BISON database for garlic mustard occurrence data www.currentresults.com for climate data.
Occurrence data is measured by botanists from 1967 till now, all data has been peer-reviewed and confirmed to be garlic mustard species. A garlic mustard population that has at least 20 individuals and covers 1 square meter of area will be count as 1 observation (or 1 occurrence). If the garlic mustard population is less than 20, or its dispersal is less than 1 square meter, then it will not be counted. To avoid double counts, only observation data from different locations in the same year or same location but different years are mapped.
