Invasive alien species (IAS), including aquatic invasive alien rodents (AIAR), cause extensive damage to ecosystems with significant economic, human health, and environmental concerns.In France, AIAR populations are well established, and a permanent control programme has been set up in several areas to reduce their impact.While some studies have reported the results of AIAR control activities, detailed information on current management strategies and how control activities are implemented in the field is lacking.This study evaluates the implementation of the management plan and control activities of AIAR in France regarding (i) problem definition, feasibility and objectives, (ii) planning from action plan, organization, funding and methods, (iii) field implementation from spatial prioritisation and personnel and (iv) monitoring and evaluation.Our study reveals that in France, (i) local and regional institutions mainly manage control activities primarily through volunteers and (ii) national and regional management plans on AIAR controls are missing.We elaborate on several actions that can help local and regional entities in improving their control programme, including zonation for priority actions, development of performance indicators of control activities, engagement of volunteers, and scientific monitoring of AIAR populations.
