Speaking of alien species, many people may only cause a "sensation" if they are some creatures. For example: In 2022, there were rare white fox events. Although this creature looks mild, people still breed it.
However, after all, it is still an alien species, not a native species. Therefore, when we see this creature in the wild, we still hope to capture it and hand it over to the relevant departments for processing.
It is definitely not a good thing to see it in the wild. Although artificially bred white foxes are not strong in survival, once they survive, they may have more impacts. For example, if it reproduces with our country's native species, the white fox may also carry a lot of bacteria. If it bites people, wouldn't it also pose a great threat?
So, if you see it in the future, you will report it directly. However, besides animals, what we call "plants" are extremely threatening. The news that " poison flower " has once again sparked heated discussions among everyone. What's going on?
"Poisonous flowers" have appeared in many places across the country
Indeed, since 2022, many regions in my country have reported news about "Poisonous flowers". Therefore, it has become a fact that "poisonous flowers" appear in many places across the country in 2022.
Of course, the "poisonous flower" mentioned here is actually what we call Canadian Yizhihua. Everyone should know through this name. This is definitely not a local plant, otherwise it would not be called "Canadian Yizhihua".
And its appearance was also an accident. It was not available in my country itself, but in the 1930s, this plant looked very beautiful because of it. Therefore, it was introduced by my country and used as an ornamental plant .
However, after its introduction, the plant quickly survived and spread in the wild. Judging from the distribution of this plant in my country, it has been discovered in more than 11 provinces and cities.
It contains:
"Zhejiang Province, Jiangxi Province, Anhui Province, Hubei Province, Henan Province, Sichuan Province, Hunan Province, Shaanxi Province, Shandong Province, Guizhou Province, Jiangsu Province and Shanghai City".
Therefore, it is indeed not a good thing that "poisonous flowers" appear in many places across the country. It is mainly a Canadian flower, which is really a "poisonous flower".
Although it is a plant, the influence of plants is very strong. It is completely different from the conventional plants we see. Otherwise, it would not be called " plant killer ", "beast grass", " poisonous grass ", and the so-called "all flowers are killed where the yellow flowers bloom". How poisonous is
"poisonous flowers"?
"Poisonous Flower" - A Canadian flower has a very strong growth ability and can grow in river beaches, wastelands, roads, farmlands, and other areas. This plant only needs a little space to grow, and it can grow to more than 2 meters.
And the "most poisonous" part is its destructive power. The root system of the plant develops very well. As long as it grows around it, even weeds cannot be seen. It can be said that "no grass grows."
Because it has extremely strong ability to compete for sunshine, fertilizer, etc., it can absorb most of the ingredients in the soil. Therefore, other plants cannot survive at all, posing a threat to the ecosystem.
is like Shanghai, from Shanghai Chenshan Botanical Garden engineer Yan Jing once introduced that in Shanghai, there has been a strong destruction of Canadian yellow flower on surrounding plants. It occupies the ecological niche of local species through its strong competitiveness, causing local species to lose their living space.
simultaneously releases allelopathic substances to inhibit the growth of other plants, form large-area single-optimal communities, and reduce species diversity. So, its impact has been clearly seen.
Of course, it is not easy for this plant to be completely eradicated because its reproductive power is also extremely strong. Each independent plant can produce more than 20,000 seeds a year, and the seeds can spread by the wind.
At the same time, some biological populations such as birds can also be carried and spread. Therefore, it is possible to cover more remote areas. At the same time, there is another point, that is, after discovering it, if we accidentally leave a part of the root system when we clear it, then we can still see it grow in the next year, which is so strong.
So, this is "toxic" most plants in the plant world. From the known situation, we only have three ways to deal with Canadian flower, namely: manual removal, manual incineration, and chemical prevention.
If you want to talk about the method, chemistry may be the best. Of course, it would be nice if manual cleaning can be done thoroughly. Anyway, in the final analysis, that is, after seeing this plant, everyone should report it as soon as possible. Then we have "cut the roots" and we have discovered it in more than 11 provinces and cities. We can imagine that there are still many distributions in our country.
Summary
Whether it is an exotic plant or an exotic animal, it is not easy for our ecosystem. Over the years, our country has also made great efforts and finally seen changes in the ecosystem. Many scarce biological populations have expanded. If they are invaded by these foreign animals and plants, the impact on our ecosystem will inevitably be huge.
may even lead to the complete loss of the original ecosystem in some areas. According to the data from the "2020 China Ecological Environment Status Bulletin", more than 660 invasive alien species have been discovered in my country.
You can think about how many alien species are there. Of course, in addition to the trade we mentioned and the unintentional introduction of foreign species, with the rise of the pet wave, we have also seen a lot of people constantly buying and selling foreign species through their own means.
In 2021, my country's customs organized a special campaign of "National Gate Green Shield", intercepting 8,473 batches of living animals and plants such as foreign species in the delivery and passenger carriage channels, and increased by 98.43% year-on-year.
intercepted 590,800 pests and 65,100 quarantine pests throughout the year. For the first time, four dangerous pests such as lethal nematodes, lily of the valley short body nematodes, and North American toothed beetles were detected. There are many alien species "illegally introduced" by many people. So, this trend is definitely not a good thing.
Moreover, many people brought foreign species into my country and breeded them for a period of time, but they didn't like them, so they released them into the wild at will, don't.
has triggered a threat to the ecosystem. In 2022, " crocodile gar " appeared in many places in my country, and there are many alien species deliberately released by people.
Therefore, this still needs to strengthen everyone's awareness of protecting the environment. It is not easy for us to protect the earth's ecosystem, nor is it easy for us to protect our own ecological environment.
Maybe I think it will have no big impact on putting a creature and throwing away some plants. However, its subsequent problem cannot be solved by the word "throwing".
At the same time, I also need to remind you here that many people who raise pets, if they buy foreign species without reasonable formal procedures and are found, they may face prison. There are clear regulations on the breeding of foreign species. You can check it out and don’t “burn the body.”
