Seabeach Knotweed: A Plant of Special Concern

Seabeach Knotweed  (a plant of special concern) has been discovered here at the field station. In this photo, Jr. Ranger Isobel Mackinnon helps with placing markers for the GIS class from UMass. Boston so they (UMass. students) can take bearings and create an accurate map using global positioning satellite technology.  The biggest challenge for this plant is often "dune nourishment" efforts to save coastal barriers, loss of the plant (being covered over) is but one instance of what is called unintended consequences.
