State of the Estuary

Understanding the changing conditions of the Hudson River and Harbor Estuary requires a complex set of indicators. The quality of the water, the health of fish and wildlife, the amount and location of public access and the engagement of residents in stewardship activities tell us about these ecosystems and management needs.

State of the Estuary Report

The NY-NJ Harbor and Estuary Program has developed a new State of the Estuary Report for 2018. This report is organized by HEP’s five goals: water quality, habitat and ecological health, port and maritime, public access and stewardship, and community engagement.

In 2015, the NYS DEC Hudson River Estuary Program created a State of the Hudson Report:

Environmental Monitoring Plan

Environmental monitoring is critical for tracking the health of the estuary, and the progress and effectiveness of management actions. To help coordinate these monitoring efforts, improve data analysis, and make data available, the NY-NJ Harbor and Estuary Program has produced an Environmental Monitoring Plan for 2018. There are three tools: a monitoring inventory and interactive map, a companion digital storymap, and a research and monitoring recommendations report.
