Area of Occupancy: 2,501 to >12,500 4-km2 grid cells
Area of Occupancy Comments:  

Number of Occurrences: > 300
Number of Occurrences Comments: In Minnesota, it is in the Red River of the North, Minnesota, and St. Croix drainages, and Mississippi River drainage below St. Anthony Falls; rare in the Rainy River drainage and SE streams (Sietman, 2003; Graf, 1997; Cvancara, 1970); also Lake of the Woods (Hove et al., 1997). In Illinois, it is sporadic in the northern half, in half the drainages it once occupied (Cummings and Mayer, 1997; Schanzle and Cummings, 1991) but healthy in Vermillion (Wabash drainage) and Kankakee systems (Schanzle et al., 2004); Fox and other upper Illinois basins with some decline (esp. in Wisconsin) (Sietman et al., 2001; Schanzle et al., 2004). Indiana distribution: Tippecanoe (Cummings and Berlocher, 1990), East Fork White (Harmon, 1992), Muscatatuck (Harmon, 1989), St. Joseph and Maumee (Pryor, 2005). It is widespread but sporadic in glaciated Ohio (Watters, 1992; 1995; Lyons et al., 2007; Grabarciewicz, 2008; Watters et al., 2009). In West Virginia, it occurs in the Mud (Guyandotte drainage) (Schmidt and Zeto, 1986) and Upper Kanawha (Morris and Taylor, 1992); and upper Clinch River, Virginia (Jones et al., 2001) incl. Copper Creek (Hanlon et al., 2009). It is in the Poteau (Vaughn and Spooner, 2004), lower Arkansas (Frog Bayou) (Gordon, 1985), Ouachita (Posey et al., 1996), and White (Gordon, 1982; Christian, 1995) River drainages, Arkansas. In Kansas, it is in the Neosho and Spring (Branson, 1966) River basins with relic shells in the Marais des Cygnes and Pottawatomie Creek (Marais des Cygnes River basin), and Fall, Elk, Big Caney, and South Fork of the Cottonwood River (Neosho River basin) (Couch, 1997). In Vermont, it is in Lake Champlain tributaries (Fichtel and Smith, 1995) in Lamoille, Winooski, Poultney Rivers, Otter and Lewis Creeks, and Missisquoi River (shells) (Kart et al., 2005). In Wisconsin, it is common and widespread except the SW section of the state (Mathiak, 1979). In Virginia, it was recently in the upper South Fork Holston (Stansbery and Clench, 1978), Powell and Clinch Rivers (Ahlstedt and Tuverville, 1997), and upper North Fork Holston River (Jones and Neves, 2007) where it is rare. In Tennessee, it is most common in east and middle Tennessee from unimpounded upper Powell and Clinch Rivers and other tributaries of the upper Tennessee system, S and W to the Elk, Duck, Stones, Big South Fork Cumberland, and Harpeth Rivers (Parmalee and Bogan, 1998). In Alabama, it is uncommon and limited to the Tennessee River system extant only in the Paint Rock and Elk Rivers and a short reach of Bear Creek in Colbert Co. (Ahlstedt, 1996; Mirarchi, 2004; Williams et al., 2008). It has been collected in Kentucky in the South Fork Kentucky (Evans, 2008), Middle Green (Gordon, 1991) and Barren Rivers (Cochran and Layzer, 1993), but is generally distributed in the Tennessee River eastward (Cicerello and Schuster, 2003) and Red River (Clark, 1988). Athearn (1992) lists a range extension into Georgia in South Chickamauga Creek in Catoosa Co. It occurs in the Lake Michigan and St. Clair drainage (Badra and Goforth, 2003), Michigan (Strayer, 1980; Trdan and Hoeh, 1993) and parts of the upper peninsula (Goodrich and Van der Schalie, 1939) and Kalamazoo River (Mulcrone and Mehlne, 2001). It is rare in Oklahoma in: Neosho, Little (Vaughn and Taylor, 1999), Glover, and Mountain Fork (Spooner and Vaughn, 2007) Rivers, and eastern tributaries of the Arkansas River (possibly historic) (Branson, 1983; Vaughn, 2000). In Canada, it is abundant in Ontario (particularly southern), the core of its Canada range, and less abundant with decline in Manitoba (Red and Winnipeg Rivers- Watson, 2000) and Quebec; likely extirpated from the St. Lawrence River (Metcalfe-Smith and Cudmore-Vokey, 2004). Clarke (1981) lists Canadian distribution as Hudson Bay drainage in the Red and Winnipeg River systems; Great Lakes-St. Lawrence system from southern Lake Huron and tributaries to the Ottawa River and Lake Champlain; and entire Ohio-Mississippi River system.

