In July 2005, Hempstead Town completed the first phase of a five-year plan to preserve a 40-acre Lido Beach site located along Lido Boulevard. The development of this nature area included the removal of debris and replanting of indigenous plants in areas that have been damaged over the years, creation of an earth berm to mitigate street noise into the area and construction of a scenic overlook area and parking lot. Future phases will include interpretive displays, a circular trail through the preserve area, a walkout to the bay and benches for visitors to relax and view nature's bounty.

The Lido Beach Passive Nature Area is a key component of a plan to restore more than 2,200 acres of tidal wetlands. Seventy-five percent of the property is marsh, which is an essential element of the south shore's ecosystem. The area supports a wide variety of grasses, vegetation and marine life, including several species of fish and shellfish. The conservation area is also part of the Atlantic Flyway, where various species of waterfowl inhabit the marshes during their spring and fall migrations. This estuary area is a multi-faceted project focused on habitat restoration and preservation, as well as public education.
