Hudson Valley Natural Resource Mapper

The Natural Resource Mapper is an interactive tool to assist local land-use decision-makers in New York’s Hudson Valley with identifying and understanding important biological and water resources, the connections between them, and their broader regional context. By having information about natural features such as stream habitat, floodplains, wetlands, and large forests, communities can begin to identify priorities and strategies for their protection that can be incorporated into land-use and conservation planning. Ultimately, this process will help ensure that future generations continue to enjoy the numerous benefits of the Hudson Valley’s significant natural systems.

The mapper complements training, technical assistance, publications, and habitat and water resource summary reports provided by Hudson River Estuary Program staff. It can be used to support the development of natural resource inventories, open space plans, and watershed plans. Please visit other pages on this website for additional information about available maps and data for Hudson Valley municipalities and reports and publications providing guidance on local conservation tools and strategies. Links to additional online mapping tools are provided below.
