  • By feeding on plants and vegetation wild boars affect the abundance of plant species by rooting.
    Rooting causes a great disturbance to plant community. Wild boars root at an average of 5-15cm deep which affect the species that are both consumed directly by wild boars and also those that are not eaten, but whose roots are left exposed.
    Wild boar traveling patterns also lead to physical alterations of the ecosystem by increasing the soil erosion.
    Rooting is their natural feeding behavior
  • The wild boar presentation

    1. 1. By: Lauren Smathers Environmental Biology Lab- Section AQ
    2. 2.  These mammals are in the species of the pig and part of the biological family Suidea.  They are usually black in color and have straight tails. Wild boars can weigh up to 300 pounds.  The males have tusks that grow out of the sides of their mouths.
    3. 3. Wild Boars have tough snouts, which help them dig for food. They do not have very good hearing or sight, but make up for it with their sense of smell. Their ears always stand straight up, unlike farm pigs, whose flop down.
    4. 4. Above: Where boars wallow to stay cool. Left: A boar’s bed Boar’s tracks
    5. 5. We chose the Wild Boar randomly based on its name and the fact that we did not know any information about this animal.
    6. 6. Wild Boars are native across Northern and Central Europe, the Mediterranean Region, and much of Asia. They have also been introduced in the Americas and Australia for hunting purposes.
    7. 7. Wild Boars mate between the months of November and January. The females are then pregnant for 110-115 days. They can have between one and ten piglets.
    8. 8.  Boars like to live near ponds and streams in the forest. They prefer to live near oak trees, for their nuts.  Boars do not have sweat glands, so they roll in the mud to stay cool.  The rest of the year, boars eat roots, fruits, mushrooms, small birds, and rabbits.  If there is plenty of food, they will live in a 10 mile radius; if there is a scarce amount, they will travel up to 50 miles.
    10. 10. The wild boar , a native of Eurasia made its introduction to the continental U.S. In 1539 on a ship commanded by Fernando De Soto . The wild boar was released for hunting purposes for food by humans. Later they were released again in the 1900s for sporting purposes.
    11. 11.  Wild boars feeding on plants have a negative affect on the abundance of plant species by rooting (natural feeding behavior)  Wild boars cause soil/landscape erosion. Crop damage is caused because wild boar feeds on almost every type of cultivated plant  Wild boars affect the animal community negatively by disturbing the habitat community of various animal species. (i.e. ground nesting birds) and by competing with other species for food.  Wild boars costs an estimated $805 million dollars a year in America.
    12. 12. Of all of the members of the pig family, sus scrofa occupies the largest range. With origins in Europe, Asia, and North Africa there are numerous island populations that are included in its native range. Wild boars are continuously released in Texas to increase hunting opportunities and economic returns.
    13. 13.  While wild boar has earned the reputation of “ pest”, they are an integrated part of the diets of humans.  They can also feed on human garbage which make them efficient and valuable in some agricultural systems.  Wild boars are hunted for sport and smaller wild boar are prey for larger animals such as wolves and tigers  Wild boars does disperse seeds which can be a positive contribution
    14. 14.  Fences • Save crops • Keep boar off streets and highways • Keep boar out of public areas • Keep boar from endangering family pets
    15. 15.  Traps • Used to subdue wild boar either to move them to a different location or for a use of lethal control • Traps account for 14% of hogs that are hunted
    16. 16.  Snares • Account for 55% of the wild boar removed • Steel cable with a loop that catches the animal as it passes through it • Mostly placed near the opening of a hog den
    17. 17.  Hunting with Dogs • The use of dogs to follow wild boar scent • Once the dog follows the scent to a wild boar the chase is on • Wild Boar cannot outrun a dog • Hunter catches up and shoots the boar
    18. 18.  Aerial Hunting • Using a fixed wing aircraft or helicopter to shoot wild boar. • Accounts for nearly 17% of boar hunting • Requires an experienced pilot and a excellent marksman
    19. 19. New Fencing Design • Fencing is a very effective method of control, but the fence needs to made out of sturdier material that is cost effective at the same time because fencing is very expensive and boars usually break the fences.
    20. 20.  Integration • We need a combination of all methods. A combination of greater education for greater public awareness, poisoning, fencing, hunting, caging, etc. • Integration is really the only solution, using one method at a time is not working. • We need a method of control that combines all the current best methods.
    21. 21.  Hunting • Everyone wants to hunt deer, ducks, and turkey. Why not boars? • In some states they get rid of the hunting season altogether so people can hunt them all year round. All states should do this. So whenever it is not a hunting season for something that people like to hunt, they will hunt boars.
    22. 22.  Education • Raising awareness of the problem could be done through holding public forums on the problems of wild boars so everyone will know about the damage they do to the crops and food supply. • If more people are educated on the problem, this will reduce the risk of an unintentional introduction of wild boars.
    23. 23.  “Wild boars are an ecological black box.” They represent many unknowns to many biologists.  We need more research and better understanding of the impact that they have on our environment.  Wild boars can even harbor and transmit diseases to humans and to livestock.  With more understanding, research, and education we can solve the problem of the wild boar.
