Endangered Species Worksheet What are the criteria for determing whether a species is rare, threatened or endangered?
Do these criteria vary if the organism is plant or an animal?
On a separate page of paper, construct a table to compare the classification systems used by International organizations, such as the World Conservation Union (also known as the IUCN), countries (such as the United States) and states (select your home state under the Natural Heritage Resources).
Are the criteria different at the level of the state, federal government or international concerns? Why do you think these differences exist?
What laws are used to protect rare, threatened and endangered species?
