35 Volunteers Help Kickoff Campaign with Beach Cleanup

Volunteers from the beach cleanup day in New HavenNew Haven – One hundred pounds of litter – everything from deflated Mylar balloons and monofilament fishing line to plastic bottles, Styrofoam cups, straws, cigarette butts and lots of bottle caps — filled the buckets and reusable bags of 35 volunteers Thursday at Lighthouse Point Park as they helped launch a campaign to keep plastic trash out of Long Island Sound.

“My husband and I grew up down here, so we just wanted to come and help out,” said Lisa Ratti, who came with her husband Salvatore and their daughters Kylie, 13, Courtney, 11, and Rosalie, 4, from their home in Newington to work with the other volunteers in picking up trash.

The two-hour cleanup on a bright, windy August day at the popular city beach and picnic area was the start of this year’s “Don’t Trash Long Island Sound – Break the Single-Use Plastic Habit” campaign sponsored by the Long Island Sound Study, Connecticut Sea Grant and Mystic Aquarium. Now in its third year, the campaign this year expanded with four groups joining in the kick-off event – The Connecticut Fund for the Environment/Save the Sound; Audubon Connecticut; The Nature Conservancy’s Connecticut chapter; and SoundWaters, which sponsored cleanups at the same time at two Stamford parks.

Conservation Planning

aerial view of Connecticut River and agricultural fieldsExcess fertilizer use and inefficient nutrient management strategies often are causes of water quality impairment in the United States. When excess nitrogen enters large water bodies it enhances algae growth and when that algae decomposes, hypoxic conditions—often called a “dead zone” occur.

Nutrients carried to the Long Island Sound have been linked to the seasonal hypoxic conditions in the Sound. There are many different sources of nutrients within the Long Island Sound Watershed, an area encompassing parts of Connecticut, Massachusetts, New Hampshire, New York, Rhode Island, and Vermont. These sources include municipalities, industry, agriculture, forests, residential lawns and septic systems.

The Long Island Sound Watershed Regional Conservation Partnership Program (LISW-RCPP) is a technical and financial assistance program that enables agricultural producers and forest landowners to install and maintain conservation practices. The goal of this program is to enhance natural resources and improve water quality. Funded by the U.S. Department of Agriculture’s Natural Resources Conservation Service (NRCS), the LISW-RCPP supports efforts that find common ground among agricultural producers and conservation organizations in working towards the sustainable use of soil, water, and other natural resources.

Conservation practices can achieve multiple positive environmental outcomes, including water quality improvement. A widemap imagery for conservation planning for farms variety of practices exist including in-field (cover crops, reduced tillage, diversified rotation and nutrient management), and edge-of-field strategies (grassed water ways, buffer strips, riparian area, bioreactors and wetlands). These changes, in turn improves nitrogen retention during vulnerable leaching periods in the spring and fall. Conservation strategies also function to safeguard other ecosystem roles, such as carbon sequestration, animal refuge habitat, fisheries and recreation.

Prioritizing areas for nutrient management strategies requires an understanding of the spatial relationships between land use and impaired surface waterbodies. Our project utilizes a geographic information systems (GIS) based approach to under- stand and act upon these important spatial relationships. In part, we are identifying contemporary and historical hotspots of agricultural land use by using satellite- derived land use land cover (LULC) classifications initially developed by
the University of Connecticut’s Center for Land Use Education and Research (CLEAR). Spatial analyses depicting the proximity of agriculture to highly valued water resources (both surface and ground- water) serves as the foundational work that informs where efforts to protect and restore water quality will be most impactful to the greater Long Island Sound Watershed.

Our future work will pair spatial maps with modeled contemporary and historical nutrient loading patterns to expand regions of interest. Our goal is to provide education and tools that help farmers realize the benefits of sustainable agriculture with individual conservation plans tailored to their specific needs and objectives. Connecticut’s environment of diverse crops and farms offers unique opportunities and challenges. UConn Extension is offering soil tests and interpretations to assess each farm’s nutrient needs. We look forward to co-creating knowledge with farmers and developing soil health solutions for long-term production goals and resilient farms.

