Kaçak avcılık ve hayvanların habitatlarının yok edilmesi nedeniyle, doğu gorili nüfusunun son 20 yılda yüzde 77 azaldığı belirtildi.
Found in the Republic of the Congo, northwest of Rwanda, and southwest of Uganda, the eastern gorilla has two subspecies: the Grauer gorilla and the Beringei gorilla.
The population of Grauer gorillas was 16,900 in 1994. In 2015, it was stated that this number decreased to 3 thousand 800.
Of the Beringei gorillas, only 880 survive.
