Effects of Hurricane Katrina on an incipient population of giant salvinia Salvinia molesta in the lower Pascagoula River, Mississippi

The objectives of this study were to: 1) survey the lower Pascagoula River Basin and determine the post–storm distribution and abundance of giant salvinia; 2) control any remaining giant salvinia through physical and/or chemical means; 3) determine the fate of the bio–control agents; and 4) determine if re–introduction of salvinia weevils is needed and if so, to decide where best to release them.
