Countries in West Africa have been urged to conduct investigations into the money-laundering activities of wildlife traffickers.
A new report by the Royal United Services Institute, a London-based think tank, has warned that criminals in the wildlife trade have relocated to West Africa from other parts of the continent
This is in order to take advantage of weak law enforcement and a lack of investigations, the report says.
In the last few years West Africa has become a major transit point for illegal trade in wildlife - including elephant tusks poached elsewhere in Africa as well as pangolins.
In 2019 51 tonnes of pangolin scales were exported through Nigeria alone.
The country has been identified as the top transit point for illegal wildlife trade in the region.
The Ugandan authorities have arrested four people suspected of killing six lions in one of the country's most famous parks.
The lions were found dead and mutilated last Friday and their bodies surrounded by dead vultures in Queen Elizabeth National Park.
On Tuesday, the Uganda Wildlife Authority (UWA) said the suspects were arrested in a joint operation by the military, police and the wildlife authorities.
"Today at daybreak, the suspects took the security team to a location where three heads of lions were found hidden in a tree and the fourth one was buried with 15 legs under the same tree. The suspects said they dropped one leg in the park," the UWA said in a statement.
The authorities did not give an indication about why the lions were killed.
The wildlife authority said they found a bottle of a poisonous chemical and a jerrycan of lion fat at a banana plantation. It also found two spears, a machete and a hunting net with one of the suspects.
It said the operation had began after they received "credible information" about the suspects.
The authority had on Monday offered a cash reward of 10m shillings (about $2,725; £1,987) for leads to the suspects.
Last week, the UWA said it had been "saddened" by the killing of the lions - which are particularly known for their ability to climb trees.
A Kenyan man has pleaded not guilty in an American court to trafficking ivory and rhino horns worth millions of dollars.
He also denied charges of money laundering and drug dealing and was detained without bail, the Associated Press news agency adds.
US federal prosecutors say the suspect, Mansur Mohamed Surur, was part of an international conspiracy that was responsible for the slaughter of more than 100 elephants and dozens of rhinos.
Mr Surur was extradited from Kenya and arrived in the US on Monday to stand trial. He was arrested last year in the Kenyan city of Mombasa.
He and three others from Guinea, Liberia and Kenya are accused of agreeing illegal sales with buyers in Manhattan, as well as others in South East Asia.
US attorney Audrey Strauss said Mr Surur was involved in the illegal poaching of approximately 35 rhinoceros and more than 100 elephants.

Six young Mozambican men have been shot dead this year in South Africa's Kruger National Park, an official in Mozambique says.
The men, all from Mozambique’s Massingir district which borders the park, were suspected of being poachers.
Last year, at least nine suspected poachers from Massingir were killed in the park, one of the world's most famous game reserves.
Hundreds of wild animals are poached there every year, especially rhinos whose horns are highly valued in parts of Asia.
Mozambique’s authorities were working with the local community to try to dissuade young people from poaching, Massingir district administrator Sergio Moyane said.
