Plan under development. 
A.13.2. AQUATIC INVASIVE SPECIES PROGRAMS AND ACTIVITIES 
• Noxious Weeds Program, Idaho State Department of Agriculture (ISDA), 
Cooperative Weed Management Area (CWMA). CWMA is a distinguishable 
hydrologic, vegetative, or geographic zone based upon geography, weed infestations, and 
climatic or human-use patterns. CWMAs are formed when the landowners and land 
managers of a given area come together and agree to work cooperatively to control 
weeds. Idaho has 40 CWMAs, which are part of the ISDA cost-share program (the 
majority of the funding comes from federal sources). There are currently several cost- 
share participants that are working to deal with aquatic species in Idaho. The ISDA is 
responsible for administering the CWMA program in Idaho. 
• Eurasian Watermilfoil (EWM) Control Program, ISDA. In response to the 
continuing economic and environmental crises created by EWM in Idaho’s waters, the 
Idaho State Legislature appropriated $4 million to the ISDA for eradication and control 
of the aquatic weed. The Legislature directed these funds to be expended over a 2-year 
period beginning July 1, 2006 and ending June 30, 2008. 
• Invasive Species Council, Governor's Office. The Idaho Invasive Species Council was 
established by Idaho’s Governor’s Executive Order in 2001. This Council is carrying out 
an inventory of EWM and conducting a public awareness campaign for boaters. The 
Invasive Species Coordinator is housed within ISDA. 
• EWM Task Force, Invasive Species Council. The EWM Task Force was formed in 
2002 to assist the Invasive Species Council in surveys and other EWM activities. The 
major activities of the Task Force include: (1) physically surveying all waters in the 
state; (2) developing a survey for all counties to prioritize actions and activities based on 
susceptibility factors; (3) engaging in multiple research projects with the University of 
Idaho (including research on control technologies); and (4) researching different 
herbicide combinations and exploring the use of new products. 
• Purple Loosestrife Control Efforts, University of Idaho. This program uses biocontrol 
for purple loosestrife. Also, outreach programs both distribute insects (-40,000 
distributed) and educate land managers on how to use them.
