Billion Oyster Project Partnership

The Nature Conservancy and Billion Oyster Project partner to restore the health of New York Harbor.

The Nature Conservancy's dedication to marine protection in New York is longstanding. The Conservancy launched its first U.S. marine project in New York off the shores of Long Island and currently operates 100 marine projects worldwide. The Nature Conservancy in New York is working to restore harbor health to help create a healthy, thriving New York Harbor. 

Why Oysters?

  • Globally, a staggering 85 percent of oyster reefs have been lost in the last 200 years. Factors including pollution, disease, overharvesting, drought and habitat loss have made oyster reefs the single most imperiled marine habitat on the planet. In fact, oyster beds once covered most of the Hudson-Raritan Estuary, but today’s populations are less than 0.01% what they once were in New York Harbor.
  • Oysters are incredible water filters. One adult oyster can filter as much as 50 gallons of water a day; a healthy one-acre reef filters approximately 24 million gallons of water daily. Beyond filtering water, oysters create habitat for other animals, which is necessary to a robust harbor ecosystem.

What We Are Doing

Since 2016, The Nature Conservancy has partnered with the Billion Oyster Project whose objective is to restore oyster reefs to New York Harbor through public education initiatives. To date, the organization has planted over 28 million oysters, and collected and recycled one million pounds of shell. The Nature Conservancy provides scientific and technical expertise to characterize impacts, understand challenges and improve outcomes. Together, the organizations work to improve the health of New York Harbor.

Comprehensive evaluations of ecological restoration projects can take many years. Yet initial research is beginning to provide new and useful insights into the performance of restoration across the Harbor. The Nature Conservancy has released several reports in collaboration with Billion Oyster Project including: 

Our work provides a greater understanding of restoring harbor health in an urban setting and will be shared with restoration practitioners in New York City and experts in coastal cities across the globe. It is only the beginning of this effort, and long-term research and restoration is critical to the health of New York Harbor and our communities.
