Questions (and some answers) about the Effects of Solar Development on Wetlands @ Online webinar
Mar 3 @ 2:00 pm – 3:00 pm

Presented by: Laura Lapierre, Vermont DEC- Wetlands Program Manager

The State of Vermont is a leader in the nation for reducing their carbon footprint to mitigate climate change.  The unintended consequence of incentivizing solar development is a strong desire by developers to place solar fields within and adjacent to wetland resources.  This situation has brought up many interesting questions: Can solar avoid wetland resources and achieve energy production goals? Are posts and aerial coverage of panels all that impactful to wet-meadows? How does the annual mowing effect invasive spread? Is solar less impactful than agricultural production? Is solar competing with wetland restoration efforts? Or could solar be a form of wetland restoration?

This presentation will explore Vermont’s experience with solar development, provide management tips, and delve into Vermont’s ongoing research, monitoring, and policy development.

In 2015, NEIWPCC and ASWM co-hosted a two-part series webinar (ASWM log-in required) about solar development and wetlands.  This is a follow up presentation on the advances in Vermont solar policy with wetlands.

NH’s Progress in the Development of Biocriteria to Assess Wetland Condition @ Online webinar
Mar 17 @ 2:00 pm – 3:00 pm

Presented by: Sandy Crystall, PWS – New Hampshire Department of Environmental Services (NHDES) Wetlands Bureau

New Hampshire has been working toward the development of wetland-specific water quality standards. Sandy will review the results of the wetland monitoring and assessment work conducted over several years in coordination with Maine DEP. NHDES’s methods included sampling aquatic macroinvertebrates, water, vegetation, and applying two rapid assessments. Sandy will describe the results of the four years of sampling, as well as the related Floristic Quality Assessment work being conducted by Bill Nichols in the NH Natural Heritage Bureau.

About the speaker:

Nonpoint Source Pollution


Long Island Sound Community Based Social Marketing Workshop @ Beardsley Zoo
Apr 28 – Apr 29 all-day

Do you work with people and communities to tackle environmental challenges that impact Long Island Sound and its rivers, harbors and bays?

The Long Island Sound Study is pleased to sponsor a workshop on how to plan and implement an effective outreach campaign, incorporating scientific knowledge on behavior change to encourage local citizens to commit to and take positive actions for cleaner waters and a healthier environment.

The two-day training for environmental and municipal leaders will be led by Dr. Doug McKenzie-Mohr, a Canadian environmental psychologist. More than 75,000 program managers have attended Dr. McKenzie-Mohr’s workshops throughout North America, Europe, Australia, and New Zealand. This is his first workshop in our region.

Workshop attendees will learn the five steps of Community-Based Social Marketing: selecting behaviors, identifying barriers, developing strategies, conducting pilots, and broad scale implementation; and be exposed to numerous case studies illustrating its use.

  • Date: April 28-29, 2020
  • Location: Hanson Exploration Station, Beardsley Zoo, 1875 Noble Ave., Bridgeport, CT
  • Registration: Early Bird (through April 6): $75; Regular (April 7 or later): $95

Registration includes 2-day attendance, light breakfast, lunch, free on-site parking, and a copy of McKenzie-Mohr’s book, Fostering Sustainable Behavior.

Check the Long Island Sound Study CBSM workshop web page for further information. Registration is expected to open mid-February.


McKenzie-Mohr is a recipient of the American Psychological Association’s inaugural award for innovation in environmental psychology and the World Social Marketing conference’s inaugural award for contributions to the field of social marketing.  You can learn more about his approach at

The Long Island Sound Study is a multi-jurisdictional ecosystem-based management program that works with federal, state, and local partners to restore and protect Long Island Sound. NEIWPCC, with support from The Nature Conservancy-Connecticut and the Eastern Connecticut Conservation District, is helping to organize the workshop.
