What are the characteristics of the black biodiversity?
At the press conference of the 2021 China Yunnan Puer Black Flower Face Festival, Tang Yongping, director of the Management and Conservation Bureau of puzuhei Provincial Nature Reserve, gave a detailed introduction to this.
Puzuhei Karst National Wetland Park was approved by the State Forestry Administration for pilot construction in 2011, and in 2015, it was listed by the State Forestry Administration as one of the 22 key national wetland parks in the country, and is the only wetland park selected in Yunnan Province. In December 2017, it officially passed the acceptance of the National Wetland Park. Puzuhei Wetland is located in the tropical limestone mountainous area of Southeast Yunnan, and the wetland and the shishan peak forest are integrated, forming a unique natural landscape and a special karst lake wetland ecosystem, which is very representative of the karst landform of Yunnan, Qiangui and Guizhou in southwest China. It is precisely because of the unique geomorphological characteristics that the unique biodiversity characteristics of Puzhu Black have been bred.
First, the ecosystem is diverse. The Puzu Black Wetland Ecosystem includes three aspects: terrestrial ecosystems, aquatic ecosystems and cave ecosystems. Terrestrial ecosystems can be divided into forests, shrublands, swamps and other types, and aquatic ecosystems include river ecosystems and lake ecosystems.
Second, organisms are rich and diverse. The unique karst landform and hydrological environment of puzuhei wetland have bred rich biodiversity and uniqueness. There are 823 species of vascular plants: 46 species of ferns, 16 species of gymnosperms and 761 species of angiosperms. There are 6 species of amphibians, 10 species of reptiles and 16 species of mammals. There are 18 species of fish, 3 species endemic to the land, and 209 species of birds.
Third, species are unique. Among the species currently counted, three endemic fish species have been found, namely the loach of the blind plateau of the hill, the golden ray of the north of the hill and the eagle-beaked golden ray. In addition, among the existing species, there are also animals and plants under national key protection: 3 species of wild plants under national level II key protection, namely sea cauliflower, wild diamond and fan fern; 3 species of national level I key protected birds - golden eagle, oriental white stork and black-necked crane, 20 species of national level II key protected birds such as kestrels and sparrowhawks, and 131 species of birds belonging to the "List of Terrestrial Wild Animals Under National Protection that are beneficial or have important economic and scientific research value".
Up to now, Qiubei County has invested a total of 132 million yuan for the protection and restoration of Puzhehei Wetland, completed the construction of 8.1 kilometers of lakeshore protection belt and the restoration of vegetation in the lakeside belt, restored 1631 mu of mountain vegetation in the river basin, restored 1369 mu of vegetation at the source of water sources, and closed 2558 mu of mountain forest area. The construction of Puzuhei Wetland has effectively protected and restored the wetland ecosystem, protected the biodiversity of the wetland, and provided a good habitat for birds.
