Maine’s Underwater Seaweed Forest: Rockweed! - Lecture
with Dr. Robin Hadlock Seeley, Ph.D.
$10
The underwater seaweed (rockweed) forests of Maine support commercial fisheries and wildlife (otters, shorebirds, puffins, eider ducks, etc.). How much do you know about rockweed forests? Rockweed, Ascophyllum nodosum, is a foundational coastal species and an ecosystem engineer. Yet it is also targeted by an industry removing millions of tons of rockweed for agricultural products such as fertilizers and cow feed additives. This sets up a conflict between landowners, who own the rockweed, and the rockweed removal industry. In this classroom session with our instructor Dr. Robin Hadlock Seeley, we will get to know much more about rockweed as she discusses its value in the structure and functioning of the marine food web, including species such as scallops, lobster, cod, alewives, otters and sandpipers. Attendees will also get a good introduction to Maine law affecting rockweed and its commercial harvesting, as well as an outline of the commercial harvest controversy that surrounds it.
For those who find this session fascinating and wish to learn more, Robin is offering us a second session – an early morning field trip to Pembroke’s Reversing Falls Town Park - to see firsthand the undisturbed rockweed forest there, with “trees” over 4 feet long, at low tide. You may also see some of the different species covered in the lecture session, as well as seals playing just off the shore. This walk involves a very short walk from a nearby parking lot 100 feet from the shore. The surface is a gentle slope to the water, and we will take our time, but rockweed is slippery, and the intertidal area is not considered accessible to those with mobility concerns. This special event will occur this Thursday, Sept. 11th, and the event is limited to just 15 participants. You must sign up for this separately.
