What are the most representative animals and plants in Hubei?
Plum blossom-the city flower of Wuhan, it is not afraid of frost and snow, and it is awe-inspiring when the flowers bloom and wither; Its lofty character of firmness, tenacity, purity and purity is regarded as a symbol of the great spirit of our Chinese nation. Plum exploration and appreciation has always been an elegant cultural leisure activity for Wuhan people to welcome the Spring Festival. After 50 years of construction, the East Lake Plum Garden has grown to an area of 500 mu, with more than 5,000 plants (pots) of plums and artistic bonsai plums, making it one of the four largest plum gardens in the south of the Yangtze River. China plum blossom research center is located, and China plum blossom variety resource garden has also been established. The East Lake Plum Blossom Festival with the theme of appreciating plum blossoms is held here every year. Baiji dolphin is a bird with nine heads, a rare aquatic mammal living in the Yangtze River valley of China, and one of the five kinds of freshwater dolphins existing in modern times. As early as Miocene and Pliocene, the ancestors of baiji were once a widely distributed and prosperous species. Although it has gone through a long historical process, its internal structure and morphology have not changed much. The species that flourished in Miocene and Pliocene have now become fossils. Therefore, we call baiji a "living fossil". It is an important link in the study of biological evolution history. Its vision has deteriorated, but its sonar system is particularly developed. Studying the biology of baiji is of great significance in bionics, military science and medicine. According to ancient documents in China, baiji lived in the Yangtze River more than 2,000 years ago. In addition, the distribution of baiji has been reported abroad since this century. At present, it is estimated that baiji dolphins are only distributed in the middle and lower reaches of the Yangtze River with a length of about 1 1,400 km from Jiangyin, Jiangsu to Jingsha, Hubei. White dolphins are rotating, with long and narrow jaws almost equal in length and slightly upturned snout. White dolphins have a blue-gray back and a gray-white abdomen. The white dolphin's food is mainly common freshwater fish, and the weight of the fish it eats is about 250 grams. White dolphins usually consist of a few to a dozen heads, usually 2-3 heads. White dolphins always lead the way when swimming. In the middle, there are either a large dolphin and a small dolphin caressing the young dolphin, or there are young dolphins that can live independently; Medium-sized individuals (young dolphins) or large individuals (mature dolphins) follow last, swimming from one water area to another. The waters that baiji likes to inhabit are all over the Yangtze River, close to Jiang Xinzhou, and located at the intersection of the mainstream and tributaries. Judging from the biological environment here, a large amount of fertile soil is deposited along the shoal, which gradually emerges from the water in dry season, and a large number of weeds and aquatic plants grow on it, which are submerged by the river in flood season, creating a good environment for fish-eating organisms. It is rich in organic matter, with a large number of plankton and epiphytes. In some places, there are many molluscs, aquatic insects and crustaceans, and fish are fattened here, which also attracts baiji to come here for fishing and activities. Baiji dolphin is one of the freshwater dolphins and the least number of all cetaceans. Before 1980, little was known about the population of baiji. During the period of 1984, it was preliminarily reported that the population of baiji was 400. 1986, the population of baiji in the Yangtze River was about 300. The investigation after 1986 showed that the population of baiji was still decreasing rapidly, about 200 in 1990, but it was less than 100 in 1995. Today, this species is in an extremely endangered state. It is the most endangered animal in China and one of the most endangered animals in the world. If no measures are taken, the baiji will cease to exist in a few years. According to our years of scientific investigation and study, the decrease in the number of baiji is not only because it is an ancient and declining species, but more importantly, it is closely related to the increasingly frequent economic activities of human beings in the Yangtze River. For example, the construction of the Yangtze River water conservancy project, the development of fishery, the development of shipping and the water pollution caused by the industrial construction along the Yangtze River have directly or indirectly brought adverse effects on the survival of the baiji, and these effects are still intensifying, leading to the extinction crisis of the baiji. Baiji dolphin may become the first dolphin in the world to be extinct due to human activities!
