Are non-native species all that bad, or are we just prejudiced against “the Other”? In the San Francisco Bay Area, one particular foreign species has been dividing environmentalists for years: the blue gum eucalyptus. Eucalyptus opponents say it’s a serious fire hazard. Defenders say there’s no good evidence it’s worse than native plants. Which is it? And is the fight against non-native species grounded in science or xenophobia? In this episode of Undiscovered, Annie and Elah investigate. 

 

GUESTS

FOOTNOTES

Read about the Bay Area’s eucalyptus debate.

Watch the debate between Norman and Dan in full, courtesy of Ray Madrigal.

Browse this website by a pro-eucalyptus activist and this page from the San Francisco Sierra Club, which wants to remove eucalyptus trees in some areas.

Invasion biologists defend their field and dispute allegations of xenophobia. Sara Kuebbing has also found that land managers aren’t arbitrarily eradicating non-native species, but selectively removing ones they deem harmful.

Mark Davis, a biologist who’s critical of invasion biology, covers some of the field’s history in his book, Invasion Biology.

And for a completely different perspective, check out these sources on the impacts of non-native species, including an early study that attempted a rough calculation of their global economic cost.
