EAB Watch
Six South Dakota counties are currently under the state’s Plant Pest Quarantine for emerald ash borer: Brookings, Minnehaha, Lincoln, Turner, Union, and Grant. This page tracks exactly which cities are confirmed, which sit in a quarantined county, and which aren’t affected yet — the same fact bank every guide on this site pulls from, nothing asserted without a named source.
Confirmed in City
5 citiesEAB has been directly confirmed within city limits. Treatment decisions here are time-sensitive, not preventive.
County Quarantined
4 citiesThese cities sit inside a quarantined county but aren’t individually named in a DANR confirmed-community release. Treat as county-level status, not city-specific confirmation.
Not Yet Confirmed
15 citiesNot on the current quarantine list. Monitor, don’t panic-treat — this can change, and has expanded multiple times since 2018.
How This Is Verified
Every status on this page traces to a named source: South Dakota DANR’s Plant Pest Quarantine records and individual city forestry department announcements — the same discipline behind every city fact bank on this site. Nothing here is inferred or assumed.
Check the current official list directly at emeraldashborerinsouthdakota.sd.gov, or the state forest health line at 605-394-2395, since the quarantine map is actively expanding and this page reflects the most recent confirmed update at time of research.
