In the deep mountains of Hainan Island , the abundant sunshine and rainfall make the deep trees in the Bawang Ridge lush and the climate warm. This is a representative forest type of Asian tropical rainforest transitioning to evergreen broad-leaved forests. The fallen leaves that have been precipitated in the jungle for many years bring a soft and slippery area under your feet. The unique fragrance of soil in the jungle is also mixed with a trace of rotten air.
Compared with the reporters who came to participate in the Green Party, the national park staff walking in front of the team are obviously more familiar with the jungle.
Hainan Gibbon: 36 critically endangered species that exist in the world
Practice ecological civilization and promote harmonious coexistence between man and nature is an increasingly strong consensus among people in recent years. A year ago, the only tropical rainforest national park in the country was settled in Hainan. Now, this place has not only become a habitat for 14 national Class I protected wild animals, 7 national Class I protected plants, and 142 national Class II protected plants, but it has also become a business card for the national class I protected biodiversity .
In the lush national forest park, Hainan gibbons are undoubtedly one of the most popular "criminally endangered" species. In the narrow and ten square kilometers of Bawang Ridge, there are only 36 Hainan gibbons that remain in the world.
talks about the value of protecting these 36 gibbons. Zhong Yufei, deputy director of the Bawangling Branch of Hainan Tropical Rainforest National Park, said: "Hainan gibbons are very important for studying the origin of in humans. It has great scientific value. Its limbs, facial features, internal organs, blood, and production and metabolism are similar to humans, and its psychological, physiological and emotional aspects are very similar to humans. Therefore, protecting gibbons has a certain academic value for studying human evolution. ."
Hainan gibbons can reproduce on average 1 gibbon every 2 years, while underage gibbons have to wait 8-9 years to have fertility. Because the population size is too small, we cannot carry out artificial breeding. Therefore, the only way now is to protect them well and let Hainan's long arms reproduce and survive on their own. It has been more than 40 years since the development of 7-9 in the 1980s to the current 36. "We have no other choice. Protecting their homes is the most important task. We have expanded their habitat by more than 4,000 acres from 2003 to now."
uses digital technology to observe the long-armed monkey in real time 24 hours a day
Walking on Bawang Ridge until we get a lot of wet mud and fallen leaves under our feet, everyone really understands: patrolling the deep mountains of Bawang Ridge all year round and monitoring Hainan gibbons in traditional ways is not an easy thing. In addition to natural conditions such as difficulty in traveling on mountain roads, high temperatures and rainyness, and mosquito invasion, the more critical issue is efficiency.
Because Hainan gibbons are alert and live in trees all year round, it is very difficult to observe directly. They can only analyze their cry and make judgments. But collecting these sounds is difficult.
Hainan Gibbon Monitoring Team member Wei Fuliang said: "Our monitoring team members have to get up very early. If it is early, for example, in summer, we even need to go to the monitoring site before dawn. We cannot see it by going up, and it also depends on luck. Maybe when we call today, our monitor is far away from it. It calls for more than ten minutes. We stopped calling before we arrive. It is difficult to find it."
More than ten employees in the entire Gibbon activity area, in addition to protecting Gibbons, there are also heavy work of forest fire prevention , pest control and other work. The same monitoring site can only come back every 3 months on average, and the monitoring equipment can only store information for about 15 days. This means that the monitoring equipment of the entire Bawang Ridge cannot collect sound normally for more than 80% of the time, which also brings great difficulties to the protection of endangered animals.
Huawei , in conjunction with IUCN ( World Union for Conservation of Nature ), and Hainan Tropical Rainforest Research Institute jointly launched a pilot project called Tech4Nature.
Zheng Xiaping, chief architect of Huawei's natural resources field, said: "The core goal of the project is to use advanced digital technology to protect the ecology, and achieve 24-hour real-time monitoring of gibbons through networked sound equipment. This has enabled the staff in the national park to improve the information collection ability of several times."

listen to the ape sound to identify individuals, and technology protects nature
"Take the sound materials back is the first step. Listening so many materials is really a waste of effort." The staff told us.
In the past, listening to sounds to identify the sounds of gibbons was a simple but boring job. If you are not careful, you may miss important information. You can also have a fast forward function when watching the screen, but you can only listen to the audio honestly. Sometimes, in order to confirm a detail, it takes much longer to listen to a piece of sound than the audio material itself.
Professor Fan Pengfei from , Sun Yat-sen University, achieved an accuracy of 89.2% of individual recognition of audio materials through a series of algorithms and model fitting, helping environmental experts to more accurately judge the member composition of the gibbon family. Next, based on Huawei's AI framework, a machine recognition of the ape sound can be realized and a unique "voice ID card" can be established for each gibbon. The large amount of collected data is sorted and automatically classified, which can dynamic changes in the structure of the gibbon family and can maintain long-term tracking.
"Technology protects nature, technology is a tool, and in the end it depends on our people. In fact, there is a very good boundary between people and nature. We may not necessarily break through this boundary, but silently protect this boundary. Whether it is a big forest, a river, or a nature, it is a barrier, and it is also our common home." In the end, Liu Jingyang, Minister of China Media Affairs of Huawei, said.
