February 10, 2026 — On a still April morning, one of the most important things happening on Cape Cod is easy to miss unless you’re really looking. No crowds. No signs. Just narrow ribbons of water where silver flashes push upstream, muscle and instinct carrying river herring from the saltwater back to the ponds and wetlands where their lives began.
For decades, those fleeting migrations have told a quiet story about the health of the Cape’s ecosystem. Now, local researchers and conservationists say the story needs more listeners.
The Association to Preserve Cape Cod is recruiting volunteers for the 2026 river herring count season, a citizen science effort that relies on something everyone knows how to do: count. All it requires is people willing to show up consistently, watch carefully, and write down what they see.
The commitment is not a heavy lift, but the payoff is anything but lightweight.
“Ten minutes at a run, a few times a week, adds up to information we can use to track the run, spot problems, and see whether restoration work is paying off,” said Mike Palmer, an ecologist at the APCC who coordinates volunteer monitoring across the region.
