After a species becomes established, management options include containment, control, and, if possible, eradication. Containment efforts are used to prevent further spread of the targeted ANS, while control efforts are used to suppress ANS populations so that other resource management objectives can be achieved. Control measures may include mechanical, chemical, biological, and integrated pest management strategies. Adequate funding, public awareness, and management expertise are critical to success, particularly because ANS can span geographic and jurisdictional boundaries. Habitat and ecosystem restoration should be conducted whenever the control or eradication of ANS is planned since rehabilitation is often necessary to restore ecological processes. Restoration activities may include planting or stocking organisms or improving predator-prey relationships to attain food webs similar to pre-invasion conditions.

State  ANS Management Plan

The ANS Task Force provides guidance to facilitate development of ANS management plans for states. Once approved by the ANS Task Force, the actions identified by the plan are undertaken by state agencies, local programs, cooperating federal agencies, and others to prevent and control ANS infestations in an environmentally sound manner. Currently, the following states (or interstate geographical areas) have management plans approved by the ANS Task Force:
