2021 NDAL Annual Symposium

Registration is now OPEN for the Virtual 32nd Annual Ecological Landscape Symposium…

Guiding Theory into Reality:
It Don’t Mean a Thing if the Landscape Don’t Sing

The 2021 Ecological Landscape Design Symposium, going virtual this year, will explore how ecology, culture, and design can be incorporated into real-world contemporary practice. This program is geared toward landscape practitioners in the New England and Mid-Atlantic regions of the US.

January 21 & 22, 2021 | 1 – 4:30 PM EST*
January 28 & 29, 2021 | 9 AM – 12:30 PM EST*
*All four dates are distinct programs with different speakers – register for full bundle or individual days.

Incorporating science into landscape design is of little use if the resulting plantings are not harmonious to the people who engage with them, and are not in tune with the animals that depend on them. In this virtual symposium we will explore how scientific research can lead to tangible approaches for a new landscape tradition, one where ecological, anthropological, and sociological considerations expand the scope of landscape design.
