Grants Respond to the Spread of Invasive Mussels in the West

LAS VEGAS –  "As quagga and zebra mussels spread to the Western United States, they can have devastating ecological and economic impacts as already seen in the east and central United States. We must address the spread of these invasive aquatic species, which threaten our Nation’s natural resources, water delivery systems, hydroelectric facilities, agriculture, and recreational boating and fishing," said Ken Salazar, Secretary of the Interior.

Invasive species are among the primary factors that have led to the decline of native fish and wildlife populations in the United States and one of the most significant natural resource management challenges. A paper published in 2005 in the journal Ecological Economics estimated the cost of invasive species impacts to be approximately $120 billion each year in the United States. We continue to face enormous economic and environmental consequences as a result of invasive, nonnative species spreading in our waterways and on our lands.

The University of Nevada-Las Vegas received $218,000 for two projects it will undertake in Nevada:Using pressurized hot water spray to kill and remove dressenid mussels on watercraft: field testing on the efficacy of water temperature, high pressure, and duration of exposureDevelop effective decontamination protocols for wildland firefighting equipment to quagga/zebra mussels: testing the efficacy of quaternary ammonium compounds on killing dressenid veligers and adults -

$118,283 in Service funds and in-kind matching in time. This project will investigate the effectiveness of quaternary ammonium compounds (common cleaning agents used in homes, etc.) in killing quagga and zebra mussels to develop decontamination protocols for wildland firefighting equipment exposed to quagga and zebra mussels. - $100,378 in Service funds and in-kind matching in time. This project will develop a standard protocol for killing and removing 100% of the quagga and zebra mussels for watercraft decontamination with pressurized water spray.

"The projects selected for funding are focused on high priority action items that were identified in the plan," said Ronald Smith, Aquatic Invasive Species Program Coordinator for the Service’s Pacific Southwest Region. "Implementation of these projects will help protect western waters from infestation by quagga/zebra mussels."

Once established these invasive mussels can clog water intake and delivery pipes and dam intake gates. They adhere to boats, pilings, and most hard and some soft substrates. The mussels negatively impact water delivery systems, fire protection, and irrigation systems and require costly removal maintenance. The spread of quagga and zebra mussels across the West brings the potential to extend devastating impacts into a geographic area already challenged with severe water-related problems.

The QZAP provides a common sense approach to guide collective efforts of those fighting the westward spread of quagga and zebra mussels. Efforts funded in this round of grants include:

Early-detection monitoring programs for quagga and zebra mussels;

  • Developing a manual describing containment activities in infested water bodies;
  • Refining hot water decontamination methods for watercraft;
  • Refining decontamination methods for wildland firefighting equipment;
  • Pilot laboratory testing program for the early detection of larval mussels;
  • Invasive mussel early detection monitoring methods and quality assurance workshops;
  • Creating and implementing uniform minimum protocols and standards for watercraft interception and decontamination programs; and
  • Developing standard and effective equipment (non-watercraft) inspection and decontamination protocols.

The Service also has provided support for quagga and zebra mussel efforts through regional projects under the 100th Meridian Initiative (www.100thmeridian.org), a cooperative effort between local, state, provincial, regional, and federal agencies to prevent the westward spread of zebra/quagga mussels and other aquatic nuisance species in North America. In addition, the Service, through the Aquatic Nuisance Species Task Force, has funded implementation of State and Interstate Aquatic Nuisance Species Management Plans. These plans describe detection and monitoring efforts of aquatic nuisance species, prevention efforts to stop their introduction and spread, and control efforts to reduce their impacts.

Contact: Dan Balduini (702) 515-5480The U.S. Fish and Wildlife Service (Service) announced today that nearly $600,000 will be awarded to nine projects targeting three of the highest priorities from the Quagga-Zebra Mussel Action Plan for Western U.S. Waters (QZAP). Two of the projects will be implemented in Nevada.
