Population [top]

Population:The species range is greater than 10,000 km² but population densities are likely to be low throughout this area (Ewert 1997), It is naturally rare in northern extremes of its range. Klemens and Behler (1997) report that there is good anecdotal evidence that the species is undergoing a long-term, non cyclical decline throughout much of its range.

Habitat and Ecology [top]

Habitat and Ecology:Some natural habitat has been drained and replaced by agriculture in recent years, however, actual habitat loss, in terms of loss of rivers and their banks, may be small (Ewert 1997). The turtle has been found in reservoirs throughout their range and dyking of rivers to create winter waterfowl refuges has increased potential habitat in Arkansas and the lower Mississippi Valley and may offset some of the degraded habitat (Ewert 1997).
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): The main threats include habitat alteration; exploitation by trappers for a large domestic market and a growing international market for its meat; pollution and pesticide accumulation (Holt and Tolson 1993).
