After 25 years of assiduous work, the Aquatic Plant Information Retrieval System (APIRS) database now includes more than 71,000 citations, and continues to be the largest free database of its kind in the world. It contains citation and keyword records for scientific articles and reports about uncounted species of aquatic, wetland and invasive plants.
The database has been used many thousands of times by researchers, government agencies, companies, teachers, students and private groups and individuals. Users can request searches of the database or they can access the database themselves, online.
