River herring are a crucial link in the coastal food chain. During the spring and summer, many fish and wildlife species eat herring as the herring migrate to their spawning areas. In the ocean, herring also fill an important niche.

River herring are also keystone species; that is, species whose health and well-being reflects the overall state of the coastal ecosystem. They reflect watershed problems, such as man-made alteration of the natural hydrology, and water pollution.

The Association to Preserve Cape Cod has been monitoring herring runs across Cape Cod since 2009.
