Caohai scenic spot
The resource of birds is very abundant here. The number of various migratorybirds living here amounts to more than 140 sorts, such as red-crowned crane、white-abdomnen golden pheasant etc. It’s one of the national bird reserves. The climate of Caohai is pleasant. Flowers and trees seem to grow in the cloud and sky. Gledes fly and fish spring. Wild gooses fly across the sky. At every end of autumn and beginning of spring， many birds swarm here .The Caohai nature reserve rests the sole plateau crane in the world-- black-necked crane. It’s the best place for watching birds in winter and preventing sunstroke in summer.Because of the intense movement of the earth’s crust about 150 thousand years ago, the broken pieces around Caohai rose constantly, but the lake basin fell down relatively, and formed a broken sunken basin. Later, because the karst was jammed and formed stagnant water, it became a plateau lake –that is Caohai we see today. The resources of animals, plants and aquatic products are extremely abundant, so it is classified as the state-level nature reserve and is regarded as the lake which possesses the most kinds of aquatic plants , inhabits the most black-necked cranes in winter and is the best area for watching birds in the world. It’s also called the Species Gene Storehouse and the Open Air Nature Museum in the scientific world. In March and April, although the spring has not come, wild flowers on the whole land in Caohai bloom at the bottom of the water or under the water. That scene isn’t as vast as that of the grassland in spring, but these abundant aquatic plants make Caohai take on a very graceful scene. It becomes veritable underwater grassland.
