Endangered Species Organisms on the Brink of Extinction
Endangered Species Objectives:
-
List and describe the factors that typically put species in danger of extinction.
-
Provide examples of strategies used to attempt to save species from extinction.
The Florida Panther (Puma concolor couguar) is a distinct population of North American cougars that numbers less than 250 individuals. Inbreeding and loss of genetic diversity in remaining panthers is believed to be depressing fitness (survival and reproduction). A variety of factors has led to the panther’s decline, including habitat loss and car collisions.
This video introduces the factors that typically put species in danger of extinction.
Species may be going extinct before they are ever found. This is a newly discovered species that does not have a scientific name yet. Many other organisms that do not have direct economic value like these potential pets, remain undetected.

Possible Solutions
There are a variety of strategies for managing species in decline. This video outlines possible solutions.
Managing endangered species is typically a community endeavor. Landowners, wildlife managers, conservation groups, and local governments attempt to balance priorities. In the Willamette Valley, the endangered Fender’s Blue Butterfly (Aricia icarioides fenderi) touches many people’s lives.
Artists play a critical role in educating the public about endangered species. This is a painting of a close-up view of the Fender’s Blue Butterfly wing.
The next section introduces microhabitats, including their importance to organism survival.
