For humans, wild boars are a terrible invasive species, but for saltwater crocodiles, wild boars are a great miracle of life.
The pig suddenly overdrowded
Flooded wild boars tear up soil and habitat, and omnivorous people look for food, like you have just been released from the epidemic containment area. According to Agriculture Australia, they cause $2 billion in annual losses and can spread disease to domestic pigs.
Australian wild boars are even notorious for preying on livestock pups such as lambs and calves, and their numbers have grown steadily over the years, with 130,000-140,000 wild boars in the Northern Territory alone, which can cause $263,000 a year in livestock losses. Authorities fear they will soon kill some protected animals.
According to the example of Texas, as many as 2 million wild boars there began to kill various animals, but little evidence was left, because wild boars often ate whole animals and were pig gods!
Good friend of the saltwater crocodile (food)
In the early 1970s, the number of saltwater crocodiles fell to a level of near extinction, naturally because of poaching, no, at that time, it should not be considered poaching, it was the hunting of Chia Tai Guangming. Since the end of World War II, Australia's Northern Territory has exported 113,000 crocodile skins, but the hunting of saltwater crocodiles was banned in 1971.
Since then, the Northern Territory's saltwater crocodiles have begun to breed like an inflatable one, and their numbers have increased from around 3,000 in 1971 to more than 100,000 today.
Seeking to explain the proliferation of crocodile mouths, scientists looked for dietary changes over the past half-century by comparing crocodile bones collected 40 to 55 years ago with bones that exist today. According to their article published in Biology Letters, changes in carbon and nitrogen isotopes in modern saltwater crocodiles suggest that predators have shifted from marine foods to terrestrial foods consisting mainly of wild boars.
Good fellow, eat wild boar developed.
It's not all because of wild boars
There are 24 million wild boars in Australia, and it is reasonable to say that saltwater crocodiles everywhere can eat refreshingly, so why are saltwater crocodiles in the Northern Territory full of mouths? Numbers skyrocketing?
Because other states do not have the vast floodplains of the Northern Territory, this provides an ideal nesting habitat for female crocodiles. In floodplains, no other animal can support crocodiles with such high nutritional value and biomass.
Invasive species managers see wild boars as the number one public enemy, and perhaps they are secretly cheering for saltwater crocodiles. Next, the researchers intend to confirm the effects of saltwater crocodiles on wild boar populations.
I think the large number of saltwater crocodiles seems a little scary. By eating wild boar, the number of Australian saltwater crocodiles has increased more than 30 times in 50 years.
