Eastern Sand Darter
Eastern sand darter lives in medium-sized streams and larger rivers with clean sand and low gradient. Early reports placed this species in the Erie watershed and in the Salmon River of the Saint Lawrence watershed. The Salmon River population is secure, but it has apparently declined in the Erie watershed. Since all the records from tributaries of the Saint Lawrence farther west than Salmon River, and from the Allegheny, date after 1979, there is likely range expansion and increases in abundance. It is classified as Threatened; its status should be reviewed.
