SWD incidence via CAPS Survey results are tracked nationally by NAPIS - National Agricultural Pest Information System, hosted by CERIS - Center for Environmental and Regulatory Information Systems. Survey results are reported at the county level and indicate whether SWD was found by surveys or other means, and whether eradication is being attempted (currently for a part of Rhode Island only).
