Linked Ecologies: The Bronx River and the Thain Family Forest

April 14, 2026

4 to 5 p.m. | Mertz Library

A Conversation between Daniel Willner and Todd Forrest

At the heart of the New York Botanical Garden, the Thain Family Forest rises above the Bronx River Gorge. The river and the forest have been shaped by nature for millennia, but for several hundred years, these two intertwined ecosystems have been ever more shaped by culture. Facing serious challenges, both the forest and the river represent significant achievements in environmental protection and remediation.

In this talk, Daniel Willner will explore the work he did as the 2025 Larry Lederman Photography Fellow drawing from over two decades of experience documenting the ordinary and extraordinary landscapes of the Lower Hudson Valley. Joined in conversation by NYBG’s Vice President for Horticulture and Living Collections, Todd Forrest, Willner will explain how he has followed the Bronx River and the Thain Family Forest through the seasons, offering a year-long interpretation of the beauty and value of these two urban landscapes.

Daniel Willner fell in love with photography and nature while exploring the wild edges of town with his father’s camera. He continued his studies in photography at Oberlin College and Columbia University, where he received his MFA in 2007. His multiyear study of the Great Swamp, a 6,000-acre wetland stretching from Westchester to Dutchess County, resulted in multiple exhibits and supporting grants from the Puffin Foundation, Collaborative Concepts, and Arts Westchester. He continues to explore this territory, photographing reservoir infrastructure, portraits of native plants, and panoramic studies of vernal pools, forest streams, and other upland water sources within the reservoir system. He is a Westchester resident and an instructor of photography in the Department of Visual Arts at Fordham University.
