Endangered Species of
the
United States
Ecology
2010
Why is this Important?
• Humans are the Main Cause of
animal and plant Extinction
• Harming an Endangered or
Threatened Animal or plants Habitat
is Illegal
• Animal and Plant Conservation is a
Major part of Agriculture
Endangered vs. Threatened
• Endangered: A species that is in danger
throughout all or a significant portion of its
Habitat.
• Threatened: Species that is likely to become
endangered in the Foreseeable Future
Other Terms
• Extinct Species: A species that is no longer
living. ex. Dodo Bird
• Poaching: The Illegal Hunting, Killing, or
Capturing of Animals.
• Native Species: Species that have inhabited
a certain geographical Area for a lengthy
Period of time.
• Exotic Species: Introduced to a new
Environment by way of Human Activity.
FACTS
• Illinois has 37 threatened or endangered
species of plants and animals
• The Hawaiian Islands have 344
threatened or endangered plants and
animals
• The United States has over 1,000
Endangered and Threatened Species
Endangered Species Act
• Established in 1973
• Amended in 1978, 1982, and 1988
• Established Laws and Provisions for
Endangered Species in the United
States and other Countries
Making the List
• Population reduction of 50% in the last 10 years
• Area occupied is less than 500 Square Km
(311 sq Miles) - New York City: 303 Sq Miles
• Population is estimated at less than 2,500 Mature
Individuals and Number is Declining
• Total Population is less than 250 Mature Individuals
• Probability of extinction in the wild is at least 20%
within 20 years
Causes of Endangerment
• Habitat Destruction
• Overexploitation
• Introduction of Exotic Species
Habitat Destruction
• This is the Primary Cause of Species
Endangerment
• Humans are the main cause of rapid habitat
loss
• Fire Destruction and Timber Harvesting
• Urbanization
Overexploitation
• Species that become endangered due to the
rate at which the species is being Used
• Animal Trading and Illegal Hunting or
Poaching
Intro. of Exotic Species
• Exotic Species can disrupt the ecological
Balances of a Region
• Competition for food and Native Animals
Become Prey
• Scenario:
– What is the Apex Predator in the Area?
– What Happens if we introduce a new Predator?
– What Happens if we introduce a New Food Source?
The project has 3 components:
•Research: A bibliography with at least two resources
Approved websites include any that end in .edu, .net, .gov, .org
Do not use .com sites or Wikipedia!
You may use www.endangeredspecies.com,
www.nationalgeographic.com
*
*PowerPoint including the following information:
•Picture(s) of animal – atleast 3
•The common name and scientific name of the species.
•A description of the natural habitat and where in the world the animal is
found. Include a map for reference.
•Life history characteristics: diet, size of animal, housing requirements,
climate requirements, relationship with other species (Predator/prey),
how old are they before they reproduce, how many offspring and how
often do they reproduce
•Group or pack animal? All basic biology and interesting facts.
•Why this animal is endangered? For example: Over hunting? Habitat
destruction? When was it listed as endangered?
•What is the present-day world-wide population size? How many left?
•What conservation efforts are underway? What is being done to save
the species? Are the efforts working? What organizations exist to
promote the preservation of this species?
•Five question quiz (answers not included on the screen)
*A presentation to the class on your findings lasting at least 2 minutes,
but not longer than 4 minutes.
Last component:
Presentation to class
*A presentation to the class on your
findings lasting at least 2 minutes, but
not longer than 4 minutes.
Details Cont.
• What you need in your Project:

Group Details
• Each member is to be assigned either the Reptile,
Mammal, or Bird to research
• Each group presents their Project to the class
