PHNOM PENH (AFP) — One-time hunters recruited to a conservation project have helped threatened bird populations in Cambodia's Great Lake recover, according to a report Friday.
The Wildlife Conservation Society (WCS) report said populations of some of the bird species had increased 20-fold since the project began in 2001 at Tonle Sap Lake, known as the Great Lake.
The project by the WCS and Cambodia's environment ministry employed about 30 former hunters and egg collectors as park rangers tasked with providing 24-hour protection for breeding colonies, the report said.
The plan was to boost the populations of the spot-billed pelican, milky stork, painted stork, lesser adjutant, greater adjutant, black-headed ibis and the Oriental darter.
The waterbird colonies were first discovered in the mid-1990s. At the time, the birds were threatened with extinction because of villagers' rampant harvesting of eggs and chicks, the report said.
"When first discovered, the colonies were heavily threatened by annual harvesting of the eggs and chicks by nearby villagers, mainly for trade and local consumption," the report said.
But the populations of the birds have increased from a total of 2,500 breeding pairs in 2001 to more than 10,000 pairs in 2007.
The colonies include the largest, and in some cases, the only breeding populations for the waterbirds in Southeast Asia, according to the report.
Tonle Sap lake is Southeast Asia's largest freshwater reservoir, which can expand to 12,000 square kilometres at the peak of the rainy season and recedes to about 3,000 square kilometres in the dry season.
The lake is rich in biodiversity and offers a breeding place for many species of birds and fish.
