May 22 is the International Day for Biodiversity, the Department of Ecology and Environment of Jiangsu Province held a press conference on May 19, the meeting revealed that Jiangsu Province has monitored a total of 137 species of butterflies, an increase over previous years; amphibian indicator species - tiger striped frog, in xuyi county for the first time found 11 in xuyi county; aquatic life indicator species - four gill perch, in 2019 was rediscovered in Guanyun County...
There have been welcome changes in aquatic life in the province
Since 2017, Jiangsu has taken the lead in launching a background survey of biodiversity in the country, completed the survey work of 39 pilot counties in the province, and recorded a total of 4588 species in the province, and the composition of species species is relatively complex, of which a total of 1425 species of terrestrial vascular plants, 382 species of terrestrial vertebrates, 1401 species of terrestrial insects, and a total of 1380 species of freshwater aquatic organisms.
Wang Beixin, a professor at Nanjing Agricultural University who participated in the survey, said that the number of types surveyed in the pilot usually accounts for about 70-85% of the actual number of species, and it can be predicted that the number of biological species in Jiangsu is at least 5500, and may even reach more than 6500 species.
The number of red-crowned cranes and Chinese tiger butterflies increased
According to reports, a total of 165 rare and endangered species have been recorded in the Background Survey of Jiangsu. Among them, there are 52 species of terrestrial vascular plants, 4 species of terrestrial insects, 8 species of mammals, 82 species of birds, 5 species of amphibians, 7 species of reptiles, 6 species of fish, and 1 species of phytoplankton. Wang Beixin pointed out that the population and distribution area of rare and endangered species in Jiangsu have increased to varying degrees, and Jiangsu is gradually becoming one of the happy lands of these rare and endangered species. For example, compared with the historical survey from 2000 to 2010, the distribution of the national first-class protected species of red-crowned crane and oriental white stork, the national second-level protected species of Chinese tiger butterfly and the iucn critically endangered species spoon-billed sandpiper have been further expanded in Jiangsu.
Four-gill perch re-emerged in Guanyun County
Yang Guodong, a doctor of the Provincial Academy of Environmental Sciences, said in an interview that from 2017 to 2019, a total of 137 species of butterflies were monitored in Jiangsu Province, an increase over previous years. In addition, aquatic biological indicator species are four-gill perch, and the rediscovery of four-gill perch marks an improvement in water quality in the coastal waters of Guanyun County. For the first time, 11 wild tiger frogs under national secondary key protection have been found in Xuyi County, which proves that the ecological environment of Xuyi County has continued to improve in recent years. "The 'auspicious three treasures' (peach blossom jellyfish, egrets, and lichens) that were found in Wujin District of Changzhou in 2019 to migrate in pairs have become vivid samples of ecological environment improvement and biodiversity conservation." Du Qisong, deputy director of the Publicity and Education Department of the Provincial Department of Ecology and Environment, said. Yangzi Evening News/Purple Cow News reporter Xu Yuhua
