Alewife Migration Walk

Mill Brook Preserve (map)

Join the Gulf of Maine Research Institute (GMRI) and Presumpscot Regional Land Trust on a walk during the annual alewife migration season at Mill Brook Preserve in Westbrook. The walk will be about 2 miles round-trip on uneven, hilly terrain. During the walk, we’ll discuss the significance of the alewife to our ecosystem and the challenges they face during their spawning run. We’ll also learn about the methods scientists use to collect data on these fish and how the data help us gain a better understanding of the pace and direction of the changes taking place in the coastal marine fishery ecosystems that support our region. Our scientists will guide us through the process of observing and collecting data on these fascinating fish and we’ll learn how the data help us better understand how environmental changes impact alewife and the ecosystems they support.

There will be two walks being offered this year at Mill Brook Preserve:

• Wednesday, May 27th, 10:00 AM - 12:00 PM
• Thursday, June 4th, 3:00 PM - 5:00 PM

All are welcome to register and learn about the alewife and the important role they play in our environment. Parking is limited and arrival information will be shared with registered participants.