Population Size: >1,000,000 individuals
Population Size Comments: Smith and Crabtree (2010) found this species at 9 of 32 sites (5 with recruitment) along the entire length of Pennsylvania's French Creek.

Number of Occurrences with Good Viability/Integrity: Unknown

Overall Threat Impact Comments: Recently, zebra mussels were found in areas previously occupied by this species on the Rideau River in eastern Ontario (Schueler and

Short-term Trend: Relatively Stable (<=10% change)
Short-term Trend Comments: Pip (2000) was unable to find this species in Manitoba in recent surveys despite historical presence in similar surveys in 1975-1978; but it is still present there, though declining (Watson, 2000).

Long-term Trend: Decline of <30% to increase of 25%
Long-term Trend Comments: This species formerly inhabited the main channels of the Tennessee and Cumberland Rivers, as well as medium-sized rivers such as the Obey, Caney Fork, Red, Roaring, Emory, Watauga, French Broad, and Holston in Tennessee (Parmalee and Bogan, 1998). It formerly occurred in Mississippi in the Tennessee River drainage but is now extirpated (Jones et al., 2005). In Alabama it has declined from across Northern Alabama to only the Elk and Paint Rock Rivers and Bear Creek, Colbert Co. (Williams et al., 2008). Hoggarth et al. (2008) note subfossil and historic records for Symmes Creek (Raccoon basin) in Ohio.

Infestation by glochidia confirmed (though transformation not tested) on Dorosoma cepedianum, Moxostoma carinatum (Weiss and Layzer, 1995). Lefevre and Curtis (1910; 1912) cited Cyprinus carpio (common carp) as a host. Watters et al. (1999) confirmed Etheostoma zonale (banded darter), Hypentelium nigricans (northern hogsucker), Lepomis gibbosus (pumpkinseed), Micropterus salmoides (largemouth bass), Rhinichthys cataractae (longnose dace). Watters et al. (1998) also confirmed Hypentelium nigricans (northern hogsucker), Rhinichthys cataractae (longnose dace). New host fish confirmation from Watters et al.

Group Name: Freshwater Mussels

Use Class: Not applicable
Minimum Criteria for an Occurrence: Occurrences are based on some evidence of historical or current presence of single or multiple specimens, including live specimens or recently dead shells (i.e., soft tissue still attached and/or nacre still glossy and iridescent without signs of external weathering or staining), at a given location with potentially recurring existence. Weathered shells constitute a historic occurrence. Evidence is derived from reliable published observation or collection data; unpublished, though documented (i.e. government or agency reports, web sites, etc.) observation or collection data; or museum specimen information.
Mapping Guidance: Based on the separation distances outlined herein, for freshwater mussels in STANDING WATER (or backwater areas of flowing water such as oxbows and sloughs), all standing water bodies with either (1) greater than 2 km linear distance of unsuitable habitat between (i.e. lotic connections), or (2) more than 10 km of apparently unoccupied though suitable habitat (including lentic shoreline, linear distance across water bodies, and lentic water bodies with proper lotic connections), are considered separate element occurrences. Only the largest standing water bodies (with 20 km linear shoreline or greater) may have greater than one element occurrence within each. Multiple collection or observation locations in one lake, for example, would only constitute multiple occurrences in the largest lakes, and only then if there was some likelihood that unsurveyed areas between collections did not contain the element.

