Ministry of Environmental Protection officials said there are 488 invasive species in China

Kunming, Yunnan, one by water hyacinth blockage of the river, water hyacinth has become a local “green contaminant.”

some alien species, we do not know, do not understand. It is not broke, we do not know that it is not to become invasive species.

an incubation period of invasive alien species, hidden to a certain extent, there will be a pandemic outbreak, this time we discovered that this thing is very scary.

Morning Post correspondent Long Yi

now how dangerous domestic invasive species? For this problem, the State Environmental Protection Department of Nature and Ecology Conservation Biology, Wang Jie, Director of the safety management of the answer is no choice – in serious condition, recovery is not optimistic.

“a recent survey, there are 488 kinds of invasive alien species.” Wang Jie said the figure is clearly conservative, because “there is an incubation period of invasive alien species, hidden to a certain extent, there will be a large outbreak pandemic, this time we discovered this thing very terrible. ”

no timetable to build early warning system

Oriental Morning Post: The current situation at home and abroad to how to invasive species?

Wang Jie: of alien invasive species as a whole the situation is very serious, especially in the southwest and coastal areas. Spartina then introduced, in order to protect the embankment, but has now been introduced to other regions, including Guangxi Beihai, Spartina flooded, affecting the production of local life, including the impact on the environment very seriously.

water hyacinth as a feed is introduced, and now the people’s standard of living, do not feed it, but it has now grown everywhere, growing very rapidly in the southern region has become a “green pollution.” There are also water, peanuts, is a large-scale outbreak has affected the local fishing industry, blocking water transport.

Oriental Morning Post: The main hazards of invasive species where?

Wang Jie: against invasive species is the main natural ecosystems, because after the invasion, will destroy the biological diversity of other native, the other species living space squeeze, elimination of other species. This makes the ecology in an unstable state, lost his balance, this is the greatest risk!

The second hazard is mainly on agricultural production. As Eupatorium soaring everywhere, especially in the fields, their houses, especially in the Southwest, where it can be long, afraid of floods and droughts. Let’s Southwest drought, when it is still live gusto. And its seeds carried by the wind, spreading everywhere, very easy to spread. Therefore, the harm of its people is relatively large.

addition to the farming industry, the impact of traffic is also great.

the final analysis, the most powerful, is the destruction of natural ecosystems. And once damaged, difficult to restore, or even can not be restored. After the destruction of natural eco-system, the real can not be restored. After the invasion in some areas, there is no way, can only turn a blind eye.

example, Eupatorium can grow on the cliffs, where people climb. You should get rid of it off, people are difficult to do.

Oriental Morning Post: The current number of invasive species specific number?

Wang Jie: It is not particularly accurate and uniform data, a recent survey there are 488 kinds of invasive alien species, including 265 kinds of plants, animals, 171 kinds, 26 kinds of fungi microorganisms. Because there is no nationwide survey carried out large-scale alien species, only the most parts of the investigation. Second, some alien species, we do not know, do not understand. It is not broke, we do not know that it is not to become invasive species.

an incubation period of invasive alien species, hidden to a certain extent, there will be a pandemic outbreak, this time we discovered that this thing is very scary.

Oriental Morning Post: The incubation period there will be more long?

Wang Jie: different types, it is not the same as the incubation period. For example, like the plant in the country has been hidden for 20 years before the outbreak, after the outbreak of a very powerful, overwhelming, where is. Especially in the Guangdong area, the whole protected area very serious environmental damage. This rattan strangling of trees is very powerful.

Oriental Morning Post: What are invasive approach?

Wang Jie: mainly in three ways: one is the introduction of man-made, intentional introduction; one is no intention to introduce, common in tourists who adhesions, and spread to another area off the species; there is the natural spread, like the wind blowing the seeds float. This is mainly in three ways.

Oriental Morning Post: At present, whether the establishment of a national early warning system?

Wang Jie: This type of early warning mechanisms to carry out construction work is certainly in need of legal means, through legal channels. Schedule is not yet complete.

invasive species can be put into resources

Oriental Morning Post: prevention and control of alien invasive species problems, whether there is good control case?

