In Swan Lake, many black swans inhabit the waters, move in pairs or groups, feed on aquatic animals and plants, and build nests in hidden places near the water. Each nest lays 4-8 eggs and lives for 20-25 years. Besides the black swan, we can also see dancing egrets here. Egrets fly with unusual momentum. "Mao Tao? Zhou Song wrote in a poem: "The heron is in the air, and it is in the west. "Egrets are born beautiful, slender, with white feathers, spotless, proud and elegant, like a noble Snow White. There is also a bigger bird in Swan Lake-the pelican. They have a pair of very special mouths, big and yellow. Especially the mandible, there is a big "skin bag". With it, pelicans can catch and store many small fish at a time. You will also find that there are several kinds of waterfowl and ducks hidden in the great lake.
According to the preliminary investigation by Institute of Botany, Chinese Academy of Sciences, there are more than 30 families of aquatic plants, 100 species and hundreds of terrestrial plants in the first phase of the park. There are many kinds of aquatic plants, such as Acorus calamus, Dictyophora dictyophora, Alisma orientalis, Potamogeton crispus, Lotus, snapdragon, reed, Crotalaria japonica, willow, water lily, Potamogeton crispus, etc. The natural succession of plant communities is gradually approaching the original state, which is natural and harmonious. The number of birds that naturally inhabit and migrate in the park has increased from less than 10 at the time of restoration to more than 40 species and more than 3,000 birds. Aquatic animals are rich after protection and artificial breeding. Fish, shrimp, crab, mollusk and plankton are all natural systems.
Cuihu Wetland Park will take wetland ecological protection as the premise, take wetland ecological landscape as the main feature, and strive to build a comprehensive popular science wetland center integrating wetland eco-tourism, cultural sightseeing, learning and research.
In order to strengthen the research and monitoring of the ecological restoration effect of Cuihu Wetland, get a deeper understanding of birds' living habits and find out the background of wetland bird resources, from July 20 10, Cuihu Wetland Park and School of Life Sciences of Capital Normal University launched a one-year research on "Bird Census Project of Cuihu Wetland Park". Wild birds 16 1 species have been monitored in the whole park, among which there are many national key protected birds and endangered species, such as migratory bustard and black stork. These two kinds of birds are not only rare in Beijing, but also only a few thousand in the world, which have declined rapidly in the past two years. This very rare population appears in Cuihu wetland, which shows that the ecological restoration effect here is obvious.
The most obvious ecological benefit of Cuihu wetland lies in providing bird habitat. Due to less interference and the gradual restoration of vegetation in recent years, more and more birds are attracted. Every spring and autumn, a large number of migratory birds use Cuihu as a "transit station" for migration, where they can get food and replenish their physical strength, and then migrate north or south. With the gradual improvement of the ecological environment of Cuihu Wetland, some migratory birds have become "resident birds", and the species of birds in the park are becoming more and more abundant.
