    Executive Summary

    Georgia is home to more than 12,000 miles of streams, more than 500,000 acres of

    reservoirs, 192 miles of coast, and 2,300 miles of tidal waterways. The variety of aquatic

    native species found in Georgia is in part a reflection of the wide range of aquatic

    habitats within the state. From the north Georgia mountains, to the low rolling hills of

    central Georgia, to the swampy lowland, marshes and barrier islands of the coast, the

    state’s various ecosystems make Georgia the sixth most biologically diverse state in the

    Union. Additionally, Georgia ranks second in amphibian diversity, third in freshwater fish

    diversity, and seventh in vascular plant diversity. Existing along with all these native

    species, however, are many nonnative species that have been introduced into the

    state. While many of these species are relatively benign, a few of them cause

    significant negative impacts. Nonnative species that are harmful are defined as

    invasive, and those invasive species that threaten the diversity or abundance of native

    aquatic species, the ecological stability of infested waters, or the commercial,

    agricultural, aquacultural, or recreational activities dependent on such waters are

    defined as aquatic nuisance species (ANS).

    In response to this ANS challenge, the Georgia Invasive Species Advisory Committee

    (Committee) developed the Georgia Aquatic Nuisance Species Management Plan to

    describe the nature and extent of this environmental problem, and propose specific

    management actions to minimize negative impacts. Given the tremendous scope and

    complexity of the ANS problem in Georgia, Committee members did not attempt to

    outline detailed management programs for various groups of ANS. Rather, they sought

    to develop a document that could serve as a framework to facilitate such critical

    efforts in the future by summarizing current activities and priorities relating to ANS

    management, identifying gaps in programs and authorities, and providing

    recommendations for future additions and enhancements. This Committee also

    developed a Georgia Invasive Species Strategy that will serve as the State’s guiding

    document for management of terrestrial and aquatic invasive species control efforts in

    the coming years (GA DNR 2009). Georgia’s ANS Management Plan is a stand-alone

    plan, but has been incorporated into the Georgia Invasive Species Strategy.

    The Committee used information from existing reports and databases, from ANS lists in

    adjacent states, and from the knowledge and expertise of individual Committee

    members to identify ANS threats, Georgia’s existing resources for dealing with ANS, and

    new tools and additional prog
