Conservation Flashcards
How will our current situtation with the number of species become a mass extinction?
If all the currently endangered and vulnerable species go extinct, we will be over 75% species extinct
What is the extinction vortex?
If a species gets to the point of a small enough population it is only a matter of time before they go extinct
What are different species classification systems?
CA’s species of special concern (state level)
Endangered Species Act (federal level)
CITES and IUCN Red List (international level)
What is eradication?
It is removing invasive species (introduced by humans) to protect native endagered ones
EX: frog population and sport fish
What is reintroduction?
It is saving a small population from the wild and breeding them effectively in captivity in order to recover the population until eventually releasing them back in the wild
Why are certain regions in danger?
Imperiled biodiversity is mainly caused by climate change and human development
Why is California a biodiversity hotspot?
It is due to the landscape complexity. Many different ecosystems.
What are reserves?
Protecting certain areas
Difficult due to economic/political limitations
What is the 30x30 CA initiative?
Protecting 30% of the land and coasts by 2030
ON TRACK!
What is fragmentation?
Habitats and environments usually broken up into smaller chunks due to human intervention
What is the point of connectivity?
Reduce fragmentation by protecting larger chunks of land with buffers
Building wildlife corridors and bridges
Removing human infrastructure (dams)
