ONE NATURE INTEGRATES ECOLOGY AND ART TO CREATE LANDSCAPES THAT BENEFIT THE PLANET. We work at all scales, from large watershed studies to small residential gardens. Our projects are united by an adherence to place-based solutions and a commitment to environmental ethics.


Regenerative Design. We plan, design, and oversee construction of ecologically vibrant landscapes that have net positive environmental impacts.

Scientific Consulting. We work as field ecologists and botanists to monitor and evaluate landscapes of all types. Our scientists provide clear opinions and data that empower our clients to make land use decisions.

Landscape Construction & Stewardship (Maintenance). We build and care for landscapes in the Hudson Valley and beyond. We also support other constructors whose projects require technical expertise.

Native Plant Nursery. We have a two-acre, wholesale, native plant nursery located in the Hudson Valley where we grow native and edible species of herbaceous and woody plants. Our plant material is managed using more-than-organic practices.


One Nature is a CERTIFIED B CORPORATION. B Corp certification is to business what Fair Trade certification is to coffee or USDA Organic certification is to milk. B Corps are for-profit companies certified by the nonprofit B Lab to meet rigorous standards of social and environmental performance, accountability, and transparency. This means our clients can be sure their investment doesn't just go to making or protecting outstanding places, their dollars also support outstanding business practices.

Bryan Quinn is the founder and principal of One Nature. Technically trained in restoration ecology, environmental philosophy and landscape architecture, his vision is a world where our development activities improve the environment, rather than destroy it.

He holds a masters degree in Landscape Architecture from the Rhode Island School of Design, where he was a two-time winner of the prestigious Athena Award of Excellence. He also holds an undergraduate degree from Knox College and was honored recently by the college with an Alumni Achievement Award. Bryan lives with his wife and daughter in Beacon, NY. Prior to founding One Nature, he worked for New York City as a park designer/planner and, more recently, for leading ecological consulting & design firms. He has also been an adjunct professor at Pratt and the Rhode Island School of Design.
