Genus spp.: Sus scrofa Family: Suidae

Non-native, invasive, exotic animal

NOT WILDLIFE, Classed as “Vermin”

Feral Pigs or Swine

  • Piglets: banded, spotted, belted & black (most common)
  • - Adults: black, brown, red,
  • spotted but generally
  • not “grizzled” looking
  • - Tails frequently curled.
slide4

“Wild Boar & Eurasian Hybrids”

  • - Striped piglets
  • Grizzle-haired adults
  • tails straight, not curled
  • In Indiana (Photo 4/07 Law. Co.).
slide5

All pelage colors possible but generally

the younger animals brownish,

eventually becoming darker

or blackish & grizzled as they get older.

Lawrence Co. 4/2007

Agricultural Concerns

  • Row Crop depredation:
  • Corn: pre-emergent, seedling, mature corn in fall
  • Soybeans: can’t digest, trails and trampling.
  • Wheat: spring grubbing/rooting
  • - Pastures and hayfields; grubbing & rooting activity
  • Damage to silage bunkers, round bales
  • Rooting/grubbing on pond dams & WRP levees
  • - Depredation on newborn calves, lambs, goats
  • Damage to trees, especially young trees (e.g., CRP plantings).
  • Damage to fencing.
  • Potential disease source for livestock and humans.
slide11

Feral Swine : Management and Disease Surveillance

Domestic and foreign animal diseases (FADs) of feral swine

  • Pseudorabies
  • Swine brucellosis
  • Bovine tuberculosis
  • Influenza
  • Tularemia
  • West Nile virus
slide12

Feral Swine : Management and Disease Surveillance

Domestic and foreign animal diseases (FADs) of feral swine

  • E. coli
  • Salmonella
  • Trichinosis
  • Streptococcus
  • Ticks, fleas, lice
  • Internal parasites
  • Toxoplasmosis and Trichinosis
slide13

Feral Swine : Management and Disease Surveillance

Domestic and foreign animal diseases (FADs) of feral swine

  • Classical swine fever
  • African swine fever
  • PRRS
  • Anthrax
  • Foot and mouth disease
  • Porcine circovirus
slide14

Human health issues related to handling infected hogs.

Some herds in Florida have a 50% Brucellosis infection rate.

slide15

Feral Swine : Management and Disease Surveillance

Feral swine disease surveillance

  • Locally based surveillance with national goals.
  • Classical Swine Fever is the focus
  • Development of DNA Profiles of source populations.
slide16

Native Wildlife Impacts

  • Ground nesting birds and mammals (nests, dens, young)
  • (e.g., quail, turkey, grouse, songbirds, & rabbits)
  • Herptofauna & invertebrates
  • e.g., Copper-belly water snakes, box turtles, Crawfish frog, smooth green snake, Eastern spade-foot toad, etc.
  • Competition for foods (e.g., mast, grubs, invertebrates)
  • Habitat degradation, vegetation disturbance (e.g., wetlands, prairie fields, forest understory.
  • Will eat mushrooms and tubers/rhizomes of wild flowers.
slide17

Water Quality Issues

  • Increased erosion, nutrient load, turbidity, bacterial & pathogen load in water sources (e.g., Salmonella, E. coli in CA irrigation sources led to national spinach recall).
  • Currently have wild hogs in the immediate watershed of John Hay Lake, water supply for Salem, IN.

Cultural & Heritage Issues

  • Destruction to small rural cemeteries, Indian burial grounds, landscaping, septic fields, nature preserves, & historical sites.
  • - Destruction to ball fields, golf courses (especially greens), grass airfields, vehicle accidents, & landfills.
slide18

Wallows in summer often associated with creek beds,

sloughs, low, cooler areas; fecal matter and increased turbidity in streams

Tusk marking on cedar

Bark stripping on cedar

slide20

Spring and Summer

Pasture and Hay field

Grubbing

slide21

Extensive hay and pasture field damage, disrupted soil wads prevent mechanical haying; losses high on alfalfa and clover fields.

Interior corn field damage often not notice until harvest, just a few pigs can wallow down 1-2 acre areas in a short time. Especially high damage loss on popcorn & sweet corn.

slide22

“Poor Man’s Grizzly Bear”

Growing Economic & Recreation vested interests

Increasing hunter desires for more feral hogs

Current land sale promotion in Lawrence/Jackson Couties.

slide23

In Indiana

Known captive sources of wild boar, Lawrence and Jackson Co.

Photo taken 2.24.09; ≥ 4 hogs visible from roadway

“shooter” hogs for sale to release on your own land;
