Let’s consider conservation status of animals.
Write down the aspects that you think contribute to it.

Species populations are loosely grouped into six major categories.
The four categories of endangered species are:

 

Population

Geographic Range

Population Size

Population Restrictions

Extinction Probability

 

 

Extent of Occurence

Area of Occupancy

 

 

 

Least Concern

A species that has a widespread an abundant population

Near Threatened

A species that is likely to qualify for a threatened category in the near future

Vulnerable Species

30-50% population decline

< 20,000 km2

< 2,000 km2

< 10,000 mature individuals

< 1,000 mature individuals or an area of occupancy of < 20 km2

at least 10% within 100 years

Endangered Species

50-70% population decline

< 5,000 km2

< 500 km2

< 2,500 mature individuals

< 250 mature individuals

at least 20% within 20 years or 5 generations

Critically Endangered


≥80-90% population decline

< 100 km2

< 10 km2

< 250 mature individuals

< 10 mature individuals

at least 50% within 10 years or 3 generations

Extinct in the Wild

Only survives in cultivation (plants), in captivity (animals), or as a population well outside its established range.

Extinct

No remaining individuals of the species.

 

Look at the animals in this exercise.
What do you think their conservation status is?
