Many invasive species, like Garlic Mustard (Alliaria petiolata), are threatening the world's natural resources. The abundance of Garlic Mustard is variable throughout North America and Europe, even for populations that have been established for a long time. Understanding why this variation exists could lead to important new insights into the biology of invasive species and ultimately lead to new and more effective control options

Maybe you wonder if your time would be better spent pulling out Garlic Mustard, rather than measuring it. Control efforts are important, but good scientific research will lead to much more effective control strategies.
The researchers behind the Global Garlic Mustard Field Survey project are integrating survey data with Garlic Mustard eradication efforts to track the effectiveness of different control options in different regions

Through large-scale sampling, scientists can identify areas that differ in the intensity of invasion and try to understand why these differences exist. They can also compare this to variation in the native range. This may be crucial to researching new methods of control, but a large project like this could cost millions of dollars and years of work without help from volunteers.
