2020 NDAL Annual Symposium

Thank you for a wonderful 31st Annual Landscape Symposium!

Jan. 9-10, 2020 | Bryn Mawr College, Bryn Mawr, PA | Cosponsored by Morris Arboretum of the University of Pennsylvania

Jan. 16-17, 2020 | Connecticut College, New London, CT | Cosponsored by Connecticut College Arboretum

Culture and ecology exist in a dynamic relationship: culture shapes ecology and vice versa.  Our 2020 conference will explore this feedback loop as it pertains to landscape design and management.  From historical as well as contemporary perspectives, our presenters will consider the complex, sometimes overlooked ways in which culture and ecology interact and what this means for how ecology-based design can be most effective.
