Evidence for natural hybridization between native and introduced lineages of <i>Phragmites australis</i> in the Chesapeake Bay watershed

Although evidence of field hybridization between native and introduced lineages of Phragmites in North America is still relatively rare, the continued encroachment of the introduced lineage into native wetlands may increase the likelihood of future hybrid formation. Careful genetic monitoring to identify remnant native and potential hybrid Phragmites is essential for prioritizing ongoing management efforts.
