Maine’s Underwater Seaweed Forest: Rockweed! – Field Trip

with Dr. Robin Hadlock Seeley, Ph.D.

$10

Location: Reversing Falls Park, Mahar Point (DIRECTIONS link)

In today’s session, we will meet with Dr. Robin Hadlock Seeley at Pembroke’s Reversing Falls Town Park, where we will walk on the shore at low tide and walk through the low tide rockweed “forest”, learning about the species that live within its branches and canopy, its growth and growth forms, and ways the forest is affected by different harvest methods in Maine. This session will further explain why and how the Rockweed is so important to the ecological well-being of Maine’s marine commercial fisheries and wildlife. It starts in the western parking area near the historic Mahar cemetery.  You will see some of the different species covered in the lecture session, as well as seals playing in the Falls just off the shore. This session involves a very short walk from a nearby parking lot 100 feet from the shore. The walking 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. After the session ends, participants will have the option to have a morning snack or breakfast on picnic tables and explore for themselves the adjacent shoreline trails (moderate hiking difficulty: trails are not level or smooth) of the Downeast Coastal Conservancy’s Reversing Falls Preserve, where Dr. Seeley serves as a volunteer steward. This field trip is limited to 15 people. Water appropriate, sturdy foot wear and all participants must sign a liability wavier that day. 

It is not necessary for you to have taken Dr. Seeley’s Sept. 9th lecture class on Rockweed to participate in this walk; however, places are limited and those who signed up for the lecture class will have first priority for the field trip.  For those students who are taking the Sept. 9 class, please answer “Yes” at checkout when you are asked if you are taking the class and this field trip will be reduced by $5.00.

Trailhead Directions: Take Route 1 to West Pembroke. Turn south onto the extension of Route 214 next to the Pembroke Post Office. Turn right at the next stop sign and then an immediate left up a very small hill onto the Leighton Point Road (also called Leighton Neck Road). Continue 3.3 miles; then turn right onto Clarkside or Cemetery Road for 1.2 miles. At the end of Clarkside Road (you will see the Bay!), turn left onto Reversing Falls Road (not marked by a street sign). Go 1.5 miles to the Town of Pembroke Reversing Falls Park, and when you arrive, bear right and go down the hill towards the water and a parking area.
