Data released Friday shows that a crucial piece of the ecosystem of the Great Bay estuary continued a seventeen-year downward trend.
Eel-grass is a big deal to the Great Bay. According to Rachel Rouillard, the executive director of the Piscataqua Region Estuaries Partnership (PREP), “eelgrass is like our canary in the coal-mine, it’s a fundamental underpinning of the health and vitality of the whole system.”
Grass doesn't get a lot of appreciation aside from lawns and hayfields, but grasses play an essential role in ecosystem health. When soil is disturbed by hurricane, fire or logging, grasses take quick advantage of. Dormant seeds awaiting the right conditions sprout and up come the grasses.
Several seacoast communities have been ordered to upgrade their waste-water treatment plants by the EPA.But towns are pushing back on the question of how much the plants need to improve.
Durham is in that boat. The town is trying a new approach to pollution control called adaptive management. And depending on how things go for Durham, this could be the way the way towns and the EPA will resolve difficult and expensive water problems going forward.
