Berberis aquifolium Invasive Species Management Treatment Data
Description
Experimental data from a management treatment study of invasive Berberis aquifolium (Oregon grape) plants conducted across four heavily infested dune sites in Belgium. The study evaluated the effectiveness of different management treatments on individual plants, with regrowth assessments conducted at 6 months and 1 year post-treatment.
