Two closely related Asian beetles are boring their way through Southern California’s trees.

Smaller than sesame seeds, two beetle species are spreading through Southern California, killing hundreds of thousands of trees and infecting many thousands more with a pathogenic fungus.

At first, scientists thought the pests were the same species because they look exactly alike, but they carry different pathogenic fungi, and DNA analysis revealed genetic differences. But their damage to trees is so spectacularly similar that the two beetles—the polyphagous shot hole borer and the Kuroshio shot hole borer—are now referred to collectively as the invasive shot hole borer (ISHB).

A 2017 U.S. Forest Service survey estimated that 23 million trees are vulnerable to the ISHB that is working its way through Los Angeles, Orange, Riverside, and San Bernardino Counties—or 33 percent of Southern California’s urban canopy. It’s impossible to know how many trees will die, but the projected losses are catastrophic. (more…)

It’s complex, civic-minded work built out of decades of engagement in the community.

So it’s somewhat unexpected to see some of Studio-MLA’s recent work (more…)
