About Putnam Valley’s Natural Resources Inventory

The Natural Resources Inventory (NRI) compiles and describes important, naturally occurring resources that enrich the town of Putnam Valley. Our wetlands, forests, streams, and shrublands house abundant wildlife and native plants, and these habitats provide vital benefits to people as well. These ecosystems help to moderate temperature, filter pollutants, keep drinking water and air clean, absorb floodwaters, and allow for pollination of agricultural crops. These ecosystems, along with our historic sites, present opportunities for outdoor recreation and education and create the scenery and sense of place that is unique to our town.

The upcoming NRI will provide the building blocks for comprehensive land-use and conservation planning. The NRI provides our community with a strong and current foundation for informed, proactive strategizing at every level of decision-making. The Putnam Valley Commission for Conservation of the Environment (CCE), along with a group of dedicated Putnam Valley resident volunteers, prepared the NRI with technical support from the Hudson Highlands Land Trust (HHLT) and the New York State Department of Environmental Conservation Hudson River Estuary Program. This work was part of a partnership project between HHLT and Cornell University Department of Natural Resources, with funding from the Environmental Protection Fund through the New York State Department of Environmental Conservation Hudson River Estuary Program. The CCE is responsible for developing and maintaining an NRI under the Putnam Valley Town Code and NY State General Municipal Law.

The CCE encourages community participation in further identifying and prioritizing these natural resources. Putnam Valley can preserve our natural and historical heritage and ensure that healthy, resilient ecosystems—and the benefits they provide—remain available to our community for future generations.

Section 8-23.A.(3) of the Town Code of Putnam Valley requires the CCE to “conduct studies, surveys and inventories of the natural and man-made features within the Town of Putnam Valley” and to maintain an up-to-date inventory of all open spaces within the town’s boundaries. New York State enabling law for municipal conservation advisory councils (CCE is one) also provides in General Municipal Law Section 239-x that an NRI be developed and maintained by the local conservation advisory council.

The NRI Document

The NRI (Natural Resources Inventory) is a large document containing text and maps that were prepared to update and supplement the Town's Master Plan that was written in 2007. The entire NRI can be downloaded here: Putnam Valley NRI. The CCE urges everyone to read the NRI in its entirety.

The NRI can be downloaded by chapter. Each chapter file (PDF format) included the text and the accompanying maps.
