Current Population Status of Primates
The population of primates worldwide has been significantly impacted by various factors such as habitat loss, deforestation, hunting, and illegal wildlife trade. This article aims to provide an overview of the current population status of certain primate species based on available data from reputable sources.
Hainan Black Crested Gibbon (Nomascus hainanus)
The Hainan Black Crested Gibbon is a critically endangered primate species found in China. According to estimates, the population of this species is estimated to be between 20 and 50 individuals [1].
Eastern Black Crested Gibbon (Nomascus nasutus)
The Eastern Black Crested Gibbon was previously believed to be possibly extinct. However, recent estimates suggest a population of 45 to 47 individuals, highlighting its critically endangered status [1].
Cat Ba Langur (Trachypithecus poliocephalus)
The Cat Ba Langur, endemic to Cat Ba Island in Vietnam, faces a precarious situation. Its population is estimated to be between 51 and 54 individuals, making it one of the most critically endangered primate species [1].
Popa Langur (Trachypithecus popa)
The Popa Langur, native to Myanmar, has a population estimated to be between 135 and 176 individuals. Its conservation status is listed as critically endangered due to habitat loss and hunting [1].
Raffles’ Banded Langur (Presbytis femoralis)
The Raffles’ Banded Langur, found in Singapore and Malaysia, has a population estimated to be between 200 and 250 individuals. It is classified as critically endangered due to habitat fragmentation and poaching [1].
Sarawak Surili (Presbytis chrysomelas)
The Sarawak Surili, endemic to Borneo, has a population estimated to be between 200 and 500 individuals. This species is listed as critically endangered, primarily due to habitat loss and illegal hunting [1].
Perrier’s Sifaka (Propithecus perrieri)
The Perrier’s Sifaka, native to Madagascar, is one of the 25 most endangered primate species. Its population is estimated to be 230 individuals, highlighting the urgent need for conservation efforts [1].
Delacour’s Langur (Trachypithecus delacouri)
The Delacour’s Langur has experienced a radical decrease in population over the past decade. Unfortunately, specific population estimates are currently unavailable, but this species is critically endangered [1].
Silky Sifaka (Propithecus candidus)
The Silky Sifaka, found in Madagascar, has a population estimated to be around 250 individuals. However, it is important to note that this estimate is believed to be a maximum estimate, and the actual population could be lower [1].
Tonkin Snub-nosed Monkey (Rhinopithecus avunculus)
The Tonkin Snub-nosed Monkey, endemic to Vietnam, has a population estimated to be around 250 individuals. This species is critically endangered, primarily due to habitat loss and hunting [1].
It is crucial to prioritize the conservation of these primate species by implementing effective measures to protect their habitats, combat wildlife trafficking, and raise awareness about their ecological importance. Further research and conservation efforts are necessary to ensure the survival of these endangered primates.
