26 species of aquatic plants in Jiangsu

[] Jinling Evening News reported the extinction Domino once opened, investigation said the consequences be unbearable to contemplate, a species reduction, related destruction will affect 10 to 30 depending on the plants, insects and animal, and in all organisms, threatening aquatic plants facing more because of the degree of attention, it is far lower than that of terrestrial.
Recently, College of life sciences, Jiangsu Province Bureau of marine plant resources and environment Nanjing Normal University Joint Research Institute of Jiangsu north and south of the aquatic plant conducted a thorough investigation, the investigation lasted more than a year of the results is not optimistic: the living environment of aquatic plants in Jiangsu is suffering a serious threat to Chuncai trapaincisa these past common aquatic plants now hard to find, on the brink of extinction.
Emergency: Isoetes extinct
Isoetes sinensis endangered, Brasenia schreberi vulnerable trapaincisa in an emergency, people like Gordon actually became vulnerable species … …
Jiangsu aquatic plant survival situation is worrying, as the investigation of aquatic plants in Jiangsu responsible person, Nanjing Normal University School of life sciences, Professor Ding Xiaoyu on the Jiangsu aquatic plant survival situation is quite worried. He told reporters, according to the survey, in Jiangsu there are 26 species of aquatic organisms has been threatened in “ ” state, which belongs to the national endangered species, 1 species, 12 rare species, vulnerable species is 13, in addition, 2 varieties of lotus precious class farmed are very valuable and easy dangerous varieties.
Ding Xiaoyu said sadly, the current national endangered species of Isoetes sinensis in Jiangsu has been extinct, more than a year of investigation, in the province did not find any plant Isoetes figure, its genetic related gene resources have disappeared, only some college students system can prove the existence of precious specimens it was in Jiangsu on this piece of land.
Reason: rely on water to eat water
Jiangsu is one of the most famous rivers and lakes in China. In the past, the lake became a “ ” Ding Xiaoyu said, by water to eat the home of aquatic plants.
In addition to artificially eradicated farmed “ bias ” also make some worthless “ ” aquatic plants living space was occupied, such as the old people eat fish crab in Brasenia schreberi, is under the condition that the growth area of Brasenia schreberi shrinking gradually spread in the Zizania caduciflora community under the background of a lot of Brasenia Tong swamp wetland waters began to transition, the production environment is destroyed, the 90s can find wild species of it, has been basically does not exist.
In addition, for these local rare aquatic species, is the greatest threat of invasive species, such as peanut, water hyacinth, their great survival strength will occupy the estate space of aquatic plant, reduction in the distribution of these species area.
