On a global scale, the number of biological populations can be said to be very large, and with the change of ecosystems, more and more biological populations gradually disappear or become extinct, for the simple reason that most organisms are constantly hunted and killed, destroying habitats, etc., so it is impossible for organisms not to decrease. Of course, under the circumstances of reduction, the protection of wild animals has also emerged.
At least in China, the protection of wild animals has been done very well, and many scarce biological populations in China have been restored, such as: giant pandas, Siberian tigers, North China leopards and so on. So that's what makes us happier. Of course, this is also true abroad, and the protection of some scarce species is not bad.
Weight up to 1000 kg! The North American forest bison, declared extinct, is back
According to the report, the North American forest bison is a scarce species in the Alaska region of the United States, the species was declared extinct as early as 1941, but after the declaration of extinction, the species was accidentally discovered, so under the increased protection of humans, the biological population has also expanded, and the number has increased a lot. Let's take a look at what kind of bison this is.
The American forest bison is actually a branch of the American bison and is the largest mammal in North America. This cow appears to be a more "cute" species, but in essence, the North American forest bison ," which is "under the surface", is very strong. It is a more fierce animal. It weighs up to 1,000 kilograms, making it a relatively rare species in the biological world. The biggest weapon of this stealth aggression is the "double horn" on its head, which has a pair of upwardly curved sharp double horns on its head, and does not flinch even in the face of the most aggressive predators.
You can rush directly at each other. And its "double horns" also have obvious concealment, right in their brown hair. Therefore, if other creatures are not paying attention during the battle, it is enough to kill them. The creature, which inhabits the boreal forests of North America and is limited to North America, is a relatively narrow species with a slightly narrower distribution range, and overall, its body is thicker than that of the European bison. However, the body and limbs are not as long as those of the European bison, and their sense of smell is good and their vision is poor, which is its basic feature.
The creature was declared extinct in 1941, relatively 80 years later, but when it was found to still exist in the wild, not in 2021, this needs to be separated. After the extinction was declared, and also in the 1950s, biologists discovered a small population of North American forest bison in Canada, so the protection of the species was increased. Subsequently, conservation centers for wild forest bison in North America were established, and there were several more.
So with this kind of strength, the number of wild forest bison in North America has exceeded 2,000. In 2015, the Alaska Wildlife Conservation Center had a total of 160 North American forest bison, of which 130 were released to nature. Of course, this creature is still good to release, and their main food object is the kind of plant that "grass and sedge", so there is no possibility of affecting people at all. And american bison have few enemies that threaten them, except for humans.
Of course, then again, in addition to people, the natural enemies of the American bison are also more special, the main natural enemies are - gray wolves and poisonous rattlesnakes, wolves mainly attack more in the winter, may also be because of the lack of food in winter, so they chose to prey on the American bison. Indeed, although the strength of the American bison is very strong, it is still difficult to resist when facing the group attack. And there are also requirements for wolves here, you must have more than 7 wolves to do it, and fewer wolves cannot attack and win.
Snakes are different, poisonous rattlesnake attacks are not to be eaten, mainly unintentional touch, rattlesnakes will bite the ankles of cattle, this damage is sometimes fatal to calves, this is the general situation.
Therefore, it is also more gratifying to see the appearance of the North American forest bison again, indicating that the population of this species has recovered. Although not in our country, but, on a global scale, the disappearance of any kind of organism may trigger a chain effect of organisms, so from the perspective of biological protection, we must protect any biological population well, no matter where, we must have such awareness, while reducing the impact of alien species on indigenous species, this is the general situation.