Wang Jie: We know that the crayfish, is invasive alien species, and now we all like to eat, and catch are caught vain, mainly because it has value in use. There is also a special case of apple snails, apple snails have eaten the original value, but we will have to eat and found other disease, so do not eat, snails and everywhere began to grow. So take advantage lies in its own economic value, the key to be able to make good use of. So if the economic use of this breakthrough, if we can use, for people to value, control is more convenient.

Oriental Morning Post: The current economic value of such a breakthrough is more difficult to find?

Wang Jie: break point is this. Yunnan Institute for Ecological Agriculture as on the use of water hyacinth, after biological induction into another water hyacinth, water hyacinth purple root. This plant, in the waters of cyanobacteria growth, root secretion of allelochemicals can be broken down blue-green algae, cyanobacteria break down then it grew up, and finally made into organic fertilizer, such as this case is very typical, very good.

Oriental Morning Post: water hyacinth, the water hyacinth in Dianchi Lake is also currently to control pollution, a large scale, from a prevention point of view is reasonable?

Wang Jie: I think the purple is expected to become the root of water hyacinth may be a way. Dianchi Lake is very difficult to control, six years before the water cycle of time, virtually intact. After the flow of water pollution is not, and then want to turn it into water, it is very difficult.

should be like this, this thing must have resource. If resource not much of a problem. In the process of governance, must always pay attention to this aspect. The water hyacinth control in a certain area, remove and put it immediately into organic fertilizer.

Oriental Morning Post: resource implications?

Wang Jie: is to take these species into resources, such as crayfish can be made into food, they become food resources. Water hyacinth can be made into fertilizer resources, or to the formation of value.

Oriental Morning Post: The frequency of invasive species in recent years is kind of how?

Wang Jie: In recent years the frequency of invasion is increasing! Why? As economic integration, and very convenient transportation from one area to another area of ??species migrate faster than ever. Invasive species depends mainly on human migration, the spread of mankind to be much larger than the natural spread. There is also the unconscious conscious.

2008 before the opening of the Beijing Olympic Games, the most headaches is the fall webworm. This insect if you do not destroy it, will affect the athletes to play, because it has drive-light, fall webworm was also flooded, this species is unintentionally introduced, through the packaging material to the egg into the country.

Oriental Morning Post: When China began to pay attention from the problem of biological invasions?

Wang Jie: From the History view, liberation, reform and opening up, invasive alien species is not particularly obvious, is not particularly harmful. Because at that time, we are quite close, less foreign exchange, dominated almost all local species, but there are alien species. For example when the Rooster chrysanthemum, this species more in Henan Xinyang, which was then brought in the French missionaries, over hill and dale is 40 years, but only limited to this part. Reform and opening up, invasive species is relatively small.

reform and opening up, particularly on more. Because we open up large, including the nature reserve of strength, after breaking the natural development of the ecology of invasive alien species is very easy to drive straight. Economic and trade exchanges, globalization, transportation convenience, these are conditions caused by invasive alien species.

some mutual introduction of alien invasive problems brought about precisely is different between the invasion of ecological systems, and borders are not related.

tourists do not bring alien species immigration

Oriental Morning Post: At present the impact of harmful invasive species have relatively large what?

Wang Jie: There are 35 kinds of major damage, mainly national in 2003 released the first list of invasive alien species and the 2010 release of the second batch list of invasive alien species are the most affected .

Oriental Morning Post: What kind of science should be to treat invasive species, how do the people?

Wang Jie: because the current promotion of invasive alien species is not enough, everyone’s concept of alien invasive species is not very understanding, life without awareness. Including a lot of people do not realize that home invasion is also the risk of cockroach species. Some long-distance introduction of some of the plantation of ornamental plants, in fact, may have been unscientific, outdated.

Second, many of us do not realize the government level may be the future of biological invasions killer, and the result may not be eliminated, the invasion.

now beginning to realize that these problems in some places, the last drought in the southwest, most of the grass withered, and only Eupatorium still alive, farmers raise sheep do not eat, eat purple stems only Zeeland. Eupatorium toxic, water after eating, the results of one day die 30000.

Finally, I hope tourists do not intend to bring alien species, usually found in people in a timely manner, timely reporting.
