We are delighted to share that in January 2018, the City of Portland passed one of the strongest ordinances in the state to restrict pesticide use.
Executive Director Cathy Ramsdell served for nearly a year on a task force to help the city develop the ordinance. She often found herself a fulcrum of the group, reminding everyone of their common purpose to protect Casco Bay. The ordinance is similar to one that South Portland passed in 2016, also thanks in part to Friends of Casco Bay’s advocacy. While state and federalauthoritieshave been slow to protect our waters from these toxic chemicals, we are heartened to see local communities take action.
Why restricting pesticide use is important for the health of the Bay: We have long been concerned about the possible impacts of lawn chemicals—pesticides and fertilizers—on the environmental health of Casco Bay. Our monitoring efforts revealed that the lawn chemicals we are putting on yards can end up in the Bay. Between 2001 and 2009, we collected rain water flowing into the Bay and analyzed the samples for a suite of pesticides. Lab results identified 9 different pesticides in 14 locations all around the Bay. Pesticides do not belong in the Bay, as they have the potential to harm lobsters, fish, and vital habitat.
We see water itself as fundamental habitat. When water quality deteriorates, eelgrass, plankton, clams, and other marine creatures suffer. Thanks to our 25-year data set on water quality in Casco Bay, we now have a better overall understanding of the health of the Bay. We understand when and which areas of the Bay are likely to exhibit challenged water quality conditions.
Armed with this baseline data, we can now begin to address the question How is the Bay changing?—thus, the establishment last year of our first automated Continuous Monitoring Station. We will also continue to monitor selected sites at the surface, to supplement the historical data set compiled by our Citizen Stewards Program. And, we will look more intensively, using surface-to-bottom transects, at those regions of the Bay which present challenged conditions. New data and observations may help us begin to understand how climate change, excess nitrogen, and the changing chemistry of Casco Bay may be impacting the ocean food web.
Our Nabbing Nitrogen event in 2016 signaled to us that there is a huge reservoir of goodwill from people who want to help protect the health of the Bay and are willing to do that in short bursts of data collection efforts. We foresee new volunteer opportunities in this type of data collection, as well as in expanding other community service projects, such as coastal clean-ups, storm drain stenciling efforts, and issue-education events to inspire Champions for the Bay.
Citizen Steward volunteers will continue to be key to our organization as they help us move into this next phase of work to improve and protect the environmental health of Casco Bay. Casco Bay belongs to all of us, and this Bay is fortunate to have so many Friends.
