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

FROM THE MARCH 2018 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

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…)

In Owens Lake, a land art installation draws on 100-year-old history while providing critical habitat.

FROM THE FEBRUARY 2017 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

When NUVIS Landscape Architecture was hired to assist the Los Angeles Department of Water and Power (LADWP) with its dust mitigation effort at Owens Lake (see “Dust to Bust,” LAM, October 2012), Perry Cardoza, ASLA, was given a list of objectives. Foremost, any design needed to tamp down the dust that had become a public health hazard, but it also would have to meet very specific habitat goals and help the department meet its water-use reduction targets. (LADWP has used up to 95,000 acre-feet of water annually for dust mitigation.) What was not on the list was any mention of land art.

“In everyone’s mind, this was going to be a hiking trail with a parking lot,” says Cardoza, an executive vice president at NUVIS. “We would have gravel and wetlands and some salt grass, and [we] would call it a day.” The project evolved, however, and the completed landscape, which opened to the public in April 2016 and won an Award of Excellence from the ASLA Southern California Chapter the same year, falls right into the land art tradition, even as it fulfills its mandate as an ecological booster.

Located on a tiny parcel—at 700 acres, the parcel is still just 1 percent of the lake’s total area—near the lake’s northeast boundary, the design includes a monument-like shade structure and a series of plazas and interpretive kiosks that are connected by four miles of walking paths. For Cardoza, what pushes the work into the realm of land art are its 14 (more…)

A new firm in L.A. thinks it’s time to turn up the volume on landscape architecture.

A new firm in L.A. thinks it’s time to turn up the volume on landscape architecture.

From the August 2016 issue of Landscape Architecture Magazine.

Earlier this spring, Kelly Majewski, Affiliate ASLA, was one of more than 100 designers in Los Angeles who attended Design for Dignity, a one-day “congress” convened by the L.A. chapter of the American Institute of Architects (AIA) to identify ways to alleviate the city’s homeless crisis. But for Majewski, a landscape designer, the takeaway may not have been what the organizers hoped. “I got asked by multiple architects, once they found out I did landscape architecture, what I was doing at this conference,” she says. “I heard it three times. Which just blows my mind.”

Majewski founded Superjacent, a new landscape architecture and urban design studio, with Tony Paradowski and Chris Torres in January 2016. And it’s interactions like those at the AIA conference that inspired (more…)
