Not Evaluated

Endangered
Critically Endangered
Extinct in the Wild
Extinct
Not Evaluated/Data Deficient
• Species not yet assessed
• Not enough information
Least Concern/Near Threatened
• Not threatened
• Likely/close to being threatened
Vulnerable
• Face high risk of extinction in the wild in the distant
future
• Fewer then 1000 mature individuals with a stable
population
• Fewer then 10000 individuals: declining, badly
fragmented, or one vulnerable group
• Known, believed , or expected to decline by 20% in 10
years or 3 generations
• Range less then 20000 sq. km with range or numbers
are declining, fragmented or fluctuating
• More then 10% likely to go extinct on the next 100 years
Endangered
• Face a very high risk of extinction in the near future
• Fewer then 250 individuals with stable population
• Fewer then 2500 individuals: declining, badly
fragmented, or one vulnerable group
• Known or expected to decline by 50% in 10 years or 3
generations
• Range less then 5000 sq. km with range or numbers
declining, fragmented or fluctuating
• More then 20% likely to be extinct in 20 years or 5
generations
Critically Endangered
• Face an extremely high risk of extinction in
the immediate future
• Fewer then 50 individuals with a stable
population
• Fewer then 250 individuals: declining,
fragmented, or one vulnerable group
• Larger populations that declined by 80% in
10 years or 3 generations
• Range under 100 sq. km
Extinct in the Wild
• Captivity
• Artificial population outside of natural
range
• Consistently fail to find a single individual
Extinct
• No doubt that all have died

Habitat Loss
•
•
•
•
Mainly done by humans
Need for pasture
Creation of industries and settlements
Tourism
Hunting
• We have been killing animals for
thousands of years
• Fishing/Whaling
• Luxury Products
• War
• Superstition
Exploitation of Live Animals
• Young primates
• Pet trade
• Aquarium trade
Pollution
•
•
•
•
•
•
Plastics

Atmospheric pollution
Acid rain
Pesticides
Heat, Noise, and Light
Climate Change
•
•
•
•
Polar ice caps melt
Flooding of low-laying land
Warmer winters
CFCs
Introductions
• Out compete
• Deliberate
• Human transportation
Disease
• New diseases
• Captivity born
Genetics
• Inbreeding
• Interbreeding
Natural Disasters
•
•
•
•
•
•
•
Floods
Avalanches
Hurricanes
Fires
Landsides
Earthquakes
Drought
Conservation
• IUCN
• CITES
IUCN
• International Union for the Conservation of
Nature also World Conservation Union
• Started in 1948 as the International Union for the
Preservation of Nature
• Changed name in 1956 to IUCN
• Founded by governments, government
agencies, and nongovernmental organizations
• Over 1000 permanent staff and 11000
volunteers

CITES
• Convention on International Trade in
Endangered Species of Wild Fauna and
Flora also known as the Washington
Convention
• Conventions = international laws
• Main focus on animal trade
• http://www.cites.org/
Conclusion
• Endangered animals play a very
important in the affects on biodiversity and
ecosystems
• The lives of the animals and plants mainly
depend on how us as humans live
