Portsmouth, NH – For those of us who live, work, and play in the coastal watershed, it can be hard to take a step back and get a big-picture view of how things are going in our estuaries and the communities around the watershed. Fortunately, our friends at the Piscataqua Region Estuaries Partnership (PREP) took on this gargantuan task to help us do this, with their recent release of the 2018 State of Our Estuaries report. Every five years, PREP, as one of the 28 National Estuary Programs around the nation, synthesizes data and reports out on the status and trends of the health of our estuaries – both the Great Bay Estuary and the Hampton-Seabrook Estuary. On December 8th, 173 people came together at the State of Our Estuaries (SOOE) conference in Portsmouth to learn about the results of this recent assessment.

This incredible video (directed and edited by Emily Lord) kicked off the conference, with footage exploring the Piscataqua Region watershed from the headwaters to the coast, reminding us all of what we are working to protect.

 

Next on the agenda was the keynote address by Peter Egelston, owner and president of Smuttynose Brewing Company. Peter talked about how his relationship with water has changed with time and geography – from living in southern California, where water quantity is a real concern, to living in NYC near a superfund site, to now owning a brewing company highly dependent on water (beer is 95% water). He emphasized that we need to find regional solutions to regional problems and translate the State of Our Estuaries report into action.

Then, a series of presenters and panelists summarized what we know about the health of our estuaries and the trends in a range of indicators. To cut to the chase, there was a lot of bad news – 12 of the 16 environmental indicators are in the ‘cautionary’ or ‘negative’ trends categories. These indicators provide signals that tell us about the health of the estuaries, and the bottom line is that our estuaries have declined and are under stress. Eelgrass, oysters, and clams have declined. Invasive seaweeds have increased. These are signs of the estuary responding to stresses, which can come from natural processes and human impacts.

Climate change impacts can be found throughout the report. The changing climate adds stresses to the system and can worsen existing stressors. For example, many of the water quality parameters are influenced by precipitation patterns – “Between 1996 and 2014, extreme precipitation (two inches or more in one day) in the Northeast was 53% higher than it was in the previous 94 years” (2018 SOOE report, p.7). This is a stressor on its own and also exacerbates the impacts of rising impervious surface rates due to growing population and development. There is a LOT of work to do, and the task feels daunting. Estuaries are complex in their functioning and their response to stress, and there are some factors we cannot control, so we need to identify the leverage points we can impact and focus on where we can make the most progress.

BUT it wasn’t all bad, and there are some awesome positive elements to report:

4 environmental indicators are showing a positive status or trend:

  • Nutrient loading from point sources: Total nitrogen loading in the Great Bay Estuary from 2012-16 was 26% lower than 2009-2011 levels, primarily due to low rainfall and significant reductions in nitrogen loading coming from municipal wastewater treatment facilities. Several municipalities in the watershed are making improvements in their wastewater treatment, and we’re already starting to see progress in this indicator!
  • Beach advisories: Beach advisory days occurred less than 1% of beach days from 2012 to 2016.
  • Toxic contaminants: Most concentrations of measured metals and organic chemicals in blue mussel tissue are declining or not changing (though many emerging contaminants are not yet monitored consistently).
  • Bacteria: Dry weather concentrations of bacterial indicators of fecal pollution in the Great Bay Estuary have declined substantially (67-93%) at four monitoring stations between 1989 and 2016.

2 of the 4 ‘response’ indicators (measuring progress toward management goals) show positive trends:

  • Conservation lands: 15.5% of the total land area in the Piscataqua Region has been conserved – an increase of 5% since 2011.
  • Migratory fish restoration: As of 2016, 42% of the historical distribution for river herring in the Piscataqua Region’s rivers has been restored (getting closer to PREP’s goal of restoring 50% of historical distribution by 2020!).

There are 3 new social indicators, measuring the social landscape that could impact environmental indicators:

While there isn’t enough information yet to measure these trends, we now have a baseline to be able to gauge progress over time! These new indicators are housing permit approvals, stormwater management effort, and stewardship behavior.

  • Stormwater management effort: As of July 2017, 8 of the 42 NH municipalities in the Piscataqua Region watershed had adopted the model stormwater standards, 7 were in the process of adoption, and 5 had a partial or different set of stormwater standards. Zero communities have adopted a stormwater utility, but we have 5 years to make progress on this indicator for the next State of Our Estuaries report!
  • Stewardship behavior: In 2016, almost 40,000 volunteer hours were logged in the watershed (through the work of six NH-based stewardship groups).

The best part of the day (in my opinion) was hearing about the steps municipalities and community members are taking to improve water quality and protect our estuaries. We heard about wastewater treatment plant upgrades and a dam removal project in Exeter, an assessment of the vulnerability of Portsmouth’s historic district to climate change, water quality projects in Kittery, stewardship projects led by the Great Bay Gunners, and collaborative work between communities through the Seabrook-Hamptons Estuary Alliance. Despite the predominantly negative news reflected by the monitoring results, what gives me hope is hearing about the dedication and on-the-ground efforts by so many individuals and communities to make progress.

It will take a village to improve and protect the health of our estuaries, especially as stressors from climate change continue to grow – from those out in waders collecting data, breweries using locally farmed kelp to make creative (and tasty!) beers, and local restaurants supporting the local oyster restoration work, to those in the lab testing water samples or on the computer crunching millions of data points to identify trends, municipal decision makers and citizens supporting wastewater treatment plant upgrades, improved stormwater regulations, and buffer protection, to the land trusts and landowners working on conserving more land, citizen scientists providing boots-on-the-ground monitoring and research capacity, and folks like the Great Bay Gunners and so many others volunteering their time to clean up the places they care about. Though we left the conference with a copy of the report that contains some disheartening news, I think we all also left feeling reenergized and optimistic about the hard-working and passionate community that already exists around caring for our estuaries!

Following the conference was an amazing event at 3S Artspace in Portsmouth called “Stories from the Field: Celebrating Citizen Science in New Hampshire,” hosted by PREP, NH Sea Grant, UNH Cooperative Extension, and the Gundalow Company. Five citizen science volunteers told TED-style stories about why they volunteer and what the experience has meant for them. Over 140 attended the event, and you could hear a pin drop during the volunteers’ stories! From growing oysters to serving as a “salamander crossing guard” and more, these volunteers are doing great work to take care of New Hampshire’s natural resources. And we know from the 2018 State of Our Estuaries report how needed this work is. Hopefully, the 2023 State of Our Estuaries report will show an increase in the “stewardship behavior” social indicator as well as progress in more of the environmental indicators.
