Phragmites: Introduction

The common reed Phragmites australis has a worldwide distribution. Over the past 150 years this reed has become much more widespread and abundant in North America and is considered invasive in some parts of its range. Phragmites in North America can presently be divided into three genetic groupings: native lineages, a Gulf Coast lineage, and a non-native lineage. The non-native haplotype is an aggressive invader and has outcompeted and replaced virtually all native haplotypes along the east coast of the United States.  

  

Previous Activities

  • A statewide survey in 2010 did not find the invasive Eurasian Phragmites, but a small population was found in 2013 in Pinellas County.
  • A second statewide survey is planned for the fall of 2015.
