Global Garlic Mustard Field Survey


Help scientists gather much-needed data on the abundance and distribution of an invasive plant called 'garlic mustard' (scientific name: Alliaria petiolata).

Many invasive species, like garlic mustard, are quickly changing North America's ecosystems, but scientists still don't understand why or how this happens. Maybe it's an escape from enemies, maybe it's an increase in size or seed production, or maybe it's a misperception.

To figure this out we need sample data from all over the world, but that requires a large group effort. Fortunately, it does not require specialized training because plant performance can be reliably quantified with simple measurements such as height and seed production of individuals, as well as area of coverage and density of plants.

By spending as little as a single day on this project, you could help scientists to come to a new understanding about invasive species. This in turn could ultimately lead to important new management strategies.
