When ‘citizen scientists’ help gather data, they don’t get paid, but the rewards are priceless There’s something innately restorative to the human spirit about watching the flow of water in a stream, and this is especially true in spring. The frozen landscapes and frigid temperatures of the winter months can cast a stillness across one’s interior terrain as well, so to watch the current of a river in May is surely to come alive again. That sense of renewal is even greater, though, when it extends from one’s own spirit to the larger environment. Which is just what happens when I go to watch for the herring in the annual spring monitoring program. Herring spend most of their life at sea, returning to the freshwater rivers and streams they were born in once a year to spawn. In recent times, however, their numbers have declined dramatically, possibly because of overfishing, diminished water quality and/or habitat loss. Or maybe something else entirely. Fishermen, researchers and environmentalists would all like to understand what’s causing this. To this end, volunteers help scientists monitor the herring’s arrival into the tributaries of the Hudson River and collect baseline data about these changing migration patterns. And while we citizen scientists know we’re helping out, what we get in return is worth far more than the time we give. The Call of the Wild This is not difficult work. It requires only that one stand at a bridge or the edge of a waterway for 15 minutes twice a week in April and May, look for signs of the herring, then write down what is seen — whether herring are there or not. This is about absence or presence. And if those minutes spent watching the...
