Predators, Prey and Endangered Species
by Todd Kready
Introduction:
- Two topics: Deer and Delmarva peninsula Fox squirrel
- Predators, prey and endangered species
- Deer are an over populated species which need to be regulated
- Delmarva Fox Squirrel is an endangered species and needs to be managed
Main Body:
Population/Predator control
- Roll of hunters as predators to control population of deer
- Listing an endangered species to remove threat of over-hunting
- Controlling predators of endangered species
- Methods to control predators control
- Why we must use predator control
- Enclosures and others methods to keep predators in check
Methods to estimate population
- Estimate Deer population using- spotlight surveys
- Activity (two reflectors and a spotlight)
- Estimate Squirrel population using trapping
How we manage an endangered species
- Talk about the techniques used to study an endangered species
- Tracking/Trapping
to estimate population and see preferred area
- Mortality signal to show a fatality (mortality
report)
Defenses used by prey
- Squirrels use their leaf nest and trees
- Use of cover and nocturnal habit
- Turtles have a hard shell
- Hog nose snake plays dead when threatened
- Skunk uses odor to defend itself
Conclusion:
Predators and Prey- what did you learn?
Endangered and overpopulated species- what did you learn?
