The Wrack

Since her arrival at the Wells Reserve at Laudholm in 2008, research scientist Dr. Jennifer Dijkstra has followed two main lines of inquiry. In addition to investigating seaweed, crab, and snail interactions in the salt marsh, she has also looked into how climate change may affect mercury accumulation in coastal food webs.

When Jenn started her post-doctoral fellowship, research director Michele Dionne asked her to work on mercury. "It was a little daunting," Jenn admits. "I had never worked on contaminants, and mercury is not a straightforward contaminant."

On a classic October morning, a research team heads to the EliotSouth Berwick line, where a private landowner has opened his property for a Wells Reserve study of fish and fish habitat. Parking the pickup at the end of a long hayfield, the five gather up gear and step into a middle-aged pine-oak forest, then head downslope past ferns and toppled trees till the trail goes wet underfoot, the canopy breaks, and they stand at the edge of Shoreys Brook. This is headquarters for the next few hours. It is one of eight sites along the brooks 4.3 miles being surveyed for resident and migratory fish, and their habitat, in advance of a planned dam removal downstream.

With a camera and a computer you have everything you need to monitor habitat change over time at the Wells Reserve.

Rainwater harvesting can reduce flooding and erosion issues, as well as surface-water contamination, by slowing down and decreasing the volume of stormwater runoff. One way to harvest rainwater is by using a catchment technique such as rain barrels.

Flooding in York County  is it becoming more common? Roads impassable, bridges washed out, basements full... the stories have become all too familiar in recent years.

The Mother's Day storm in May 2006 seemed an anomaly till the Patriots' Day storm hit in 2007. This March, the Wells Reserve measured 16 inches of rainfall, 5 inches more than Portland's record-setting 11. The roads closed and the sump pumps hummed again.

The Wells Reserve has produced or assisted with every key conservation planning document prepared for southern Maine watersheds over the past decade. The most recent issue of the Watermark newsletter includes a chart to show which plans cover each town and watershed. You can download the watershed conservation chart below (it's a small PDF).
