The Wrack

Bridges and culverts located along coastal roads are increasingly vulnerable to sea level rise and coastal flooding. Two interns collected data on vulnerable crossing structures to help ensure the sustainability of coastal habitat and communities.

When green crabs arrived in New England more than 150 years ago, they found an unoccupied ecological niche in Maines salt marshes. Despite their long occupancy, great abundance, and serious impacts, there is a lot left to learn about green crabs. The reserves latest research has focused on understanding seasonal movements, population structure, sexual maturity, and effects on habitats.

The salt marsh tiger beetle, a species of special concern in Maine, appears to have a stable and secure population at the Wells Reserve in 2019.

It sounds cool: Blue carbon. Have you heard of it? What does it make you think?

Three hundred and fifty million years ago, the supercontinent Pangaea floated where you sit today. It was a warm, wet world, bathed in oxygen and soupy seas. The Carboniferous period was a time from which we get a lot of the fossil fuels we now use to power our society.

The invasive European green crab is not only a popular topic in the media these days; here at the reserve green crabs are receiving their?fair share of attention as well? 5,878 of them so far to be exact!

The Wells Reserve has teamed up with the University of Maine, Casco Bay Estuary Partnership, and Southern Maine Health Care to study the impacts of the invasive European green crab (Carcinus maenas) on the geology and stability of our marshes. Over the summer we have been collecting abundance data that will later be used in conjunction with fyke net data, water quality data, and even geological techniques to better understand the effects green crabs are having on salt marshes throughout southern Maine.

Create a U.S./Canada working group, identify research gaps, and establish a regional approach to blue carbon science and policy.

Jennifer Dijkstra was always going to be a scientist. As a child summering on Grand Manan, she clambered over the islands rocky shoreline grabbing fistfuls of seaweed and peering into shallow waters to spy on crabs and snails. This summer shes been doing the same thing, but with three degrees of separation (BS, MS, and PhD), she now calls her objects of interest Ascophyllum, Carcinus, and Littorina.

For many budding biologists, the journey from tide pool playground to salt marsh research transect stops short. For Dr. Dijkstra, research scientist at the Wells Reserve, the dream came true.

It is probably a rare coastal beachfront property owner who is not aware that beaches are dynamic systems that erode and accrete in response to storms, sediment supply, rising sea level, and the proximity of sea walls, jetties, and other forms of coastal "armor." Many beachfront owners are also aware that "natural" barrier beaches and their dune systems are able to persist in the face of sea level rise by transgressing, or migrating shoreward.
