Islands become haven for migratory birds in Qingdao thanks to ecological restoration

Islands in the rivers flowing through Qingdao City of east China's Shandong Province have been transformed into a winter sanctuary for various bird species, thanks to dedicated ecological restoration efforts.

Located at the confluence of the Baisha River, the main waterway of Chengyang District in northern Qingdao, and Jiaozhou Bay, the 11 islands have become a crucial stopover for over 160 species of migratory birds each winter.

Collectively known as "Youth Heron Island," the islands lie along a key migratory route, offering clear waters, lush shores, and abundant food for migratory birds.

Seven years ago, however, the ecological conditions there were unsuitable for birds. In early 2018, the newly established Qingdao Chengyang District Wildlife Conservation Association, in collaboration with local authorities, began restoring the ecosystem, including planting trees on the islands.

"All the saplings had to be transported to the islands by boat, and the planting holes had to be dug by hand with a pickaxe - no machinery was allowed," said Xu Liqiang, secretary general of the association.

The restoration was not without setbacks. At the beginning, inexperienced staff planted fast-growing tree species that were unsuitable for the islands' salty, alkaline soil, resulting in the loss of 600 saplings.

Learning from these mistakes, the team consulted experts and replanted saline-alkali tolerant varieties. Aside from environmental challenges, local resistance, especially from the elderly who were prohibited from clearing land for farming on the islands, added complexity to the project.

"We engaged with local schools to raise awareness through education. We involved students who then influenced their grandparents, helping unite the community around the restoration effort," said Xu.

By 2020, the islands began to flourish - vegetation grew, the water quality improved, and, most importantly, the first migratory birds arrived.

"When we recorded over 30 grey herons wintering on the first restored island, many of us were so moved that we cried. The restoration of all 11 islands was the result of young people working together, which is why we named them 'Youth Heron Islands'," Xu explained.

Faded ancient Chinese paintings revived with AI-powered restoration

Researchers at Chinese universities, backed by AI large model-powered restoration technology, are capable of reviving faded ancient Chinese paintings to somewhat bring back to life the original brilliance of precious cultural relics.

At the Laboratory of Art and Archaeology Image at the Zhejiang University in east China's Zhejiang Province, an artwork restoration team is employing advanced AI models to digitally restore the colors of the thousand-year-old traditional painting "Palace Lady Waving a Fan", which has significantly faded over time.

"By incorporating all our previous know-how, methods, paper outcomes about art restoration into a single AI model, we have obtained a very useful AI-powered restoration assistant," said Tang Tan, a research fellow with the School of Art and Archaeology of Zhejiang University.

In the past, restoring ancient paintings would mainly depend on the experience of restorers, who analyze the colors and conduct multiple digital simulations. Now, with the help of large AI models, the pigment composition of the painting can be analyzed, and AI can also factor in the painting's creation period and the artist's style to select the most accurate color scheme.

After the AI completes the visual simulation, restorers can manually verify the effects in the lab in the simulative color restoration.

"This is our materials lab. To restore the original colors of ancient paintings, we seek out materials to replicate the pigments historically used in the creation of artworks. For example, we apply these pigments onto reproductions of silk or paper, mimicking the original techniques and materials," Tang said.

The restoration team has digitally restored over 100 ancient paintings so far using the AI large model.

Moreover, they are collecting data on various colors, compositions and other aspects from past artworks, and using the vast information to retrain their AI model.

"We aim to integrate comprehensive knowledge of the full history of Chinese painting, including detailed depiction and color information of each artwork. This will enable us to build a database that will, in turn, enhance the expertise of our general AI model," Tang noted.
