  1. Mountain Lion or Cougar Predator Ecology and Management Three distinct features of the behavior and ecology of vertebrate predators 1. Concepts of territoriality and home range

  2. Functions of territory defense

  3. 2. Response to varying prey density Functional response- Numerical response-

  5. 3. Predator selectivity- certain predators are known to only eat particular prey items

  6. Black-footed Ferrets (Endangered) prey almost exclusively on prairie dogs and other burrowing mammals

  7. Predators and Livestock Depradation Coyote Case Study

  8. Allow me to introduce myself. My name is Wile E. Coyote, Genius Case Study

  9. Acme Case Study

  10. Approximate distribution of Coyote in 1995 Case Study

  11. General Aspects of Coyote Life History 1. Member of the Dog Family, Canidae, which includes wolves, dogs, hyenas, jackals, cape hunting dog and fox 2. Tend to be more solitary than most other canids, except fox: although they will gather together at kills 3. Generally, do not form permanent pair bonds

  12. 4. They eat almost anything with some type of food value, including three groups that are important to man- domestic livestock, upland game birds and waterfowl

  13. 5. They have an interesting relationship with foxes- excluding them from habitats where both would occur. This is known as competitive exclusion or interspecific territoriality Waterfowl losses due to predation are greatly reduced in areas where coyotes have excluded fox

  14. Control Methods Wolverine Lethal vs non-lethal control

  15. Lethal Methods of Predator Control 1. Direct shooting 2. Trapping- both live traps and lethal traps 3. Chemical methods- M-44 devices 1080 Broadcast application of poisons

  16. Non-lethal methods 1. Live trap and relocate 2. Use of predator proof fencing 3. Flock/herd maintenance 4. “Guardians”

  17. Great Pyrenees

  18. Great Pyrenees guarding flocks of sheep and goats

  19. Maremma Guardian Dog with pal

  20. Nice collar! Anatolian Shepherd Dog aka Coban Kopegi

  21. Donkeys serving as livestock guardians, note: mules can also be used in this capacity

  22. Llamas as guardians for sheep

  23. Llamas make great pets/companions/partners. Why not pick one up today?
