Trentham Monkey ForestCrinkle, from Stoke-on-Trent, has been central to the projectResearchers say they have achieved a "world first" by successfully mapping the DNA of a monkey in Staffordshire.
The groundbreaking genome sequencing is from a Barbary macaque called Crinkle at Trentham Monkey Forest, Stoke-on-Trent.
Those behind the research said it gave them a "powerful new weapon in the fight against extinction".
Monkey Forest park director Matt Lovatt said: "Knowing that her DNA could help protect Barbary macaques from poaching and illegal trade is something truly special."
Scientists said Crinkle had become the first of her species, which is endangered in the wild, to have her complete genetic code decoded.
They added it could "change conservation forever", as until now they had not held a complete genetic reference for Barbary macaques.
This made it difficult to track populations, understand their genetic health, or identify where trafficked animals were stolen from.
Trentham Monkey ForestCrinkle's DNA could help protect Barbary macaques from poaching and illegal tradeUsing the new information, described as a "master key", those involved in the project said they had already traced Crinkle's roots back to wild populations near Ifrane National Park and Khenifra National Park in Morocco - two strongholds for the species.
"We're incredibly proud that a Barbary macaque from Trentham Monkey Forest is at the heart of such a groundbreaking scientific achievement," said Lovatt.
"Crinkle represents not just our forest, but a species facing real threats in the wild."
Trentham Monkey ForestCrinkle is one of about 140 monkeys at Trentham Monkey Forest in Stoke-on-TrentDr Patrick Tkaczynski from Liverpool John Moores University was also involved in the research.
He said Barbary macaques used to be found all around the Mediterranean, but were now isolated to a few pockets across North Africa and Gibraltar.
"If this kind of science can help identify where trafficked animals have been taken from, it becomes a powerful tool in the fight against wildlife crime," Lovatt added.
"Ultimately, it gives us a better chance of protecting these incredible monkeys in the wild."
