DEC Announces Completion of New York’s First-Ever Pollinator Distribution Survey

 

New York Natural Heritage Program (NYNHP) recently completed the multi-year Empire State Native Pollinator Survey. The pollinator survey documents the conservation status of 451 species. This included a wide array of native insect pollinators, including four groups of bees, two groups of flies, two groups of beetles, and two groups of moths. This inventory of the state’s native pollinators was recommended in the New York’s Pollinator Protection Plan (PDF).

Some highlights of the survey:

  • NYNHP conducted hundreds of field surveys all over New York and compiled data from museum collections and observations from community/citizen scientists—this totaled over 230,000 insect records!
  • Hundreds of volunteers provided tens of thousands of insect specimens and photographs.
  • The project added 16 bee and fly species to the known pollinators in New York State, but 79 species that were once recorded could not be found.
  • NYNHP determined that 38% of New York’s native pollinators are at risk of extirpation (becoming regionally extinct). In the worst-case scenario, as much as 60% of native insect pollinators may be at risk.

“This new multi-year survey provides critical baseline information about hundreds of pollinator species in New York,” Commissioner Seggos said. “With the assistance of our academic and other expert partners, the survey helps assess the health of these species, which are critically important for our environment and our economy, and identifies recommendations to help restore pollinator populations in the future.”

In 2016, concerns over global declines in pollinators led to creation of New York’s Pollinator Protection Plan (PDF), which called for an inventory of the state’s native pollinators. With support from the Using New York State’s Environmental Protection Fund, DEC contracted with the New York Natural Heritage Program (NYNHP) to develop and implement the survey. The full survey can be found at the NYNHP website. The goal of the project was to determine the conservation status of a wide array of native insect pollinators, including four groups of bees, two groups of flies, two groups of beetles, and two groups of moths. Butterflies were not included because the current status of butterflies is better understood than the other species studied.

To help design the survey, NYNHP assembled a team of experts from DEC, the State University of New York (SUNY) College of Environmental Science and Forestry (ESF), Cornell University, SUNY Cobleskill, the U.S. Geological Survey, the U.S. Fish and Wildlife Service, the American Museum of Natural History, the New York State Museum, Vermont Center for Ecostudies, and the Xerces Society for Invertebrate Conservation. During the project, biologists conducted hundreds of field surveys across the state, compiled data from museum collections, and reviewed observations from citizen scientists. Hundreds of volunteers provided tens of thousands of insect specimens, photographs, and observations. In total, biologists gathered more than 230,000 insect records. Using data from the study, NYNHP scientists generated maps of current and historical distributions and seasonal observation charts for 451 species.

One of the biggest take-aways from our New York State Pollinator Protection Plan was the critical need for continued research to broaden our understanding of pollinator decline,” said State Agriculture Commissioner Richard A. Ball. “We have been working to ensure funding is consistently directed in this area and have seen tremendous results with research conducted by Cornell, and now with this survey, which provides us important insight into our pollinator populations and the future of this crucial sector to agriculture.”

 

Findings from the study confirm concerns about the health of some pollinator populations in New York State. The survey found that between 38 and 60 percent of the species studied are potentially imperiled or critically imperiled. Although the survey documented 16 bee and fly species for the first time in New York State, recent sightings or records could not be confirmed for 79 pollinator species previously recorded in New York. The study found that more than one-third of the native pollinators surveyed are at risk of becoming extinct in New York.

Pollinator populations can be helped by conserving habitat, controlling invasive plants, changing mowing regimes, converting lawns into meadows, paying attention to the siting and density of honey bee hives to reduce competition and spread of disease to native species, controlling deer browsing of the understory, retaining logs and snags in forests, and reducing unnecessary outdoor lights for nocturnal species. Consistent with the Pollinator Plan, DEC is advancing actions to protect habitats and further research to study the causes of pollinator loss.

Pesticides also represent one of many factors that stress pollinators, and neonicotinoids, in particular, have been identified as a group of pesticides that, in general, are highly toxic to pollinators. Reducing pesticide use is another key way to help pollinators and earlier this year, DEC announced actions to limit the unrestricted use of pesticides that can harm bee and other pollinator populations. DEC is reclassifying certain products containing the neonicotinoid (neonic) insecticides imidacloprid, thiamethoxam, and acetamiprid as “restricted use” to ensure applications are limited to trained pesticide applicators in specific situations. Restricting the use of these pesticides enables DEC to collect new data to determine where, when, and how they are used, as well as their potential impacts. For more information, go to DEC’s website.

Management considerations for pollinator conservation include conserving habitat, reducing pesticides, controlling invasive plants, changing mowing regimes, converting lawns into meadows, discouraging high densities of honeybee hives, controlling deer browsing of the understory, retaining logs and snags in forests, and maintaining dark skies for nocturnal species.

    We should add a tax break for acreage converted into meadows and wildlife areas to help incentivize more conversion.
    Certain insecticides like neonicotinoids should be banned. Long term insecticides that persist from months to years are just too dangerous for broad use with the massive implications of destroying pollinators that are so essential to all levels of food and plant reproduction.
