Founded in 1990 by Landscape Designer Larry Weaner and NDAL, this annual two-day symposium has a long tradition of celebrating native plants and innovative ecological practice. Presenters reflect the diverse factors that shape our landscapes including landscape architects, landscape designers, horticulturists, ecologists, historians, anthropologists, artists and others. The series offers in-depth explorations of forward-looking and overlooked topics, always seeking to connect theory with practical application. Join us as we continue to connect the dots between ecological restoration, cultural landscape practice, and fine garden design.
Special Note: For many years, NDAL has deeply appreciated its partnership with Morris Arboretum of the University of Pennsylvania and Connecticut College Arboretum in jointly presenting the January Annual Symposium. While NDAL will be solely producing the Symposium from this year onward, we would like to gratefully acknowledge the important role these two institutions and their respective team members have played.
The 2026 symposium, January 15 and 16, is Seeing the Forest AND the Trees: Designing Landscapes that Integrate Regional Specificity with Global Commonality. Incorporating a region’s indigenous plant communities and ecological processes is at the heart of ecology-based design. But no natural system operates in isolation or is forever immune to change…..especially today where the effects of watershed alteration, soil disturbance, plant globalization, and climate change are at play worldwide. Our Symposium will begin by zooming in on techniques for regionally-specific landscape analysis and design. We will then widen the lens and learn how disturbance, ecological science, and cultural land practices across regions can factor into those processes. Finally, we will explore how an expansive view of landscape art can unify this micro/macro divide in landscapes ranging from expansive to intimate.
The event takes place at Kean University in Union, New Jersey, but there are virtual options available. Early bird registration savings available through December 10. Register at https://www.ndal.org/2026-annual-symposium
