Phragmites australis, common reed, is an invasive species present throughout North America. It is also found on San Salvador Island in the Bahamas. The spread of Phragmites is a serious issue for the health and biodiversity of wetland habitats throughout the world, but invasive haplotypes are threatening such communities as they choke out other species, including native Phragmites. This study sought to discover the Phragmites australis haplotypes present on San Salvador Island, and consequently determine the risk of invasion for the island wetlands. Of the 10 samples from two separate sites that were taken, all were the Gulf Coast (I) haplotype, one that is likely native to the region. Therefore it is not likely that the Phragmites populations on San Salvador Island are currently under invasion by nonnative haplotypes.
