The impacts of Arundo donax infestations on channelization and stream fishes need to be 
researched. 
Remote sensing and acreage estimations need to be performed for Arundo donax , 
salvinia, water hyacinth, waterlettuce, saltcedar, and other aquatic invasive vegetation. 
The impacts of Eurasian watermilfoil weevils on Myriophyllum spicatum in the Rio 
Grande need to be evaluated. 
Research on the applesnail infestations of Texas rice crops and native riparian vegetation 
needs to be conducted. 
Chinese tallow control efforts need to be evaluated. 
The impacts of grass carp on the Galveston Bay Ecosystem; the impacts of Arundo donax 
wasps on giant reed populations; and the conditions for hydrilla expansion should be 
researched. 
Aquatic invasive species (AIS) should be monitored and tracked in freshwater and 
estuarine systems to facilitate early detection and rapid response. 
Research needs to be conducted on the ecological, social, and economic impacts of 
emerging AIS in Texas’s coastal watersheds, bays, and estuaries.
