Identification and Reproduction

Identification:

  • Feral swine, also known as wild pig, appear very similar to domesticated pigs. 
  • Widely range in size, weight, and colour. 
  • They can weigh from 150-600 lbs, much larger than the wild pigs in their native range. 
  • Males have sharp white tusks. 
  • Coat is bristly and thick. Colour will range from grey, brown, black or white (rarely), and coating pattern may vary. 
  • Tails have short hairs extending at the tip. 

Reproduction:

  • Feral swine reproduce very quickly. 
  • Females can give birth to 6-10 piglets per litter and can reproduce several times in year. 
  • These animals reach sexual maturity very quickly; females as early as 5-8 months old. 

Habitat & Ecology

  • They are very adaptive and can live in a variety of habitat types. 
  • They are only restricted by snow as this impacts their access to water and ability to forage.
  • These pigs often travel in groups, often found in riparian areas with a water supply.
  • Their range continues to extend.  
  • Their lifespan ranges from 15 to 25 years. 
  • Male feral swine tend to be solitary outside of the breeding season. 
  • They are also known as fast runners and capable swimmers. 

Impacts

  • Feral swine are very distructive and destroy crops and property. 
  • Can prey on livestock such as goats and sheep. 
  • Can carry and spread diseases and parasites that can affect livestock and wildlife. 
  • They can dig tree roots and rub off bark, damaging ecosystems. 
  • They create wallows or mud pits that alter pond and wetland systems. 
  • They displace wildlife and harass livestock. 
  • They compete with wildlife for food. 
  • They predate on reptiles, bird eggs and small mammals. 
  • They have been known to create above ground shelters, termed "pigloos"

 

Management

  • Prevention is key for this invasive species. 
  • Do not leave out garbage or any potential food source outside. 
  • Ensure fence system is in place to protect livestock and consistently monitor livestock.
  • Do not release feral swine.  
  • It is legal for anyone with a hunting license to hunt feral swine. 
  • Report any feral swine sightings.
