Spotted Lanternfly & Tree-of-heaven: NY needs your help!
Spotted lanternfly (SLF) is an invasive pest from Asia that feeds on a variety of plants including grapes, hops, and maple trees, posing a severe threat to NYS forests and agriculture (more info). SLF's preferred host plant, Tree-of-heaven (TOH), is already found in much of the state. SLF was first found in PA in 2014, and several populations have since been found in NY. Agencies and conservation partners across the state are working to protect our state resources from these invasives, and we are requesting help from volunteers to complement these efforts.
Want to learn more about SLF, TOH, and volunteering? Attend one of our upcoming webinars:
SLF management actions are more effective and regions can better prepare for the impacts of this insect when new infestations are found early.
New York State is seeking volunteers like you to look for SLF and TOH in your area. You can supplement NYS efforts to prevent negative impacts from invasive species by knowing what to look for and how to report observations to New York’s official invasive species database, iMapInvasives.
NYS Department of Agriculture and Markets and the Office of Parks, Recreation, and Historic Preservation have identified 1km grid squares across the state where volunteer survey efforts would be most helpful. These may be close to known infestations, along major pathways, and/or near important commodities that could be harmed by SLF. Use the interactive map below to sign up for a grid square and survey one or two areas within that are publicly and safely accessible.

Important info for volunteers
Guidance for surveying:
Only survey areas open to the public. Review and follow all rules and regulations that pertain to the site visited, including paying parking fees, if applicable.
Stay alert and aware of surroundings when surveying parking areas and roadsides. Only survey areas that are easily and safely accessible.
Follow applicable COVID-19 protocols
Please note that agencies and partners are not obligated to remove any invasive species found

*Focus grid squares are the highest priority grid squares to claim, but you can claim any available grid square in your preferred area.
"Can I survey somewhere else?"
The grid squares were selected to drive volunteers to areas that are accessible and/or where conservation partners need the most help surveying for SLF and TOH (often focusing on areas containing publicly accessible land). However, surveys for SLF and TOH are helpful at any location, including outside of grid squares.
You can participate in this effort without signing up for a grid square by surveying for SLF and TOH and submitting observations to iMapInvasives in your own backyard, local parks, and other areas which may not be captured by grid squares.
Please login to iMap and join the "NYS SLF-TOH-iMap Volunteer Survey 2021" project to associate your records with this effort (how to join a project).
