Monique's research examined the effects of two treatment types for removing Ammophila arenaria (European beachgrass) from coastal sand dunes. Her study focused on the effects of manual and mechanical removal of A. arenaria on the native plant population as well as changes to the overall morphology of the dunes between invaded and restored areas. Native vegetation populations were assessed by vegetation surveys at Little River, Prairie Creek and Tolowa Dunes State Parks. Elevation was measured by RTK and UAV measurements at the same parks. This research is intended to assist land managers to choose the removal technique that affords the best long term benefit to the non-target parameters.
