The New York Dragonfly and Damselfly Survey (NYDDS) began in 2005 and spanned five field seasons through 2009. It relied heavily on citizen scientists to help collect data over a large geographic area. This was a project of the New York State Department of Environmental Conservation (NYSDEC), Division of Fish and Wildlife, and the New York Natural Heritage Program (NYNHP). It was supported with funds from the U.S. Fish and Wildlife Service State Wildlife Grants program, administered by NYSDEC. Its primary goal was to document the current distribution of all odonate species in New York State. Survey efforts were directed toward under-surveyed regions, areas with potential high diversity, and locations with potential for harboring Species of Greatest Conservation Need (SGCN).

Our five-year sampling effort yielded many important finds. Most notable were five species added to the list of known odonates for the state. This brings the cumulative total to 194 species. It is one of the highest diversities of any U.S. state.

Participants visited over 2,170 survey sites statewide. A total of 4,383 surveys were conducted, including repeat visits. We confirmed over 18,000 individual species records based on our verification protocol. NYDDS yielded 1,111 new county records beyond these preexisting data. Each county's documented richness increased by 18 species on average, and we documented at least 75 species in two-thirds of New Yorks' 62 counties. A list was compiled for each county as well as a distributional map and phenology chart for all 194 species. Full species accounts are included for all 48 SGCN.
