Save the Date! 33rd Annual Landscape Symposium

Expanding the Scope of Landscape Design:
Ecology, People, & Time

Virtually held on:
Thursday and Friday, January 20 & 21, 2022
Thursday and Friday, January 27 & 28, 2022

1 – 4:30 PM EST
(includes instructional time & breaks)

Landscape designers who successfully employ an ecology-based approach typically draw from a variety of sources. The inextricable link between people and ecology only increases the need to broaden the investigative lens. Join us as we explore the integration of “ecology-based” design with “people-based” factors, including the lingering effects of historic land use and the need to accommodate diverse cultural perspectives on the meaning of “ecology.”

Featured speakers:

Raymond Jungles will discuss the work of world-famous modernist landscape designer, Roberto Burle Marx, and how his long association with Marx affected his own work.

W. Gary Smith will describe how environmental art has influenced his design practice, and how its immediacy can reflect natural processes of change in the landscape.

Robin Veder—Using the landscape designs of Beatrice Ferrand, Robin explores the kinesthetic experience people have when walking through her landscape at Dumbarton Oaks.

Gena Wirth, design principal at the firm SCAPE, works with cities, community advocates, and landowners to reveal the ecological and cultural potential of public landscapes.

Sara Zewde, founding principal of Studio Zewde, will discuss techniques her firm uses as they design enduring public places where people feel they belong.

Session Recordings! NDAL June – September Virtual Programs

Broadening Our Landscape Vision: Ecology, Culture, and Art
A Virtual Education Series

June – September 2021

Registration is open to view the recordings!

This summer, NDAL held a live series of programming organized in two tracks: 1) Professional Practitioners and 2) Home Gardeners, Educators, & Students. Registration is open to view these session recordings for three months after each live date.

Topics for professionals range from ecology-based landscape design, to culturally reflective landscapes, to the art of making “wild” landscapes legible. Larry Weaner also teaches a five-part intensive course on native design, planting, and management.

Join the room – virtually – for our Prairie-side Chat series as Larry Weaner interviews and compares notes with influential practitioners including Leslie Sauer & Tom Wessels.

Home gardeners and educators explore ways to create landscapes that are ecologically healthy, easily managed, and beautiful on residential and educational properties.

Students interested in the landscape field learn from Landscape Architect Ujijji Davis Williams & Landscape Designer and Contractor Larry Weaner about what it takes to enter the field, and the opportunities & challenges of starting a small landscape construction or maintenance business, particularly when few resources are available.

Demand for native meadows, particularly as an alternative to lawn, is increasing dramatically. That said, few planting types are more misunderstood, with many failures resulting from inadequate planning and the use of poorly adapted plants. Far better results can be obtained when the plants and processes used reflect the ecological character of our naturally occurring meadow communities. More than one-year wonders, meadows modeled on these ecosystems can provide long-term, easily managed landscapes that harbor a myriad of wildlife and provide color and texture throughout the year.

This in-person, all-day program will include indoor & outdoor components. Landscape Designer Larry Weaner will discuss the design, implementation, and management of native meadows. Landscape Designer Jenna Webster will explore important yet often lesser-known aspects of wildlife-sensitive meadow design and management methods, with an emphasis on birds and pollinators that rely on native meadow vegetation.
