Purple Loosestrife Biocontrol Monitoring
The Cambridge Water Department and Friends of Fresh Pond Reservation have collaborated since 2006 on a project using beetles to control the growth of purple loosestrife (Lythrum salicaria), an invasive wetland plant. During today'sprogram, participants measured and counted stems on the Loosestrife plants that grow near Little Fresh Pond to determine how much of an impact the beetles have had.
