control

direct action(s) taken to reduce or suppress the distribution, abundance, spread and impacts of invasive alien species within a defined geographic area (FAO, 1995) (see management).

containment

the application of measures in and around an infested area to prevent spread of invasive alien species. Containment may also apply in the context of keeping an invasive alien species out of a defined geographic region within a broader infestation (in pest management this is also termed area-wide management) (FAO, 2019). Any action taken to delimit the distribution of an invasive alien species through whatever means possible.

closed water systems

in the context of management of biological invasions, bodies of water that do not directly or indirectly drain with continuous and intensive flow into an ocean or river, recognizing that no natural systems may be entirely closed (e.g., some inland surface waters and water bodies/freshwater)

citizen science_ias

diverse range of approaches in which scientific research is conducted, in whole or in part, by volunteers with varying levels of expertise (also known as community science, participatory monitoring, community-based environmental monitoring, crowd science, crowd-sourced science, civic science, or volunteer monitoring). Citizen science often contributes to surveillance of invasive alien species
