In a session at the Society for Ecological Restoration (SER) conference in Madison, Wisconsin, ecologist John Munro worried that SER is moving away from its focus on practical, on-the-ground, ecological restoration projects in favor of more passive, “academic research on restoration ecology.” Pointing to Temple University’s landscape architecture and horticulture program, which features the first ever-accredited concentration in ecological restoration, he said the focus must remain on “doing rather than studying.” His fear is that many restoration ecologists can no longer “see the forest for the statistics.”
The solution, according to Munro, is to boost ecological site design education in both landscape architecture and ecology degree programs. Landscape architects and restoration ecologists must understand “specifications, logistics, sequencing, planning. This can’t be handed to other professions.” A landscape architect in Philadelphia discussed the ecological issues landscape architects must increasingly know about. A landscape architect professor and graduates from the Temple program then discussed their innovative program and what they are doing with what they’ve learned.
Landscape Architects Need Ecological Know-How
According to Emily McCoy, ASLA, Andropogon, “landscape architects are finally beginning to take seriously the idea of measuring ecosystem function.” They are also beginning to “take the best scientific information and apply them to landscape design.” This is challenging because landscape architects are not trained in statistics so can’t truly understand landscape function. This means they need to work with restoration ecologists or environmental designers.
Andropogon, one of the most cutting-edge landscape architecture firms in terms of sustainable design, has actually created an “integrative research department” to help incorporate the latest research into their practice. “We are focused on collecting adaptive feedback. We want to apply the latest data on landscape performance.” The firm is doing this because they believe all the new research can support their mission of improving the “health, safety, and welfare of people.” Andropogon thinks “urban environments can positively contribute to our health.”
McCoy identified a number of research areas where Andropogon says they need help from restoration ecologists or landscape architects trained in ecology. They are soils and soil biology (here, they are interested in “how what’s under the ground affects what’s above the ground”); habitat (“how do we define this?”); native plants (“can they succeed on green roofs?”); climate change; urban heat islands; assisted migration; and plant provenance and ecotypes. They need this kind of research for their sustainable landscape projects, like the green roof for the new U.S. Coast Guard headquarters in Washington, D.C., which features native plant communities and now attracts wildlife (see image above).
She also said the Sustainable Sites Initiative™ (SITES®), a kind of “LEED for Landscapes,” will further boost demand for ecological research services among all landscape architects. “SITES asks what is the habitat value? How do you measure performance of plants and soils in man-made landscapes?” Right now, data on ecosystem services provided by urban landscapes is largely unavailable.
Learning How to Do Ecological Restoration
Mary Myers, FASLA, professor of landscape architecture at Temple University, said Temple has the only accredited landscape architecture program with a concentration in ecological restoration. She defined landscape architecture as an “environmentally-focused profession whose mission is to promote environmental balance and human well-being through sustainable design.”
To get similar programs going in other landscape architecture departments, she advised academic program chairs to “build lateral support within and out universities, get other environmental design schools on campus involved, and bring in expert outside advisers.” At Temple, Myers brought in Andropogon Associates, BioHabitats, and Mark Focht, FASLA, first deputy commissioner, Philadelphia Parks and Recreation.
To build the case for the new program, which she did as chair of the landscape architecture and horticulture department, she pointed to U.S. Labor and ASLA reports outlining booming job growth for landscape architecture and ecological restoration, along with a U.S. News and World Report article that said ecological restoration is a growing field.
Myer’s program applies ecosystem design. There are modules on woodlands and wetlands, with classes on technical engineering and ecosystem design spread throughout. The third year has a special “public lands module,” and a capstone project in the field. Myers made a point of emphasizing how important “graphic communication” was in the curriculum, too, which was accredited by LAAB in 2013.
How Temple University Students Approach Ecological Restoration
A group of Temple University graduates as well as current students then discussed how they are approaching ecological restoration in their work and studies. Sara Street, Construction Specialties, Inc. (C/S), a Temple University landscape architecture and ecological restoration graduate, described C/S’s efforts in designing a sustainable corporate campus for their sales office in Muncy, Pennsylvania. Located on the west branch of the Susquehanna River, the corporate campus is an industrially-zoned site in a region with a long history of human habitation. The campus’s new design includes stormwater capture and reuse, a reintroduction of native plants (including a native vegetation propagation facility), and a new trail system. Street described how the project will serve as an educational facility for local school children, teaching them about ecological restoration.
Street stressed the need for a quantifiable, objective method for judging ecological restoration projects. C/S’s new campus will be highly monitored over time. As landscape architecture and ecological restoration projects become more intertwined, Street expressed optimism for the development of new standardized system of sustainability scorecards.
Patricia Kemper, Master of Landscape Architecture Candidate, Temple University, then discussed the integration of landscape architecture and ecological restoration. She cited several built examples, including the James Clarkson Environmental Discovery Center in White Lake Township, Michigan. Completed in 2008, the project – a recipient of an ASLA 2008 Professional General Design Honor Award – involved a large-scale ecological restoration effort. MSI Design led a multidisciplinary team to accomplish this task, which required the reintroduction of 170 native plant species, the preservation of existing wetlands and woodlands, and a new ecologically-managed stormwater system. Furthermore, an underwater plexiglass classroom entices school children to learn about the aquatic ecology of the site. By merging landscape architecture and ecological restoration, the design of the James Clarkson Environmental Discover Center benefits both wildlife and the public.
Kemper followed her case studies with the results of a survey of universities with master programs in landscape architecture. Respondents were asked questions regarding the role of ecological restoration education in their landscape architecture programs. She found that while landscape students are getting exposed to the concepts of ecological restoration, they are not typically being taught nuts and bolts of ecological restoration practice. More emphasis on ecological restoration in landscape architecture education is needed.
Sue Ann Alleger, who graduated with a Master’s of Landscape Architecture degree from Temple University, then reiterating the importance of dual training in landscape architecture and ecological restoration. Alleger outlined how pressures from widespread urbanization, population expansion, and climate change are disrupting environmental systems. In this context, she felt ecological restoration should play a part in any landscape design. She described how ecological restoration is coupled with design projects at Temple University, from inventory to analysis, concept, and final plan. For example, design projects can involve an extensive site inventory of quantitative and qualitative data, which is plotted and compared to a reference model.
According to Alleger, this kind of technical rigor extends to every stage of a design project at Temple University, integrating ecological science with design at all points. Whether or not Temple’s model of merging landscape architecture and ecological restoration becomes more widespread, further collaboration between these two disciplines will be increasingly important as ecological performance is demanded of our landscapes.
