Nassau County is a unique place to live and work. The glaciers created the topography of Long Island that we know today. The Native Americans, the island's first inhabitants, lived here for the great climate, abundant marine life, and its forests and soil for growing crops. Protecting wildlife in Nassau County is particularly important as Long Island serves as a key refuling area for many migratory birds. We help support native wildlife in many ways; creating homes for pollinators like bats, using native plants in our restorations and gardens to supply local wildlife with essential food sources. 

Native and Invasive Species Education

Long Island is home to many native bat species. Nassau County SWCD recently planted a Bat Box in Pond Park, Great Neck Estates.


Once established this will provide a vital habitat for native Little Brown Bats (Myotis lucifugus). Native bat species help control populations of mosquito, beetles and other pests, a single little brown bat can catch 600 mosquitoes in just one hour! Bats also help with pollination.

Water Quality Improvements

Planting for Clean Water 

Nassau County SWCD helped build Rain Gardens with the help of a grant from the National Fish and Wildlife Foundation. Helping reduce pollution and excess nutrients carried by stormwater. These gardens were strategically located in areas with impermeable surfaces to collect the most stormwater runoff. 

Ecological Restoration at Mill Pond 

Nassau County SWCD helped restore the coastline at Mill pond by removing invasive plants threatening the health of the coastline. The area was replanted with Spartina alterniflora also known as cordgrass (an essential native  deciduous grass that is a perennial found in many intertidal wetlands) to help reduce erosion and improve water quality.
