The Development and Evaluation of a Freshwater Mussel Sampling
THE DEVELOPMENT AND EVALUATION OF A FRESHWATER MUSSEL SAMPLING PROTOCOL FOR A LARGE LOWLAND RIVER by JASON RAY MEADOR Under the direction of James T. Peterson ABSTRACT Freshwater mussels are among the most imperiled aquatic species within the southeastern United States. Mangers are faced with the task gathering information via monitoring, and making decisions based on available information about local mussel populations. I gathered data on mussel behavior, demography, distribution, and detection to develop a cost-effective protocol for monitoring freshwater mussel populations within the Altamaha River. Surface abundance, survival, occupancy, and detection varied spatially, temporally, and among species. I then developed sampling stratum within mesohabitats based on empirical data and evaluated the efficacy of several sampling protocols via simulation. Spatial and temporal variation among species emphasize the importance for properly estimating and evaluating habitat based on use and detection and suggest refraining from raw count indices.

As a result, the current status of the endemic among malacologists for its high percentage (ca. 40%) of mussels of the lower Altamaha River system was reviewed. endemic mussels. While little historical data exists to This review will provide information to policy makers and quantify changes in mussel abundance, many biologists regulatory agencies for developing conservation strategies believe that some species are declining. We assembled a that may affect the persistence and habitat quality of large database of mussel occurrence records from imperiled mussels. surveys conducted since 1967 and used this data to assess the current status of endemic mussels in the lower Ocmulgee and Altamaha rivers.

South Carolina Landscape Management Plan
AMERICAN TREE FARM SYSTEM® LANDSCAPE MANAGEMENT PLAN State of South Carolina i Landscape Management Plan Creation Plan Development and Composition The American Forest Foundation (AFF), in conjunction with Southern Forestry Consultants, Inc.(SFC), developed the original components, outlines, structure, and drafts of the Landscape Management Plan (LMP) and the associated geodatabase. AFF and SFC also worked cooperatively to evaluate and incorporate edits, comments, and modifications that resulted in the final LMP and geodatabase. Natural Resource Professional Support Committee AFF consulted regularly with staff from the South Carolina Forestry Commission (SCFC) to seek their input on various thematic, structural, and scientific components through multiple drafts of this LMP. Additionally, SCFC staff facilitated access to and procurement of publicly available geospatial data during the development of the geodatabase. Additional Stakeholders AFF also sought input from a variety of additional stakeholders with expertise in the natural resources, planning, certification, and regulatory disciplines. Like the Support Committee, these additional stakeholders did not necessarily endorse all components of the LMP, nor does AFF imply a consensus was reached. These additional stakeholders included: • American Forest Management • SC Department of Agriculture • Association of Consulting Foresters • SC Department of Natural Resources (DNR) • Audubon South Carolina • SC Native Plant Society • Belle W.

Altamaha Archmussel (Alasmidonta Arcula)
Supplemental Volume: Species of Conservation Concern SC SWAP 2015 Altamaha Arcmussel Photo by John Alderman Alasmidonta arcula Contributor (2012): William Poly (SCDNR) DESCRIPTION Taxonomy and Basic Description The shell of the Altamaha Arcmussel is triangular in outline and inflated with a rounded anterior end and a truncated posterior end. The umbo is high above the hinge line near the center of the shell. The outer surface is generally smooth except on the posterior slope; the coloration is dull greenish-yellow with green rays, becoming darker in mature individuals. The inner shell surface is bluish-white or white. Maximum shell length for this species is 75 mm (2.9 in.) (Johnson 1970). It is tentatively included in the South Carolina fauna pending completion of a current project on Alasmidonta spp. (Arthur Bogan pers. comm.). Status The Altamaha Arcmussel is listed as endangered in the IUCN Red List of Threatened Species (Bogan and Seddon 2000). The current global status for the Altamaha Arcmussel is imperiled (G2), and it is listed as imperiled (S2) in Georgia as well. It is not ranked in South Carolina (NatureServe 2011), but it is recommended for a rank of S2. POPULATION SIZE AND DISTRIBUTION The Altamaha Arcmussel was thought to be restricted to the Altamaha River system in Georgia (Johnson 1970). Now it is known from several rivers of the Altamaha River system in Georgia, including the Ocmulgee, Little Ocmulgee, Ohoopee, and Altamaha Rivers to the Ogeechee and Savannah Rivers in Georgia and South Carolina. It was found only recently in the Savannah River downstream of Augusta (NatureServe 2011). -

