Reserve-sponsored research focuses on understanding the aquatic habitats of the Hudson River Estuary and on generating the information necessary for management and protection of the estuary. Research staff and partners conduct estuarine research studies of ecosystem processes, exchanges between wetlands and the Hudson’s main stem, and physical, biological, and chemical characterizations. Research protocols are adapted primarily through the NERRS System-Wide Monitoring Program (SWMP) to analyze water quality, nutrient, and meteorological conditions; to map critical estuarine habitats; and to assess the impacts of climate change stressors through a Sentinel Site network. All NERRS data-sets, science products and results are publicly available through the Centralized Data Management Office website.

Additional research opportunities are provided through two fellowship programs co-sponsored by the Reserve, including the NERRS Graduate Research Fellowship (GRF) and the Tibor T. Polgar Fellowship. These fellowships provide financial support for graduate and undergraduate students to conduct research in the Reserve sites and have generated well over 150 student research projects in the past 25 years. Recent NERRS GRF recipients include Christopher Nack (2010 – 2011) from SUNY College of Environmental Science and Forestry, whose project was entitled “Habitat Use by American Shad Larvae in the Hudson River Estuary, NY,” and Brian Brigham (2010 – 2012) from Queens College CUNY, whose project was entitled “Exploring Biogeochemical Connections Between Anthropogenic Nutrient Deposition and the Anaerobic Production of Hydrogen Sulfide in Wetland Systems.”


River Bottom Mapping

In 1996 the New York State Department of Environmental Conservation (NYSDEC) initiated the River Bottom Mapping Project, an effort to map the river bottom habitat of the Hudson River Estuary as part of a larger Hudson River Action Plan. This project includes extensive mapping using sidescan sonar, sub-bottom profiling, single and multi-beam bathymetric sonar, as well as collecting ground truth data with sediment cores, grab samples, and sediment profiling imagery (SPI)…learn more about River Bottom Mapping

System-Wide Monitoring Program

Protocols of the NERRS System-Wide Monitoring Program were implemented to analyze the long-term change and short-term variability of nutrient, water quality, and meteorological conditions … learn more about the System-Wide Monitoring Program

Habitat Mapping

The Research Reserve has partnered with The Cornell University Institute for Resource Information Systems (IRIS) to interpret aerial photographs for vegetative cover type and to produce several habitat mapping products as GIS layers … learn more about Habitat Mapping

Sentinel Site for Climate Change Research

The Reserve has initiated a long-term study that will establish the Tivoli Bays as a NERRS Sentinel Site for assessing the impact of climate change stressors on estuaries.  The goal of this study is to evaluate the ecological impacts of sea level change and increased storm surges on submerged aquatic vegetation and emergent tidal marsh habitats …learn more about Climate Change Research

Dams and Sediment in the Hudson

A collaborative project started in 2016 to quantify the effect of removing dams in the tributaries of the Hudson River watershed on sediment movement, with a particular focus on how that sediment movement would impact tidal wetland health in the face of a changing climate …learn more about Dams and Sediment in the Hudson

Tivoli Bays Launch Closure – 2019

The canoe and kayak launch on the Kidd Lane access road at Tivoli Bays WMA is closed for renovations until further notice. At this time, DEC does not have an estimated completion date for the project. Please contact Nathan Ermer at 845-256-3047 for more information about this project. Thank you for your patience and understanding.
