair that adorns his otherwise dark fur.
Troops also include several other young males, some females, and their offspring. The leader organizes troop activities like eating, nesting in leaves, and moving about in a home range of 0. Those who challenge this alpha male are apt to be cowed by impressive shows of physical power. He may stand upright, throw things, make aggressive charges, and pound his huge chest while barking out powerful hoots or unleashing a frightening roar.
Despite these displays and the animals' obvious physical power, gorillas are generally calm and nonaggressive unless they are disturbed. In the thick forests of central and west Africa, troops find plentiful food for their vegetarian diet. They eat roots, shoots, fruit, wild celery, and tree bark and pulp.
Female gorillas give birth to one infant after a pregnancy of nearly nine months. Unlike their powerful parents, newborns are tiny—weighing four pounds—and able only to cling to their mothers' fur. These infants ride on their mothers' backs from the age of four months through the first two or three years of their lives. Young gorillas, from three to six years old, remind human observers of children.
