Stream Smart

Stream Smart works with contractors, landowners, and other professionals responsible for road-stream crossings to construct culverts that maintain fish and wildlife habitat while protecting roads and public safety.

In 2011, Maine Audubon and partners launched Stream Smart. Since the start of the project, we have hosted workshops and field trainings for over 1,000 people across the state, reconnecting hundreds of miles of stream habitat for wildlife. Stream Smart road crossings let the stream act like a stream and make the road invisible to the stream.

Why are streams important?

Streams are important habitat for fish and other wildlife. Eighty-five percent of wildlife species either live in or use riparian (water-related) habitats throughout the year to breed, travel, and find food and water.

In Maine, brook trout, Atlantic salmon, river otters, and other wildlife get “stuck” at decaying, undersized stream culverts. One of the least visible elements of our built infrastructure, stream culverts allow roads to cross Maine’s vast network of streams. Surveys show that up to 90 percent of Maine culvert crossings make movement difficult or impossible for wildlife at least part of the year. When wildlife habitat is fragmented like this, it can result in population declines and the loss of species.

Why are Stream Smart crossings a wise investment?

Stream Smart road crossings last longer than traditional culverts and reduce maintenance costs, saving money in the long term. Stream Smart crossings can typically withstand flooding and can better weather the increasingly intense storms we are experiencing without damaging the road.
