Make invasive species informationunderstandable, local, and usefulto protect ecosystems across the USA

Invasive Species in the USA(Is it USA?) turns county-level data into a map people can actually use.Instead of forcing people through scattered PDFs, agency pages, or state lists, the project enablesinvasive species detection & mitigation for the people who live, work, hike, fish, farm, and restore.

Data foundation

Project Isitusa is designed around county-level invasive species exploration. The current release uses a full verified lower-48 invasive species catalog from US-RIIS, plus a stored merged county presence snapshot from April 15, 2026 using EDDMaps and USGS NAS where verified county records are available. Remaining county-level gaps are surfaced explicitly in the explorer while those records continue to be filled in.
