Why a Maryland landscape architect restores brook trout habitat in his free time.

FROM THE AUGUST 2019 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

 

The underbelly of an eastern brook trout, especially when it is spawning, is orange and pink like a sunrise, and its back is dappled brown and green like a forest floor. The spots along its lateral line are small and circular like pink and yellow confetti, and the vermiculations on its back are yellowish and serpentine, like a Polynesian tattoo. It is a small fish, typically no longer than about 10 and a half inches—the height of this page—fully grown. It breeds in streams as far west as Minnesota and as far south as the extent of the Appalachian Mountains, in Georgia. First described in 1814, the species is thought to have come into its own during the Pliocene Epoch, between two million and five million years ago. Unlike the brown trout, which is commonly stocked for sportfishing, the brook trout is a member of the char genus. Both are members of the Salmonidae family, which also includes salmon.

The brook trout insists on cold water, and prefers to spend time in waterways with an even distribution of riffles and pools. When it is feeding, on plankton at first and later on insects as it matures, the fish wants to spend as little energy as possible to acquire food. It will hide in shadow in deep pools, and wait for bugs to come surfing down the thin seam of fast water that flows downstream from shallow rapids. If it senses an opportunity, it will strike. Sometimes it will catch a mayfly nymph, and sometimes it will catch an artificial fly tied to a fishing line owned by Scott Scarfone, ASLA. (more…)

A landscape architect and a biologist team up to counter urban biodiversity loss.

FROM THE JUNE 2019 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

 

A hawk glides overhead. An egret perches alongside a pedestrian walkway. Butterflies flutter in the foreground. From across the spectrum of the animal kingdom they appear in the drawings and renderings of modern architecture and landscape projects, hinting at a harmony between the designed space and the natural world. The projects, these animal cameos suggest, are not just urban developments, but healthy and diverse habitats.

“I won’t say it’s a lie, but these are big promises,” says Thomas Hauck, a Berlin-based landscape architect and a professor at the University of Kassel, in Germany. Hauck understands these images are meant to be aspirational, to show an idealized version of the designs they represent. But, he argues, sometimes too many illustrative liberties are taken “without evidence,” especially when urban development is more likely to destroy animal habitat than create it.

Hauck isn’t saying the animals should be taken out of the renderings. Rather, he wants to ensure animals actually show up once the project is built. To make that happen, Hauck has teamed up with a biologist from the Technical University of Munich named Wolfgang Weisser. Together, they’ve developed a theoretical design approach called Animal-Aided Design that seeks to counteract the ways development harms urban biodiversity by deliberately designing projects to accommodate animal species from the start. Through the careful targeting of species most likely to inhabit a given area, their approach provides the habitat requirements those species need to thrive throughout their life cycle.

“People hang up nest boxes and wonder why they’re empty,” Weisser says. “It’s because everything else is missing.” (more…)

INTRODUCTION BY STEVEN SPEARS, FASLA

FROM THE APRIL 2019 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

 

Regardless of your political perspective, we can probably all agree that 2016 was an interesting year for the nation. Since then, we have seen women participating in civic action and protest in unprecedented numbers. The midterm election of 2018 resulted in a wave of firsts: a historic number of women, LGBTQ leaders, and women of color breaking onto the national scene in politics not just as candidates but as victors.

A similar shift is happening in the practice of landscape architecture. In 2016 and 2017, four women—Gina Ford, FASLA; Cinda Gilliland, ASLA; Rebecca Leonard, ASLA; and Jamie Maslyn Larson, ASLA—all prominent, talented landscape architects and planners, broke away from their leading roles in award-winning firms to lead or start new practices. In October 2018, they held a panel discussion at the ASLA Annual Meeting on the challenges and opportunities of female leadership in the profession. At the same time, they jointly published a statement on change.org called the Women’s Landscape Equality (re)Solution. The statement outlines actions for creating a completely equitable professional environment for women in landscape architecture. (more…)

University of Virginia Landscape Architecture Chair Bradley Cantrell, ASLA, sees the future of landscape design as a spectrum of interactions between technologies that sense the environment, model and simulate it, and then finally affect the physical world—all without constant human input and monitoring. As argued in his March 13 LAM Lecture (and in his recent book Responsive Landscapes, written with Justine Holzman, ASLA), the future of landscape architecture is one of designing protocols for how natural systems behave, and tuning these algorithms and eventually the land itself, thus loosening the stranglehold static and monofunctional infrastructure has on the planet.  “It’s not about us controlling every aspect,” he says. “It’s about us setting a range of ways those behaviors can act within.”

