Yancheng National Nature Reserve, located in Yancheng City, Jiangsu Province, is the largest coastal wetland nature reserve in China. It is well-known around the world as the most important winter home for red-crowned cranes.
Every autumn, when the weather turns cold, thousands of red-crowned cranes fly thousands of kilometres from Northern China and Siberia to Yancheng Reserve. They spend the whole winter here, because the reserve has a warm and mild climate, plenty of clean water and rich foods like shallow water fish, shrimps and aquatic plants. The wide and quiet wetland provides them with a safe and comfortable living environment.
The red-crowned crane is a large and beautiful bird. It has white feathers, a red crown on its head and long thin legs. It is one of the most precious rare birds in China, and it is listed as a national first-class protected animal. There are not many red-crowned cranes living in the world now, so Yancheng Reserve plays a key role in protecting them from dying out.
To protect red-crowned cranes and their wetland home, the government has taken many useful measures. Workers in the reserve feed the cranes every day, patrol the wetland to stop harmful human activities, and help injured cranes get better. Many volunteers also come here to take part in protection work.
Now, more and more people realize the importance of protecting red-crowned cranes and wetlands. Yancheng Reserve is not only a paradise for red-crowned cranes, but also an important place for people to learn about wetland protection and rare animal protection.