Altamaha arcmussel (Alasmidonta arcula) 60 mm (2 inches). Altamaha River, Wayne Co., Georgia. Photo by Jason Wisniewski, GA DNR. Common Name: ALTAMAHA ARCMUSSEL Scientific Name: Alasmidonta arcula Lea Other Commonly Used Names: none Previously Used Scientific Names: none Family: Unionidae Rarity Ranks: G1/S1 State Legal Status: Threatened Federal Legal Status: none Description: Shell is delicate, inflated, often with distinct concentric sculpturing near the umbo. Rarely exceeds 80 mm (3 inches) in length. Umbos are elevated above the hingeline and positioned centrally to slightly anterior of the triangulate shell. Adults typically have brown to yellow periostracum with dark rays. Posterior ridge is sharp and straight. Right valve has one delicate pseudocardinal tooth and a short, delicate lateral tooth. Left valve has one to two delicate, serrated pseudocardinal teeth with lateral teeth absent or reduced. Beak cavity is shallow and nacre is typically white or iridescent. Similar Species: None. Habitat: Typically found in sloughs, oxbows, or depositional areas in large creeks to large rivers with silt, mud, and/or sand substrates. The Altamaha arcmussel is associated with a wide range of substrates from coarse sand to medium silt, but this species was most commonly found in fine sand. In 2007, surveys of the Altamaha River found individuals most frequently occupying areas with gently sloping banks, often times with low hanging willows and soft mud. Individuals were less frequently encountered in other habitats, but were sometimes found in coarse sand and gravel substrates in pools of 2 - 3 meters (6 - 9 feet) deep. Diet: The diets of unionids are poorly understood but are believed to consist of algae and/or bacteria. -

We recognize a total of 298 species in 55 genera in the families Margaritiferidae (one genus, five species) and Unionidae (54 genera, 293 species). We propose one change in the Margaritiferidae: the placement of the formerly monotypic genus Cumberlandia in the synonymy of Margaritifera. In the Unionidae, we recognize three new genera, elevate four genera from synonymy, and place three previously recognized genera in synonymy. -
Conservation Action Plan
Conserving the ALTAMAHA RIVER WATERSHED CONSERVATION ACTION PLAN November 2005 Preface As stated in Conservation by Design, The Nature Conservancy’s conservation goal is “the long term survival of all viable native species and community types” within portfolios of sites by ecoregion. In order to accomplish the ambitious goal of conserving all native biodiversity, the Conservancy has developed many tools for conservation planning at the ecoregional and site- based scale. The Altamaha River Watershed has long been a priority for The Nature Conservancy (TNC) based on its freshwater resources, rare species and critical ecological linkage to its rich estuary and Atlantic Ocean. The rivers and much of the terrestrial landscape found within the project have been identified as significant sites through the South Atlantic Coastal Plain ecoregional planning process. The Nature Conservancy has been involved in conservation planning for the Altamaha River Watershed since 1997. During this time, TNC has utilized a series of workshops to address conservation strategies at the site scale. The goal of these workshops was to apply The Nature Conservancy’s site conservation “5-S Framework” to the Altamaha River Watershed project area, thereby developing a conservation blueprint for action and a baseline from which to measure its success over time. During calendar year 2005, the TNC-Georgia Conservation staff revised the Altamaha plan through another series of workshops in collaboration with the Southeast Aquatic Resource Partnership (SARP). The SARP chose the Altamaha River as one of four pilot watersheds in the Southeastern U.S. (the Altamaha in GA, the Roanoke River in NC & VA, the Duck River in TN, and the Pascagoula River in MS) to test the development of a Southeastern Aquatic Habitat Plan. -

Alasmidonta Triangulata Scaled
Southern elktoe (Alasmidonta triangulata) Specimen unmeasured. Uchee Creek, Russell Co., Alabama. Photo by Jason Wisniewski, GA DNR. Specimen provided by the Florida Museum of Natural History. Common Name: SOUTHERN ELKTOE Scientific Name: Alasmidonta triangulata Lea Other Commonly Used Names: none Previously Used Scientific Names: none Family: Unionidae Rarity Ranks: G1/S1 State Legal Status: Endangered Federal Legal Status: none Description: The southern elktoe has a moderately thin, inflated shell, often with distinct concentric sculpturing originating at the umbo and rarely exceeding 70 mm (2 inches) in length. Umbos are elevated above the hingeline and positioned to the anterior portion of the sub- triangular shell. Anterior margin of shell is rounded while posterior margin is bluntly pointed. Posterior ridge sharp angular. Adults typically with dark brown to black periostracum with faint rays while young individuals have yellow to green with green rays present. Left valve often with two compressed, poorly developed pseudocardinal teeth and reduced or absent lateral tooth. Right valve with one compressed, high pseudocardinal tooth and lateral teeth reduced or absent. Umbo cavity is deep and nacre white. Similar Species: Triangle floater (Alasmidonta undulata) and Altamaha arcmussel (Alasmidonta arcula). Little conchological difference exists between these species. As a result, these specimens may be best identified using a combination of genetics and biogeography. Habitat: Typically occupies large creeks to large rivers with soft substrates of silt, mud, sand, or gravel, often in backwaters and pools. Diet: The diets of unionids are poorly understood but are believed to consist of algae and/or bacteria. Some studies suggest that diets may change throughout the life of a unionid with juveniles collecting organic materials from the substrate though pedal feeding and then developing the ability to filter feed during adulthood.
