G. Proposed Legislation • A comprehensive statute that would establish the ISDA as the lead agency responsible for permitting, funding, research, public education, program organization and coordination is needed. • An earmarked source of funding needs to be identified that will allocate sufficient and recurring funds to an Idaho Aquatic Plant Management Trust Fund. • The Idaho Aquatic Nuisance Species Task Force should be established by legislation to provide for interagency and public coordination and input into the development of long term strategy and policy, educational opportunities, and research concerning the control of nuisance aquatic species. The ISDA should also have the authority to establish other councils and committees as needed to carry out its responsibilities. VI. Idaho’s Regionalized Management Approach Idaho is a geographically diverse state. Given the differences in water bodies and Eurasian watermilfoil infestation levels statewide, a Regionalized Management Approach has been developed. The approach aims to prioritize areas based on local conditions. Each of the three regions (North, Southwest and East) has its own set of Goals and Tasks (Figure 3). These Goals and Tasks can be classified as “Prevention,” “Containment,” and “Eradication.” Management strategies in all of these regions are adaptive. That is, the management process integrates the lessons learned from outcomes of previous management activities into current conditions. This type of strategy requires periodic monitoring for effectiveness and management as a long term process rather than a one time event. The regionalized approach should also have components which aim to educate and inform permanent residents and visitors about Eurasian watermilfoil. It is important to inform these audiences as to how Eurasian watermilfoil is transported and how accidental and deliberate introductions of aquatic nuisance species can be prevented. 9

North Idaho North Idaho is characterized by many natural lakes and water bodies. The area has extensive glacial valleys with many wetlands and open water areas. The surrounding geography is characterized by coniferous forest, open granite peaks, talus slopes and permeable well drained granitic soils which are at risk for invasion by many terrestrial invasive species. In contrast to the rest of Idaho, irrigation and agriculture is not the primary use of the water resources. Recreation, 10
