Soil and Water Conservation districts are local units of government that develop, manage, and direct natural resource programs at the community level. The Nassau County Soil and Water Conservation District has existed since 1977 and has provided county residents with assistance, educational programs, and services for over 45 years.
Please explore our website and consider becoming an active member of your District.

Education
We seek to educate municipalities and residents of all ages about best practices for natural resource conservation. We do this through a variety of means, including distributing educational materials, participating in community outreach events, hosting conferences, plant sales, training events, and workshops, and organizing the annual Long Island Regional Envirothon, which draws hundreds of high school students each year.
The NCSWCD regularly offers the NYSDEC-endorsed 4-hour Erosion & Sediment Control Training for contractors and municipal employees.
The Long Island Regional Envirothon
The Envirothon® is an environmental and natural resource conservation problem-solving, teambuilding, and leadership experience and competition for high school students (grades 9-12 or ages 14-19) across the United States, Canada, and China. Incorporating STEM (Science, Technology, Engineering, and Math) principles, experiential learning, and hands-on outdoor field experiences, the Envirothon fosters student learning in the five subject areas of: Aquatics, Forestry, Soils, Wildlife, and a Current Environmental Issue, which changes annually.
Native and Invasive Species Education
Nassau County SWCD provides Educational Programs on Native and Invasive Species to residents of Nassau County, Gardening clubs, Libraries, and other local educational entities.
Pictured here is the SWCD staff on the way to install a Bat Box in Pond Park. Once established, this will provide a vital habitat for our Long Island native Little Brown Bats (Myotis lucifugus). Native bat species help control populations of mosquitoes, beetles, and other pests, A single little brown bat can catch 600 mosquitoes in just one hour. Bats also play essential roles in native plant pollination and the dispersal of seeds.
Trail Maintenance at Muttontown Preserve
Nassau County is home to countless preserves that serve as habitat and refuge for the native plants and wildlife that represent Long Island’s unique ecology. These preserves act as gateways for local communities by allowing access to untouched natural environments, and many organizations utilize preserves to host educational trail walks and promote environmental values and stewardship.
The Nassau County Soil & Water Conservation District has been working to establish a system of trails in this ecologically unique county preserve.
Rain Garden Revitalization
Rain Gardens are essential in recharging underground aquifers, of which many Long Island residents use for water. A Rain Garden is designed to capture stormwater runoff and filter it as it enters the ground. It is imperative to clean this "first flush" as it carries the greatest amount of pollutants.
Raingardens are designed to improve the quality of the stormwater before it enters the groundwater or surface waters. A rain garden can be designed and constructed in various ways to suit best the needs of the surrounding area, local aesthetics, or for educational purposes.
The Conservation District has designed and installed numerous rain gardens across Nassau County through many partnerships and grant programs, with plans to continue maintaining them.
Town of North Hempstead - Native Plant Rebate Program
The NCSWCD provided funding to reimburse Town of North Hempstead Residents who purchased native plants to create native plant gardens and rain gardens. Native plants provide food, shelter, and nesting resources for birds, pollinators, small mammals, and a variety of wildlife species.
Native plants have a multitude of environmental benefits, like extensive root systems that absorb polluted stormwater, sequestering carbon, lower maintenance requirements, and less need for fertilizer, mowing, and irrigation.
Providing rebates for the installation of these plants would lead to more native plants being put into the ground, which will support the Town's effort to increase native plants and wildlife habitat throughout the Town of North Hempstead.
A Day in the Life of a South Shore Estuary Reserve
A Day in the Life is a program organized by the South Shore Estuary Reserve focused on environmental education, community engagement, and water-quality monitoring. Students will get the opportunity to collect water quality samples, learn about ecosystem services, and engage with local flora & fauna.
After the field trip event, the data collected by student groups is processed and shared for analysis, an activity in which students are encouraged to participate. This can range from tracking water & soil health throughout Nassau County to GIS analysis of the collected data.
Spotted Lanternfly
This invasive tree-hopping insect causes damage by feeding on the sugars of plants, with the potential to destroy crops and damage forests. The Spotted Lanternfly poses a significant threat to NYS and most of the United States. Learn more about what you can do to prevent Spotted Lanternfly by clicking the button below.
