Global Garlic Mustard Field Survey
Many citizen science projects seek to measure the health of native species in an ecosystem. But what about measuring the advance of an invasive exotic species? That’s exactly what the Global Garlic Mustard Field Survey aims to do.

It is widely believed that invasive species are larger, reproduce more and reach higher
densities compared to their native ancestors. However, there are surprisingly few hard
data to support this claim, even for some of the most well?known invaders. One of the
most problematic invaders in North America is garlic mustard (Alliaria petiolata), yet
without good field data, important questions remain unanswered. Does garlic mustard
really grow larger and reproduce better in North American populations than in native
European populations? How much variation in performance is there among
populations within Europe and North America? Answers to questions like these will
ultimately lead to better understanding and management of invasive species.
