The northern part of the United States is ready to face the invasion of superpigs, which have moved in from Canada.
In 2021 alone, Canada killed 65% of its superpig population, but the wild boar population has not dropped significantly.
The staggering number of super pigs led the United States to control their access to the northern United States, but pig control is harder than flood control, and wild boars are more difficult to control than flooding.
There are precedents for flood control, but little is known about controlling wild boars, and even in California, there is a trend towards wild boar infestation.
What exactly are these super pigs coming from, and why are they threatening the northern part of the United States?
And why is it so difficult to control pigs?
Super pigs migrate to the northern part of the United States.
Super pigs are actually Canada wild boars, which are gradually migrating to the northern part of the United States in order to breed suitable offspring.
At the same time, because of the large number of wild boars in Canada, they migrate to the south in groups, increasing the threat in the north.
Although barriers have been erected in the northern part of the United States, Canada superpigs are still migrating south.
How are these super pigs different from native United States wild boars?
Canada super pigs were originally just wild boars in Canada, what allowed them to breed in such numbers.
The number of wild boars that should not be underestimated is also difficult for the United States to guard.
From the perspective of vision, wild boars are only divided into native and foreign, in fact, foreign boars are super pigs, and native wild boars are ordinary wild boars.
Canada super pigs have been introduced since about 1990, and since people entered the New World, they have brought a lot of new things, and they have brought familiar animals in order to survive better.
Coming to the feet of humans, these animals reproduce quickly, providing humans with a lot of meat resources, and because they are untamable by nature, they quickly breed in large numbers and become difficult animals to deal with in the eyes of people.
There are many species of these animals, and wild boars are one of them, so wild boars are not native animals, they are all introduced species.
The original purpose of introducing wild boars was simple: to breed them for human consumption.
But these wild boars cannot be domesticated by humans, and it is clear that there are no strict restrictions on the environment in which they live.
Once the wild boar is reproduced, its population increases exponentially because of their extremely strong reproductive cycle and reproductive capacity.
It is three times more fertile than a conventionally domesticated animal, and can reproduce once every three months, and can breed seven to eight pups at a time.
As a result, wild boars multiply very quickly, and eventually wild boars begin to spread all over the world.
Especially in the southern United States, where there were only a few hundred wild boars at first, they could not stop their own reproduction, and in just 40 years, they bred to 1 million.
Later, it grew at a rate of 40% per year, which is unpreventable, and today the wild boar population in the southern United States has reached 4 million.
And that's just the number in the southern part of the United States, which continues to increase as wild boars gradually expand north, and once the north is occupied by wild boars, the south will also be occupied by wild boars.
Canada Super Pig is stronger.
What is the difference between Canada Super Pig and United States Wild Boar?
The difference is that the number of super pigs in Canada is large, and their size is generally larger than that of wild boars in United States.
You know, wild boars are generally 1 to 2 times the size, but Canada super pigs can reach 3 to 4 times the size.
The larger the body, the more energy it can store, and the larger the body, the more it consumes and the more resistant it is to the cold.
The more energy it can store, the longer it can be maintained, so Canada Super Pig can survive longer.
But United States wild boars are different, and United States wild boars are generally only 1 to 2 times their size.
And the number of wild boars in the United States is relatively small, usually around tens of thousands, and under people's control, the number has not grown much.
And wild boars in the United States are very poor in cold resistance, relatively small, and the number of breeding numbers per year is relatively small, only 7 to 8 per year.
In comparison, Canada super pigs are 100 times more numerous than United States wild boars and twice as large as United States wild boars, so Canada super pigs are indeed super pigs.
And the winter in the United States is known to be cold, and wild boars in the United States can only survive from May to October.
Cold winters can affect the survival of wild boars in the United States, but Canada super pigs can tolerate cold weather of minus 15° or even lower.
Therefore, due to United States small size and poor cold resistance, wild boars can only breed in the warm season and cannot breed in the cold season.
Super pigs in Canada are different.
Not only can super pigs tolerate the cold, but they can also survive longer, in smaller numbers, and in larger size, they are more resistant to cold.
People can control wild boars in the United States, but the super pigs that cannot be prevented have been attacking, and the United States is now showing a trend of flooding, so the challenge of controlling wild boars in the United States is intensifying.
Even though wild boars in the United States have been marginalized, their numbers are still increasing, which is related to the reproductive capacity of wild boars in the United States, which can breed at least twice a year, with 8 to 10 cubs at a time.
Moreover, wild boars in the United States can enter the next breeding cycle in 3 to 6 months, so they reproduce very quickly, and their numbers are increasing year by year.
Wild boars in the United States are highly adaptable, and they can be found in a variety of environments, whether they are forests, grasslands, swamps or mountains.
Therefore, in the United States forests or on the roads, wild boars can always be seen.
United States wild boars are so adaptable, people originally wanted to stabilize the United States ecological environment by controlling the wild boar population.
So as to avoid the excessive number of wild boars and ecological imbalance.
But now it seems that United States' pig control measures have not worked.
Pig control problem.
Although states in the United States have regulations for the control of wild pigs, what exactly are these control methods?
Effective pig control methods are mainly hunting, but hunting is the most difficult link.
People are intellectually oriented animals, and wild boars are physical animals.
When a hunter goes to hunt, the wild boar will escape as soon as possible, and the wild boar is difficult to hunt in the forest environment, and the terrain is complex, which increases the difficulty of hunting.
In addition, hunters also need to face the attack of wild boars, which are not non-aggressive animals, and once hunted, they will attack the hunter, so the danger of hunting is also high.
Even if you hunt with firearms, you can't hit the target 100% of the time, and you need a certain amount of hunting skills.
This requires hunters to hunt according to the habits of wild boars, and setting traps is also a way to control pigs, but it is not 100% effective.
Lifting fence traps are considered to be one of the most effective means of pig control.
When a boar walks into a fence trap, the fence cages it and waits for the hunter to kill it.
At the same time as setting traps, people will also scatter food at the location of the trap to trap wild boars, but some areas have not allowed the use of bait to hunt wild boars, which has caused great resistance to hunting.
And the bait to trap wild boars also needs to be skillful, not only to attract pigs, but also not to attract the attention of other animals.
However, hunting also comes with certain legal risks, because hunting wild boars can easily injure other animals by mistake.
Therefore, before hunting, it is necessary to inform others of the information of the hunting area to prevent accidental injury to others.
But hunters can't wait in the hunting area day and night, so they can only visit regularly.
In addition, lifting fence traps require regular maintenance to prevent clogging.
Although hunting is risky, it is even more difficult to control pigs.
epilogue
The wild boar epidemic causes more than $2.5 billion in economic losses to the United States each year.
There is still an urgent need for innovation in ways to curb wild boar populations.
It is urgent to introduce more effective hunting methods according to the living habits of wild boars.
