XINING－For the past decade, Tibetan ranger Gechok has typically started his day with the same routine, waking up in the early morning and riding on horseback to the source region of the Yellow River.

He spends seven hours a day on patrol, covering dozens of kilometers, taking notes on the occurrence and activities of wild animals, vegetation growth and changes to the snow line. The details are jotted in a notebook and then collated, before being sent in reports to environmental protection professionals.

"Previously, the animals and plants were just scenery to me. But when I became a ranger, I learned the recording methods from professionals, and realized that these are scientific research materials, which can be used to better protect the ecological environment," he said.

Gechok is among over 20,000 herders who have secured new jobs as rangers in Sanjiangyuan National Park in Northwest China's Qinghai province, which sits at an average altitude of more than 4,700 meters.

The Sanjiangyuan area is known as Asia's "water tower" as it contains the headwaters of the Yangtze, Yellow and Lancang rivers. It is also home to nearly 70 wildlife species under State protection, accounting for 26.8 percent of China's total national protected species.

Previously, due to climate change and various human activities, Sanjiangyuan suffered serious ecological degradation, with a large number of lakes disappearing and wildlife declining sharply.

In recent years, however, the situation has been largely improved, with concerted and unremitting efforts made by governments at various levels, institutes and grassroots workers.

Continuous efforts

Madoi county in Qinghai's Golog Tibetan autonomous prefecture, where the Yellow River source region is located, has witnessed changes in its ecological environment over the years.

From the 1960s to the 1980s, Madoi's main industry was animal husbandry.

At that time, each household in the county possessed hundreds of cattle and sheep, and the development of animal husbandry boosted the local economy.

In the early 1980s, Madoi became one of China's richest counties in terms of animal husbandry.

However, from the late 1980s to the beginning of this century, due to various factors, including climate change, the wetlands and lakes in Madoi decreased, grassland vegetation degraded, the water conservation capacity dropped sharply, biodiversity was impacted, and local economic and social development was hampered.

The headwaters of the Yellow River in Madoi partially dried up between 2003 and 2004, exposing river beds covered in yellow sand.

To restore the ecological environment, the county government has taken a series of measures, including initiating ecological migration programs, imposing a grazing ban in certain areas, and encouraging local herders to participate in ecological protection.

The measures have proven effective, with the trend of deterioration in the local ecology reversed.

Madoi is a fine example of China's efforts at improving the ecological environment and biodiversity in the Sanjiangyuan area.

Sun Lijun, deputy director of the Sanjiangyuan National Park administration, said that starting in 2005, China launched ecological projects to protect and restore the environment in Sanjiangyuan, with an accumulated investment of more than 22 billion yuan ($3.19 billion).

In 2016, China started piloting the Sanjiangyuan National Park. Each household living inside the 190,700-square-kilometer park was offered a job as a ranger with an annual income of over 21,000 yuan.

In addition to these efforts, many counties and townships in Sanjiangyuan began to explore their own environmentally sustainable development models based on their respective characteristics.

The Namse township in Qinghai's Yushu Tibetan autonomous prefecture, through which the Lancang River flows, is known as the "hometown of snow leopards" due to the frequent sightings of the big cat species.

Starting in 2019, the township piloted a franchise business model for tourism, training some herders to serve as ecological guides to host tourists. Currently, Namse's Nyanthok village has more than 10 such guides, with each household earning more than 10,000 yuan annually.

Last October, the Sanjiangyuan National Park was officially designated.

Positive signs

Years of unrelenting conservation efforts have yielded positive results.

"The Yellow River's headwaters have kept flowing for nearly 16 years," said Gan Xuebin, deputy director of the management bureau of the Yellow River's headwaters region of the park.

Gan added that the number of lakes in Madoi, dubbed "the county of a thousand lakes", increased from the 4,077 recorded in the county annals to 5,849 in 2018, while 104 sq km of wetland was newly added by 2018.

According to a news briefing held Wednesday in Qinghai, over the past decade, water conservation in the Sanjiangyuan area has risen by over 6 percent on average each year, while grassland coverage has increased over 11 percent and grass output increased 30 percent.

Amid efforts to improve wildlife habitats and conserve ecosystems, the populations of wild animals and plants have continued to increase in the Sanjiangyuan area.

Karma Yingphel, who works at a protection station in Sanjiangyuan National Park, has been patrolling and protecting rare and endangered species, including Tibetan antelopes, and their habitats in Hoh Xil since 2007, together with his colleagues.

Their hard work has paid off. The population of Tibetan antelopes in Hoh Xil, a species under first-class national protection in China, has increased from less than 20,000 in the 1990s to over 70,000 by 2021.