STEM Education for Teens, Adults, and Teachers

nrca students in waterThe Natural Resources Conservation Academy (NRCA) is a group of three linked projects that focus on connecting STEM education for high school students with natural resource conservation at the local level. With over 130 land trusts in the state and each of its 169 municipalities having a Conservation Commission, Connecticut has a long history of local conservation. NRCA provides an assist to these efforts, while educating students and teachers about the science and issues surrounding natural resource protection. The TPL is joined by the foundational NRCA project, the Conservation Ambassador Program (CAP), and the Conservation Training Partnership (CTP). CAP brings high school students from around the state to campus for a week-long intensive field experience at the UConn main campus, from which they return home to partner with a community organization on a conservation project of their own design. CTP moves around the state for two-day training of adult-student teams that teaches them about smart phone mapping applications and their use in conservation. The teams then return and implement a conservation project. Together the three programs have educated 308 participants and resulted in 187 local conservation projects in 105 towns, involving 119 community partner organizations.

Teacher Professional Learning: Professional Development Workshop

teachers during a workshopUConn Extension is leading a project that provides high school science teachers from across the state with a head start on a new way of teaching. Over the past two summers, 48 teachers from 38 school districts attended the 3-day Teacher Professional Learning (TPL) workshop, Land and Water.

The training, funded by a USDA/NIFA grant, was developed and is taught by Extension faculty from the Center for Land Use Education and Research (CLEAR) and partners from the Department of Natural Resources and the Environment, the Center for Environmental Sciences and Engineering, and the Neag School of Education. This formidable partnership conducts three inter-related STEM projects collectively known as the Natural Resources Conservation Academy.

Connecticut is one of 19 states to date that have adopted the Next Generation Science Standards (NGSS), an ambitious new way of teaching science that was developed by  a consortium of states and nonprofit science organizations including the National Science Teachers Association, the American Association for the Advancement of Science, and the National Research Council. Connecticut school districts are still in the very early stages of adopting NGSS method- ologies, and many teachers are eager for educational units and techniques that fit NGSS standards.

The main focus of the UConn workshop is the relationship of land use to water resource health, and the use of online mapping and other geospatial tools to help explore these relationships—particular strengths of the CLEAR team. The UConn campus and surrounding area provide an ideal outdoor laboratory to explore these concepts. Attendees sample three streams within about a mile of campus, all with very different characteristics based on the predominant land use of their respective watersheds—agriculture, urban, and forest. They then come back to the classroom, study their results, and compare notes to get a sense of the importance of land use in determining the health of a water body. Also used in the instruction is the campus itself, which has become a showcase of low impact development (LID) practices designed to reduce the impact of stormwater runoff on local streams. After learning about LID and touring the green roofs, rain gardens, and pervious pavements across campus, the participants visit a nearby campus build- ing and devise their own plan for LID installation. The workshop also introduces them to online mapping and watershed analysis tools that enable them to focus in on their own town, watershed or even high school campus, thus using their community waterways as a teaching tool.

Teachers leave the training with a wide variety of resources to help them in the classroom, not the least of which is their personal experience working through these topics with the Extension instructional team. In addition, the Neag members of the team have developed a 25-unit lesson plan that follows the educational progression of the workshop; teachers are encouraged to adapt all or part of the lesson plan for their use. Of the latest (summer 2018) class of 25 teachers, 100% said that the training was relevant to their classroom instruction, that the training was time well-invested, and that they would recommend the training to other teachers. Research is ongoing on how many teachers implemented all or part of the curriculum, and how it played out with their students. Although the project plan was for two workshops, they have been so well received that the team is holding a third TPL training in the summer of 2019 and is looking for resources that would enable them to continue this program for the foreseeable future.

What do taking a trip to the beach, testing a well, and planting a new garden have in common? You guessed it—water. UConn is home to a state-wide organization focused on providing Connecticut’s citizens with information and research about all the water resources we encounter in our daily lives.

