Global Garlic Mustard Field Survey 2012 |
1. Introduction
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). Does garlic mustard really grow larger and reproduce better in North American populations than in native European populations? Or is this species just as ‘invasive’ in its native range? How much variation in performance is there among populations within Europe and North America? How does climate affect growth and reproduction? Answers to questions like these will ultimately lead to better understanding and management of invasive species.
