| The black leaf monkey, one of the most endangered primates in the world, turned out to be golden when he was a child |
According to the latest release issued by the National Forestry and Grass Administration, in recent years, with the strengthening of protection in China, the conditions for the reproduction and reproduction of the black leaf monkey have been continuously improved.
Not only has the core population been effectively protected, but also its habitat is gradually expanding
.
Conservation of black langurs in my country is effective
Conservation of black langurs in my country is effective In 2018, a new wild population of black langurs was discovered in Qinglong County, Guizhou Province.
The population of black langurs in nature reserves such as Mayang River and Jinfo Mountain also spread outside the protected areas, and the habitat area of black langurs has increased to a certain extent.
Increase
.
The black leaf monkey is a national first-class protected animal and one of the most endangered primates in the world
.
At present, it is only distributed in China and Vietnam in the world, and more than 90% of the population is distributed in China
The black leaf monkey is a national first-class protected animal and one of the most endangered primates in the world
Deng Huaiqing, professor of the School of Life Sciences, Guizhou Normal University:
In order to protect the black leaf monkey and its habitat, China established the Mayang River Nature Reserve in Guizhou in 1987 and was promoted to a national nature reserve in 2003
.
In recent years, Guizhou’s Mayang River National Nature Reserve has strengthened its protection in all aspects, strictly controlled human activities in the black langur activity area, and continued to increase patrols.
The population of black langurs in this area has been effectively protected and protected.
Resume
.
At present, the Mayang River National Nature Reserve in Guizhou is the area with the most concentrated and largest populations of black langur populations in the world
Yang Chaohui, person in charge of Liangqiao Station in Mayang River National Nature Reserve: In addition, we have also strengthened the scientific research and protection of black langurs.
Through these measures, the population of black langurs in the reserve has gradually increased
.
According to statistics from relevant departments, as of now, the number of black langurs in Guizhou and Chongqing has increased significantly, reaching more than 1,100 and nearly 200 respectively
.
In particular, Guizhou’s Mayang River Nature Reserve has grown from more than 380 at the beginning of its establishment to 580, Kuankuoshui Nature Reserve has grown from more than 130 to more than 190, and Chongqing Jinfo Mountain Nature Reserve has grown to more than 150.
The restoration of the black langur population also shows that the trend of karst rocky desertification in southwest China has been effectively curbed, and the ecological environment of the karst area has been restored to a certain extent

Reporter visits the "Black Elf" kingdom in the wild
Reporter visits the "Black Elf" kingdom in the wild The black langur is a typical social animal, which is different from the large group of primates such as golden monkeys and macaques, which are composed of several families.
The black langur monkey group is a single family unit, generally only 3-15
.
In Guizhou’s Mayang River National Nature Reserve, there are 72 groups of more than 580 animals living here, so the reserve is also known as the "Kingdom of the Black Leaf Monkey"
.
A few days ago, the reporter followed the experts to the reserve and visited the kingdom of the "black elves"
The Mayang River National Nature Reserve is a rocky mountain composed of karst landforms, dense virgin forests, and banded steep rock walls, creating the best place for black langurs to inhabit
.
The reporter walked along the dangerous sidewalk along the Mayang River valley.
Two black langurs sitting on the side of the road instantly attracted everyone's attention
.
As a family social animal, experts judged that there must be other family members nearby
Deng Huaiqing, a professor at the School of Life Sciences, Guizhou Normal University: The family of black leaf monkeys is generally composed of a family structure of one male and multiple females.
There are also some young individuals and juvenile individuals, which form a separate family group.
Generally, they are not distributed in the same area
.
Suddenly, a strange sound came from the tree, confirming everyone's judgment
.
The reporter clearly saw several black shadows jumping up and down among the trees
Deng Huaiqing, a professor at the School of Life Sciences, Guizhou Normal University: This must be a new-born baby monkey.
Under normal circumstances, the whole body of the new born monkey should be golden yellow.
It will turn black after one month, and basically all become the same color as an adult after six months.
It hasn't changed completely yet, so it looks like only three to four months after it was born
.
Deng Huaiqing told reporters that the reproduction rate of black langurs is very low.
The same female black langur will give birth to one cub in one to two years
.
Therefore, every newborn monkey in the population will be cared for by family members in every possible way
Deng Huaiqing, a professor at the School of Life Sciences, Guizhou Normal University: A baby monkey will receive all the care and love in the group after it is born.
In addition to its mother, other adults and young individuals will take care of it.
Among them is the most protected baby
.
At the beginning of this year, in the Mayang River National Nature Reserve, four baby monkeys were born one after another in the same group of monkeys.
This situation is very rare
.
