Introduction:

Name: Delacour's Langur Scientific name: Trachypithecus delacour

Common name:

Delacour’s Langurs, White – Rumped Black Leaf Monkey.

Kingdom Phylum Class Order Family ANIMALIA CHORDATA MAMMALIA PRIMATES CERCOPITHECIDAE

The Delacour’s langur is a Critically Endangered species, because there are less than 250 in its population.

The Delacour’s Langurs is black with white ‘’pants’’, whitish-grey cheeks ,and a erected crest on the head; very bushy tail. His tail is around 1-1.5m long, and bushy. His adult weight is around 6 kilograms. This species eat only leaves and sometimes potato. This species also have a good balance. Because when I was obviate him he was sleeping on a little branch. They have only 4 finger and 4 toe. He was really quiet he didn’t make any sound.

Observations of primate:

This species’ natural habitat is presently restricted to limestone karst forest habitat in Central North Vietnam, with some records from secondary forest in limestone areas as well. They live in the rain forest and in the cave. They live in the cave because they can be protect from the predator and they can have extremes temperature. But they only live in the cave the night or when there is a predator. The day, they live in the tree. There habitually live in 1000 m high in the tree. The animals adaptation in captivity it’s good and bad. It is good because they can reproduce easier, because in each cage there is one Male and on Female. It is also bad because they do not learn to defend themselves and hunt like in the wild.

Endangerment and Conservation: This species is in danger because the people hunt it. They hunt the delacour’s langur because they use its parts and meat for medicine and food. This species is also in danger because of Forest loss and degradation, illegal grazing of goats. A potential threat in the future is tourism associated development. The human impact on this species is both negative and positive. Humans have created protected areas for the primate. The humans have also built special rescue centers, with the goal of saving endangered primates. Other positive humans actions includes adding the Delacour’s Langurs to the endangered list, protecting them by law. The negative human actions include keeping animals as pets, limestone quarrying, deforestation, hunting, illegal grazing of livestock.

Because the humans are motivated by money, most of the negative actions listed above are done to earn a living. So I think we can make a solution to give them better ways to earn money. For example planting café or rice etc.

It can cause problems maybe because in order to plant rice or cafe we need space, so we cut down trees to make room, or maybe because they can earn less money doing these jobs. This relate to criterion D2 its all of the factors, because socially it’s change how do they live because maybe they have to go somewhere else, economically because it change the way they get money, politically because we have to convince them to change their economic model, and environmentally, because it affect the way the tree are cut and the primate are hunt.

Conclusion I think we should save the primates that have more than 100 population because I this it will be to difficult to save the primates that have less than 50 populations. l think some humans try to do they best to save the primate but I think they can’t save all of them. For example the Cao-Vit or Eastern black- crested gibbon (Feared extinct until a survey rediscovered a population in the limestone forest of Phong Nam-Ngoc Khe Communes) have less chance than the Grey-shanked douc monkey (Population: 600– 700 individuals).

So Yes I think is important to save my primate because there is less than 250 populations. Because we could have more chance to save it.

If there will be no more delacour’s lungurs, there will be no more medicine ( maybe we can do a special medicine with this species), no more delacour’s langurs meat(food), and maybe there is no more Delacour’s langurs because the hunter kill all of them then there will have no more job(because maybe there just hunt the delacour’s langurs), or maybe is because we cut to mush tree, then they will have to go to a other place to continue they job.
