This webinar focuses on the mechanisms of Phragmites spread. Until recently, it was believed that the spread of non-native Phragmites was driven by rhizomes in the soil, and that the seeds very had low viability. Recent research suggests that spread via seed dispersal is more significant than previously thought. The speaker discusses how Phragmites spreads, the impact of genetic diversity and nutrient enrichment on viable seed production, and the implications of spread by seed for Phragmites management.
