The '''Billion Oyster Project''' is a New York City-based nonprofit organization with the goal of engaging one million people in the effort to restore one billion oysters to New York Harbor by 2035. Because oysters are filter feeders, they serve as a natural water filter, with a number of beneficial effects for the ecosystem.<ref>{{Cite web|title=Oyster Fact Sheet|url=https://www.billionoysterproject.org/ecosystem-engineers|access-date=2023-02-24|website=www.billionoysterproject.org}}</ref> The reefs they form increase habitat and subsequent marine biodiversity levels,<ref>{{Cite web|last=Fisheries|first=NOAA|date=2021-10-26|title=Oyster Reef Habitat {{!}} NOAA Fisheries|url=https://www.fisheries.noaa.gov/national/habitat-conservation/oyster-reef-habitat|access-date=2022-02-02|website=NOAA|language=en}}</ref> and help protect the city's shorelines from storm surges.<ref>{{Cite web|last1=Matchar|first1=Emily|date=10 January 2018|title=As Storms Get Bigger, Oyster Reefs Can Help Protect Shorelines|url=https://www.smithsonianmag.com/innovation/storms-get-bigger-oyster-reefs-can-help-protect-shorelines-180967774/|access-date=2022-02-02|website=Smithsonian Magazine|language=en}}</ref>

The Billion Oyster Project believes that engaging community members—especially young people—in reef restoration will lead them to become more environmentally aware in the future. The project aims to engage hundreds of thousands of students, teachers, and community scientists in marine restoration-based STEM educational programming. It involves 80 restaurants in an oyster shell recycling program,<ref name='ched'>{{cite news |title=The Billion Oyster Army Saving New York Harbor From Itself |url=https://www.youtube.com/watch?v=kinmq0UPizg |access-date=15 December 2025 |publisher=Cheddar |author=Chris Castellino |date=11 December 2025}}</ref> which provides the project with shells for building new reefs.

The project grew out of the activities of students at the New York Harbor School, as of 2025 located on Governors Island,<ref name='ched' /> who started growing and restoring oysters in New York Harbor in 2008. The school continues to be the project’s main educational partnership, involving students through internships and waterfront experience in seven Career and Technical Education (CTE) programs.<ref>{{Cite web|title=CTE_PROGRAMS|url=https://www.newyorkharborschool.org/cte_programs.html|access-date=2022-02-02|website=www.newyorkharborschool.org}}</ref> Along with Harbor School, the Billion Oyster Project is stationed on Governors Island and the scope of their work is confined to the five boroughs of New York City.<ref>{{Cite web|title=Billion Oyster Project|url=https://www.billionoysterproject.org/|access-date=2022-02-02|website=Billion Oyster Project|language=en-US}}</ref>

== History == Oyster reefs in New York City are thought to have covered more than {{convert|220000|acres|km2}} of the Hudson River estuary and filtered water, provided habitat for other marine species, and attenuated wave energy, but are now functionally extinct in the Harbor due to overharvesting, dredging, and pollution.<ref>{{cite news|url=http://www.villagevoice.com/restaurants/a-billion-oysters-tell-the-history-of-new-york-7212289 |archive-url=https://web.archive.org/web/20150618235952/http://www.villagevoice.com/restaurants/a-billion-oysters-tell-the-history-of-new-york-7212289 |url-status=dead |archive-date=June 18, 2015 |author=Karen Tedesco |title=A Billion Oysters Tell the History of New York|work=The Village Voice| date=1 June 2015}}</ref>

The initiative was the brainchild of Murray Fisher and Pete Malinowski, and grew out of the Urban Assembly New York Harbor School in 2014. A $5 million National Science Foundation grant allowed the program to spread to thousands of public middle school students starting in 2015.<ref>{{cite news |url=http://www.dnainfo.com/new-york/20141030/south-street-seaport/billion-oysters-project-5m-grant-used-build-new-marine-based-curriculum |author=Sybile Penhirin |title=Billion Oysters Project $5M Grant |publisher=DNAinfoNY |date=October 30, 2014 |url-status=dead |archiveurl=https://web.archive.org/web/20150923231143/http://www.dnainfo.com/new-york/20141030/south-street-seaport/billion-oysters-project-5m-grant-used-build-new-marine-based-curriculum |archivedate=September 23, 2015 }}</ref>

