Tejon Ranch is a 1000 km^2 home for California condors and an important biodiversity hotspot.
In 2008 the company agreed with environmental NGOs to preserve 90% of the property, including condor feeding grounds, while development could occur on the remaining 10%.
- Figure: Fact file on the California condor: California condors are scavengers and eat large amounts of carrion.
- They are among the world's rarest birds; 2012 counts estimated 405 total, including 226 wild and 179 captive.
- They are critically endangered and may travel up to 250 km in search of carrion.
- They mature and reproduce slowly, breeding at 6-8 years old and laying only one egg every two years.
- They are significant to many Californian Native American groups and traditional myths.
- Figure: Chumash cultural relationship with condors: Chumash people historically lived in central and southern coastal California; their descendants still live there.
- Old cave paintings show people wearing condor feathers for ceremonies and dances.
- Condors were once sacrificed during rituals; a legend says if the condor becomes extinct, so too will the Chumash.
Identify two arguments for the conservation of California condors.
intrinsic value of the species/biorights;
cultural value to Chumash and other Indians; future generations should have the right to see them;
a lot of money has been put into saving them so far, shame to waste it; role in ecosystem as clearing up carcasses; economic argument to attract ecotourists; one of the rarest species in the world, if we do not act now they will become extinct;
inspiring story - shows it can be done;
