While a lush and dense forest has grown up in the two outer basins of the Ridgewood Reservoir, a freshwater pond that attracts waterfowl occupies the middle basin. This fresh water source is critical to migrating birds on the Atlantic Flyway. Courtesy Steve Nanz

Nature

The Reservoir provides crucial ecosystem services to the surrounding neighborhoods. It improves air quality by filtering out particulates and harmful chemicals, mitigates heatsink effects of concrete and asphalt in summer months, absorbs storm water and prevents it from flooding the neighborhoods below, and mitigates combined sewage overflows.

The Reservoir is also a perfect case study of ecological succession. With the introduction of new upstate reservoirs in the 1950s, Ridgewood Reservoir became obsolete and was decommissioned in the 1980s. A lush and dense forest has grown in its two outer basins while the middle basin has a freshwater pond used by waterfowl. The Reservoir is home to more than 160 species of birds, many of whom migrate on the Atlantic Flyway, including some that are threatened or endangered. As restoration work continues, and the public has more access to its open spaces, Ridgewood Reservoir will increasingly be recognized as one of New York City’s ecological and cultural treasures.