Location is the Bronx side of the East River, approximately 1 mile west of the Whitestone Bridge (visible in background).]] As of December 2025, more than 150 million oysters had been restored to New York Harbor, with {{convert|17|acre|m2}} of reef area restored.<ref name='ched' /> More than 11,000 high-school and middle-school students have taken part in the project. Approximately {{convert|2,000,000|lbs|t|abbr=off|sp=us}} of oyster shell have been recycled. In 2020, expansion into mobile spawning tanks at Red Hook, Brooklyn, allowed for significant increases in capacity.<ref>{{Cite web|last=Ramirez|first=Jeanine|date=24 July 2020|title=Shipping Containers Turned into Oyster Tanks in Brooklyn|url=https://www.ny1.com/nyc/brooklyn/news/2020/07/24/shipping-containers-turned-into-oyster-tanks-in-brooklyn|access-date=2020-08-05|website=www.ny1.com|language=en}}</ref>

== Projects == === Living Breakwaters === Living Breakwaters is a project overseen by the Billion Oyster Project in Staten Island intended to reintroduce oysters while also protecting against storm surge, increasing biodiversity, improving water quality, and creating educational opportunities. This project is funded in part by the United States Department of Housing and Urban Development, which contributed $60 million partly for the purpose of disaster recovery from Hurricane Sandy, but also to prevent similar disasters in the future. Staten Island was greatly affected by erosion and flooding from the 2012 storm, particularly along the south shore.<ref name="Wattles">{{cite web |last1=Wattles |first1=Jackie |title=Cleaning New York's filthy harbor with one billion oysters |date=16 January 2019 |url=https://www.cnn.com/2019/01/16/tech/billion-oyster-project/index.html |publisher=CNN |accessdate=2019-11-20}}</ref>

The project started in Tottenville, a neighborhood once famous for its oyster population.<ref name="Rebuild by Design">{{Cite web |title=Living Breakwaters |url=http://www.rebuildbydesign.org/our-work/all-proposals/winning-projects/ny-living-breakwaters |url-status=dead |archive-url=https://web.archive.org/web/20220127014319/http://www.rebuildbydesign.org/our-work/all-proposals/winning-projects/ny-living-breakwaters |archive-date=2022-01-27 |access-date=2019-11-20 |website=Rebuild by Design}}</ref> As part of the strategy, discarded oyster shells from over 70 New York restaurants are collected and left outside for a year to be naturally cleansed of organic matter. Baby oysters are then placed on the shells by students at New York Harbor School, a maritime-focused public high school located on Governors Island.<ref name="Wattles" /> The oyster larvae are of the currently existing population, rather than introducing those of other populations, which runs the risk of also introducing invasive species.<ref>{{cite web |last1=Michelle |first1=Cohen |title=Living Breakwaters: An Award-Winning Project Brings 'Oyster-tecture' to the Shores of Staten Island |url=https://www.6sqft.com/living-breakwaters-an-award-winning-project-brings-oyster-tecture-to-the-shores-of-staten-island/ |website=6sqft |date=28 January 2015 |accessdate=2019-11-20}}</ref> The oysters will be placed onto several walls in the water made of low-acidity permeable concrete.<ref name="City Lab">{{cite news |last1=Appelbaum |first1=Alec |title=New York's Big Climate Plan Really Does Include Oysters |url=https://www.citylab.com/environment/2015/12/new-yorks-big-climate-plan-really-does-include-oysters/419847/ |newspaper=Bloomberg.com |date=15 December 2015 |accessdate=2019-11-20}}</ref>

The oysters on the walls will create {{Convert|13000|ft}} of natural breakwaters {{Convert|1/4|mi|spell=in}} off the shore of Tottenville as part of a risk-management effort against climate change, in light of an expected rise in both storm frequency and sea levels. The oysters are intended to naturally filter the water, making it more attractive to marine life and thus restoring biodiversity. The construction of the project is an opportunity for local classrooms and the community to get involved and see marine biology in action.<ref name="City Lab" /> The Living Breakwaters citizens advisory committee was established in 2015 and looks to gather opinions of the locals on decisions through the project.<ref>{{cite web |title= Living Breakwaters Citizens Advisory Committee (CAC) &#124; Governor's Office of Storm Recovery (GOSR)|url=https://stormrecovery.ny.gov/LBWCAC |website=The Official Website of New York State |accessdate=2019-11-20}}</ref> Project construction was originally planned to start in late 2019,<ref name="Wattles" /> but ultimately began in 2021.<ref>{{Cite web|date=13 September 2021 |title=Governor Hochul Announces Start of Construction on $107 Million Living Breakwaters Project Off-shore of Staten Island |url=https://www.governor.ny.gov/news/governor-hochul-announces-start-construction-107-million-living-breakwaters-project-shore |access-date=2024-01-01 |website=www.governor.ny.gov |language=en}}</ref><ref name="Rebuild by Design" />