Xiao Zhijin, a forest ranger in Mayanghe National Nature Reserve: The four baby monkeys born from January to February this year are very cute.
You see, they are breastfeeding
.
At present, the four baby monkeys have gradually grown up under the careful care of family members
.
Xiao Zhijin, a forest ranger in the Mayang River National Nature Reserve: You see these monkeys are quite lively.
Basically, they have all turned black and look very healthy
.
The black leaf monkey is different from other common arboreal primates.
The black leaf monkey feeds and lives in the forest during the day and stays in the cave at night
.
The reporter followed the expert and visited the home of the black langur family that was born with four baby monkeys
.
Deng Huaiqing, a professor at the School of Life Sciences, Guizhou Normal University: This monkey group is a relatively large and special monkey group.
The Monkey King Cave it lives in is also the largest cave among the known overnight places
.
The reporter saw on the scene that the "Monkey King Cave" is a typical karst cave with an opening of about 20 meters wide and about 15 meters high.
The cave is about the size of two basketball courts.
The strange rocks hanging from the top of the cave are formed by each other.
Stone seam, this is the "home" of the black leaf monkey
.
Deng Huaiqing, a professor at the School of Life Sciences, Guizhou Normal University: All the caves in which the black langurs live are naturally formed, and they are also unique caves in the southern karst area of our side.
This is why the black langurs are only distributed in karst areas
.
In the Monkey King Cave, experts found many traces of the habitation of black langurs
.
.
Deng Huaiqing, a professor at the School of Life Sciences, Guizhou Normal University: The black leaf monkey is a relatively clean animal, so when it defecates and urinates at night, it has to go to the mouth of the hole to be discharged outside, then in the process of being discharged outside, it flows down from the mouth of the hole, so The cave it lives in has this kind of yellow trace.
This is the trace left by its excrement.
When we see such a hole, we can judge that it has lived here
.
After careful observation of the environment in the cave, experts determined that this large family of black langurs had moved
.
Deng Huaiqing, a professor at the School of Life Sciences, Guizhou Normal University: This has no fresh feces, which means that it has not been active here for at least two or three months.
We also know that a group of monkeys have several nights, and they have the habit of changing nights.
.
Xiao Zhijin: A person who can talk to the "black elves"
Xiao Zhijin: Xiao Zhijin, a forest ranger in the Mayang River National Nature Reserve in Guizhou Province, is 59 years old this year.
He can call out black langurs from the depths of the forest
.
From the last century eighty-nine beginning 1980s, rain or shine, he guarded the black elves thrive from generation to generation
.
Century eighty-nine 1980s, to protect langurs, explore the establishment of artificial intervention, Mayang River National Nature Reserve to carry out artificial feeding domesticated wild langurs project
.
As a forest ranger, Xiao Zhijin participated in the project, which required him to have a good knowledge of the life habits of the black leaf monkey
.
Xiao Zhijin, a forest ranger in the Mayang River National Nature Reserve: The whole process of feeding and domestication was difficult at first.
Every morning, he would run to the entrance of the cave before dawn and put food for it, and always observe that it can eat.
.
The black langur is alert by nature, hides when it sees people, and runs away when listening to the whistle
.
In order to understand the living habits of the black leaf monkey, Xiao Zhijin insisted on staying in the cave every day for a long time
.
From the initial concealed feeding, to guiding feeding, and now as long as the whistle sounds, the black langurs on both sides of the Mayang River will hear the sound, and take food from him one by one.
This seems simple It took Xiao Zhijin several years to succeed in the feeding action of "feeding in his hands"
.
So far, he clearly remembers the first time the monkeys approached him
.
Xiao Zhijin, a forest ranger in Mayang River National Nature Reserve: The first close contact was on the morning of the first day of the first lunar month in 1989.
When I went to feed, the three whistles sounded and the monkeys were from the Monkey King.
I ran to the river dam at the entrance of the cave.
I was very excited at that time, and I was very happy in my heart
.
Today, there are 72 groups of more than 580 black langurs living in the Mayang River National Nature Reserve, accounting for one third of the global population
.
In the deep mountains of the reserve, Xiao Zhijin has been guarding this group of endangered black elves for decades.
The longer the time, the deeper his feelings
.
Forester Xiao Zhijin of Mayang River National Nature Reserve: My relationship with the black leaf monkey is like the relationship between me and my children.
I love it, care about it, and do my part to protect it
.
Xiao Zhijin is 59 years old this year and will retire next year.
He has too much regret
.
Forest Ranger Xiao Zhijin of Mayang River National Nature Reserve: Even if he is about to retire, I hope to extend it for another five or ten years.
Especially the black leaf monkey has formed a deep relationship with me.
I can't bear it, I have the ability.
Under the circumstances, willing to pay for them again
.
