The efficient management of these harmful species should therefore be considered a priority in conservation policy. As invasive species proliferate and new species arrive in a region, control costs are expected to increase, making the improvement of prevention and management strategies mandatory. The objective of this study is to develop a predictive model to facilitate the management of two invasive species of the genus Carpobrotus. A comprehensive understanding of the expansion patterns of a particular population is essential for the selection of suitable management strategies. The model developed in this study indicates that chemical control is the most economically efficient method. Conversely, methods involving manual removal of plant material implicate a greater number of working hours, and therefore a higher economic cost. For all three methods evaluated (mechanical removal, chemical treatment, chemical treatment with necromass removal), the total management costs increased with time. However, this cost increase was not proportional between the different methods, being much more pronounced for mechanical control. The findings underscore the pivotal role of early detection, facilitating the implementation of cost-effective mechanical eradication strategies, thereby reducing the reliance on chemical control measures.engAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/Biological invasionsControl costsDynamic modellingIceplantsPlant managementjournal articleopen access10.1016/j.flora.2025.152881
