Hudsonia employs a staff, is directed and advised by its boards, and relies on the assistance of its research associates.


Erik Kiviat, PhD, Executive Director. A lifelong resident of the Hudson Valley and a Hudsonia co-founder, Erik has studied the plants and animals of the region for 45 years and has authored or co-authored 80 publications and 200 technical assistance reports on wetland ecology, rare species conservation, habitat ecology, introduced species, the Hudson River, and other subjects. Erik is the author of The Northern Shawangunks: An Ecological Survey; Hudson River East Bank Natural Areas; and Hackensack Meadowlands, New Jersey, Biodiversity: A Review and Synthesis. He is a Certified Wetland Scientist.
See Erik’s résumé here.

Chris Graham, MS, Field Botanist. Chris’ background is in plant community ecology. His master’s degree research investigated the effects of large herbivore extirpation on seed survival and woody seedling communities in tropical forest fragments, with implications for future canopy tree community composition. At Hudsonia, Chris works on habitat mapping projects and on floristic surveys. He is interested in rare species conservation, community description and classification, and the effects of resource extraction and global change on plant communities, among other topics.

Robert E. Schmidt, PhD, Associate Director. He is retired from teaching for many years at Bard College at Simon’s Rock in Great Barrington, Massachusetts. Bob’s long experience in ecology and natural history focuses on aquatic and estuarine habitats, fish, invertebrates, and nonnative species. He has conducted research in rural and urban stream systems, the Hudson River and Mohawk River, waterways of New England, and in the Neotropics.

Gretchen Stevens, BS, Director of the Biodiversity Resources Center. Gretchen has 35 years experience in remote sensing, habitat assessments, habitat mapping, rare plant surveys, and other field biology in the Northeast and elsewhere in the U.S. She is co-author of the Biodiversity Manual for the Hudson River Estuary Corridor and A Beginner’s Guide to Wild Flowers of the Northeast, and has authored numerous technical reports on biological assessments, rare plant surveys, and other subjects. Gretchen manages the GIS laboratory at Hudsonia, curates the Bard College Field Station Herbarium, and supervises the Habitat Mapping Program and the Biodiversity Education Program of the BRC.

Lea Stickle, BS, Administrative Director and Research Assistant. Lea came to Hudsonia as an intern, sampling bryophytes associated with co–occurring purple loosestrife and swamp loosestrife. Since joining Hudsonia Lea has worked on various projects, such as studying the response of a bog turtle population to habitat management and surveying wetland flora at Thompson Pond.
