This is the story of a new EREN project, designed for summer research students, trying to move beyond the pilot phase. The biennial herb garlic mustard has invaded forest understories and edge habitats in patchy, fluctuating distributions throughout the US. In the field we investigated the variation in plant performance and soil phosphorus availability, and in replicated greenhouse experiments we tested the association between rosette size and coarse woody debris. EREN’s multi-site network is ideal for studying ubiquitous invaders; however, we have struggled in finding responses larger than the site variations. Challenges and future directions will be discussed.