Cantrell’s research is grounded in the previous century’s cutting-edge modeling and simulation methods, like the Army Corp of Engineers Mississippi River Basin Model in Clinton, Mississippi, which modeled the entire rivershed, scaled down to a mere 200 acres. From there, Cantrell details contemporary research that is equal parts computational and material, honing ever more granular data points toward more accurate models. For example, there’s USC Assistant Professor Alexander Robinson’s Office of Outdoor Research, Landscape Morphologies Lab work, which uses an articulated robot arm to scrape out dust-mitigating landforms at California’s Owens Lake. Cantrell’s own inquiries involve test bed river basin models that deposit sediment via the variable flow of water, which he has been able to manipulate as though it were a geologic 3-D printer, expanding and cutting back sediment deposit “land” where it’s desired. The resulting topographies are scanned and converted into point-cloud maps.

Cantrell’s approach pushes landscape architecture’s prevailing infrastructure fixation until it ricochets out of the physically imposing world of concrete and culverts and into abstract data, underpinning the omnipresent ways we reengineer ecologies with quantitative facts. The biggest challenge for modeling and simulating dynamic environments, Cantrell says, is not gathering all the requisite data, but getting it to interact in a way that matches reality. At its core, it’s a call for new levels of observational rigor: first, to observe all the factors that make an ecosystem function, and then to understand how those factors work together to create a landscape.

From We Declare in the May 2016 issue, five landscape architects, scholars, and advocates revisit “A Declaration of Concern” for the Landscape Architecture Foundation’s 50th anniversary celebration.

 

FIFTY YEARS OF THE DECLARATION: EVOLUTION AND PROSPECTS

BY MARIO SCHJETNAN, FASLA

The 1966 Declaration of the Landscape Architecture Foundation established very clearly the group’s concern about the poor environmental conditions, social inequalities, and loss of quality of life prevalent in most North American cities around that time. It was a timely and valorous call, an outcry and a moral declaration by landscape architecture leaders of their time.

To be honest, many U.S. cities have in these 50 years upgraded their levels of air quality, decreased their contamination of soils and water, and improved their public open spaces. Many of these cities have rehabilitated and repopulated their city centers and enhanced habitability in general.

However, many other challenges and global concerns have now arisen, including climate change, the horizontal expansion of cities, and, in the United States, still the highest levels in consumption per person of natural resources, energy, land, and water in the world.

Fifty years ago in Latin America, there were very few landscape architects and not a single (more…)

After two years of construction, St. Patrick’s Island Park in Calgary, Canada, by Civitas and W Architecture & Landscape Architecture, recently opened to the public. In these two short videos by Civitas, some of the project designers talk about the main components of the project, such as a tall hill called the Rise that opens views of downtown Calgary and doubles as a giant sledding hill in the winter, and why they are so important to creating the island oasis at the heart of the city. A large path, called the Transect, cuts across the island through four different ecosystems, creating a strong architectural element in the design, and acts as the stage for a bike-cam spin through the park in the second video.

Little-loved plants win the affection of Future Green Studio.

Little-loved plants win the affection of Future Green Studio.

From the September 2015 issue of Landscape Architecture Magazine.

The huge backyard along the Gowanus Canal in Brooklyn was the perfect site for the summertime Sunday afternoon parties that the DJs Justin Carter and Eamon Harkin liked to throw. It had plenty of space, room for a bar, and the overgrowth that comes alongside New York’s lovable Superfund waterway. But they had only temporary leases and permits to throw parties. Their time in the huge backyard wouldn’t last forever.

Carter and Harkin went looking for a permanent home and found something similar: a garbage-strewn industrial lot covered in weeds next to the L tracks in Ridgewood, Queens, a few miles away. “When we found it, it was, like, kind of just a junk heap,” Carter says.

Carter called David Seiter, ASLA, the principal and the design director at Future Green Studio, a landscape design and urban ecology firm of about 20 people then based close to the party space along the Gowanus. Seiter and his studio had also warmed to the area’s unkempt feeling and wanted to keep (more…)
