Since 1981 Hudsonia has conducted environmental research, education, training and technical assistance to protect the natural heritage of the Hudson Valley and neighboring regions. A non-advocacy organization, Hudsonia serves as a neutral voice in the challenging process of land use decision making.

Our work includes education, basic and applied research on rare species and their habitats, wetlands and estuaries, and the study of invasive plants and other threats to biodiversity.
