Besides the killing of Rafiki, poachers in recent weeks have mostly hunted smaller animals, such as antelope, probably to eat them rather than for trading.
A 25-year-old male gorilla named Rafiki was found dead in June at the Bwindi National Park in Uganda.
A Ugandan man who pleaded guilty to killing a rare silverback gorilla was condemned to 11 years in prison on Thursday.
The poacher admitted to going hunting in the park but claimed he had killed Rafiki in self-defence after the silverback charged at the hunting party. Rafiki had experienced justice.
Byamukama Felix was arrested a few days after Rafiki's body was found with bush pig meat and several hunting devices on hand, authorities said. A post-mortem report later said a sharp objected had penetrated Rafiki's internal organs, causing its death.
The Chief Magistrate His Worship Julius Borere sentenced him to 5, 6, and 5 years respectively to be served concurrently.
"Rafiki has received justice", the Uganda Wildlife Authority said, the BBC reported.
3 other males who were being arrested with Felix continue to be in custody awaiting trial as they have pleaded not responsible.
'If one person kills wildlife we all lose, therefore we request every person to support our efforts of conserving wildlife for the present and future generations'.
Mr Mwandha further said the new Wildlife Act 2019 is tough and that anyone involved in illegal wildlife activities would face the law.
The mountain gorillas are a popular draw for visitors to the country, helping boost tourism revenue that the UWA relies on. The approximately 400 mountain gorillas living there are used to humans.
The team was the to start with to reside in the southern part of the park that is dwelling to about half of the world's mountain gorilla populace.
Poaching is rampant in Uganda's game parks and police frequently announce seizures of illicitly acquired wildlife products such as ivory, rhino horns, pangolin scales and others.