For freshwater mussels in FLOWING WATER conditions, occurrences are separated by a distance of more than 2 stream km of unsuitable habitat, or a distance of more than 10 stream km of apparently unoccupied though suitable habitat. Standing water between occurrences is considered suitable habitat when calculating separation distance for flowing water mussel species unless dispersal barriers (see Separation Barriers) are in place.

Several mussel species in North America occur in both standing and flowing water (see Specs Notes). Calculation of separation distance and determination of separation barriers for these taxa should take into account the environment in which the element was collected. Juvenile mussels do not follow this pattern and juveniles are typically missed by most standard sampling methods (Hastie and Cosgrove, 2002; Neves and Widlak, 1987), therefore juvenile movement is not considered when calculating separation distance.

Separation Barriers: Separation barriers within standing water bodies are based solely on separation distance (see Separation Distance-suitable, below). Separation barriers between standing water bodies and within flowing water systems include lack of lotic connections, natural barriers such as upland habitat, absence of appropriate species specific fish hosts, water depth greater than 10 meters (Cvancara, 1972; Moyle and Bacon, 1969) or anthropogenic barriers to water flow such as dams or other impoundments and high waterfalls.
Separation Distance for Unsuitable Habitat: 2 km
Separation Distance for Suitable Habitat: 10 km
Alternate Separation Procedure: None
Separation Justification: Adult freshwater mussels are largely sedentary spending their entire lives very near to the place where they first successfully settled (Coker et al., 1921; Watters, 1992). Strayer (1999) demonstrated in field trials that mussels in streams occur chiefly in flow refuges, or relatively stable areas that displayed little movement of particles during flood events. Flow refuges conceivably allow relatively immobile mussels to remain in the same general location throughout their entire lives. Movement occurs with the impetus of some stimulus (nearby water disturbance, physical removal from the water such as during collection, exposure conditions during low water, seasonal temperature change or associated diurnal cycles) and during spawning. Movement is confined to either vertical movement burrowing deeper into sediments though rarely completely beneath the surface, or horizontal movement in a distinct path often away from the area of stimulus. Vertical movement is generally seasonal with rapid descent into the sediment in autumn and gradual reappearance at the surface during spring (Amyot and Downing, 1991; 1997). Horizontal movement is generally on the order of a few meters at most and is associated with day length and during times of spawning (Amyot and Downing, 1997). Such locomotion plays little, if any, part in the distribution of freshwater mussels as these limited movements are not dispersal mechanisms. Dispersal patterns are largely speculative but have been attributed to stream size and surface geology (Strayer, 1983; Strayer and Ralley, 1993; van der Schalie, 1938), utilization of flow refuges during flood stages (Strayer, 1999), and patterns of host fish distribution during spawning periods (Haag and Warren, 1998; Watters, 1992). Lee and DeAngelis (1997) modeled the dispersal of freshwater into unoccupied habitats as a traveling wave front with a velocity ranging from 0.87 to 2.47 km/year (depending on mussel life span) with increase in glochidial attachment rate to fish having no effect on wave velocity.

Nearly all mussels require a host or hosts during the parasitic larval portion of their life cycle. Hosts are usually fish, but a few exceptional species utilize amphibians as hosts (Van Snik Gray et al., 2002; Howard, 1915) or may metamorphose without a host (Allen, 1924; Barfield et al., 1998; Lefevre and Curtis, 1911; 1912). Haag and Warren (1998) found that densities of host generalist mussels (using a variety of hosts from many different families) and displaying host specialists (using a small number of hosts usually in the same family but mussel females have behavioral modifications to attract hosts to the gravid female) were independent of the densities of their hosts. Densities of non-displaying host specialist mussels (using a small number of hosts usually in the same family but without host-attracting behavior) were correlated positively with densities of their hosts. Upstream dispersal of host fish for non-displaying host specialist mussels could, theoretically, transport mussel larvae (glochidia) over long distances through unsuitable habitat, but it is unlikely that this occurs very often. D. Strayer (personal communication) suggested a distance of at least 10 km, but a greater distance between occurrences may be necessary to constitute genetic separation of populations. As such, separation distance is based on a set, though arbitrary, distance between two known points of occurrence.
