Pulling Perennial Pepperweed

On Saturday June 7th, from 1-4pm, the Parker River National Wildlife Refuge will host an information and training session on the identification and control of Perennial Pepperweed (Lepidium latifolium). The training will be in Newburyport, MA at PRNWF Headquarters (6 Plum Island Turnpike). The first hour will be spent indoors learning about Pepperweed and control techniques, then participants are invited to gain hands-on experience by pulling Pepperweed at a site along the Plum Island Turnpike. This meeting is open to the public with no obligation to volunteer.

Perennial Pepperweed is an invasive plant that occurs in wetland habitats along coastal areas of Massachusetts, including salt marshes, and is also found along roadsides. In the western part of the USA, it is a major agricultural weed. It can be spread through soil or water movement, or as a contaminant in hay bales.

Throughout the summer, Parker River NWR and the Massachusetts Audubon society will be leading Pepperweed pulls at sites throughout Essex County. The goal is to control or eradicate pepperweed before it becomes as pervasive as other wetland invasives, like Phragmites or purple loosestrife. If you are interested in volunteering for this project but cannot make the June 7th training session, you can contact Sarah Janson (
