This species was originally distributed throughout south-east USA, but in 1999 was limited to c.30 isolated populations (the largest in South Carolina and Florida), totalling c.4,700 groups or c.11,000 individuals and occupying just 4,000 km^23,4,5. Between 1980-1990, it declined by at least 23%, with 50% of groups in just six populations⁶. However, the most recent data suggests that the population may now be stable or increasing^15,16.