As the state’s land grant university, UConn’s College of Agriculture Health and Natural Resources became the home of the Connecticut Institute of Water Resources (CTIWR) in 1964, and it is housed in the Department of Natural Resources and the Environment. The institute seeks to resolve state and regional water related problems and provide a strong connection between water resource managers and the academic community. CTIWR also shares water-related research and other information with the general public to bridge the gap between scientists and the community.

The institute is currently expanding and focusing more attention on community outreach with the arrival of new center director, Michael Dietz.

“Our goal is to increase visibility of the water research in language that the general public can understand and use in their daily lives,” says Dietz. “We want to become a one-stop shop for information about all kinds of water-related issues. Where can you go to get your water tested, up to date information about drought or water quality around the state, in addition to research reports and funding opportunities for scientists.”

Recent projects explored leaching of nitrogen and phosphorous from lawns, relationships between metals and organic matter in soils, and quantifying the impact of road salts on wetlands in Eastern Connecticut.

“UConn has some really talented water researchers from different disciplines who can help citizens in our state better understand issues that affect our water resources. Through CTIWR, we’ll make sure that these experts and citizens can come together, speak the same language, and learn from one another.”

Reducing Winter Road Salt Use

snow plow on a street in Connecticut during winter stormExtension educator Mike Dietz focuses on protecting surface waters with green infrastructure techniques in his research and Extension work. Mike has been involved in the development of the Green Snow Pro program, and he is the Director of the Connecticut Institute of Water Resources.

The scientific studies continue to pile up, and confirm the same thing: road salt is causing lots of problems in our streams and groundwater. The majority of salt applied is sodium chloride, also known as rock salt. In the absence of a new “miracle” deicer, salt will continue to be the most cost effective product for the foreseeable future. Therefore, the only way to reduce the impacts will be to reduce the amount that gets applied, while still keeping surfaces safe for travel.

New Hampshire began the “Green Snow Pro” voluntary salt applicator certification program to train municipal public works employees and private con- tractors. This training includes information about the science of salt, the downstream impacts of salt, how to properly apply given weather conditions, and how to calibrate equipment. An additional key component of the New Hampshire program is limited liability release: a property owner who hires a Green Snow Pro certified contracted has liability protection from slip and fall litigation.

Given the success of the program in New Hampshire, the Technology Transfer (T2) Center at UConn gathered professionals from UConn Extension, Connecticut Department of Transportation, Connecticut Department of Public Health, municipal public works, and Connecticut Department of Energy and Environmental Protection to adapt the program here in Connecticut. A pilot of the training was per- formed here at UConn in November 2017. UConn public works staff received a classroom and spreader calibration training. Mike Dietz maintains a monitoring station on Eagleville Brook downstream of campus. He was able to compare the amount of salt in runoff for the winter after the training, as compared to prior years (correcting for the number of storms). Substantial reductions were found: over 2,600 less tons of salt were used during the 2017- 2018 season, corrected for the number of storms. This resulted in a savings of over $313,000 in salt costs alone! A summary of these findings is currently under review at the Journal of Extension.

The statewide implementation of the Green Snow Pro program in Connecticut has begun: during the fall of 2018 the T2 center gave two separate trainings for municipal public works crews and more are being scheduled for this year. The group will continue to meet to work on the liability protection here in Connecticut, as well as expanding the offering to private contractors.

This effort has been a great collaboration of UConn educators, regulators, and public works professionals. The success of this program highlights the fact that education truly can have lasting environmental benefits.

The tidal marsh migration buffer at Dodge Paddock Beal Preserve in Stonington was planted on Friday May 3, 2019. With a stalwart group of dedicated volunteers, over 100 native plants were put in. This area borders a coastal wetland and the plants need to be able to withstand occasional salt spray as well as possible inundation during extreme storm events. This part of the preserve, owned by Avalonia Land Conservancy, was formally a cultivated garden. Garden plants were removed and the area was covered in black plastic last summer to kill any remaining roots and seeds. The area was seeded with native grasses in the fall of 2018 with a planned spring planting. As sea level rises, areas within the preserve are getting wetter and wetter, so native plants were carefully chosen to withstand wetland migration.
