Scientists Warn , Invasive Feral Pigs , Pose a Threat to the US.
'Quartz' reports that wild hogs 
from Canada are on the verge 
of invading the United States. .
According to recent research, invasive wild pigs 
have a "high potential" of crossing the Canadian 
border and establishing new populations.
With no natural predators in states like 
North Dakota or Montana, the animals 
are able to quickly increase in numbers. .
This rapid population growth can cause voracious 
consumption of native vegetation, small wildlife 
and farmed crops in the region.
Feral pigs are also known to carry a number 
of potentially dangerous germs capable of 
jumping to pets or even the occasional human.
'Quartz' reports that the feral pigs that have invaded 
parts of the southern U.S. are typically a combination 
of escaped domestic pigs and wild boars from Eurasia. .
In the 1980s and 90s, Canadian hunters 
deliberately introduced wild boars to be 
used as livestock and controlled game. .
Pigs that were released, or escaped, were able 
to mate with domestic pigs, producing what 
scientists often refer to as "super" pigs. .
These "super" swine are larger, hardier 
and more resistant to the cold. .
We went from having a general 
concern about pigs crossing the 
U.S./Canada border to having very 
detailed maps showing where they’re 
most likely to move and establish 
populations. This can be used 
to target control efforts, Ryan Brook, study author and professor 
at the University of Saskatchewan, to 'Quartz'
