There are six existing populations and three of them consist of multiple ponds that are hydrologically connected. Most of the populations are on protected parkland, but they may still be subject to some disturbance. There are two historical populations from the 1920s that have not been resurveyed.
Most of the populations have been surveyed at least twice and their short-term trend seems to be stable. However, fluctuating water levels make understanding the exact trend difficult.
The long-term trend appears stable as there are as many or even more populations now than were known in the past. This is a result of more detailed surveys in the 1980s and the protection of many of the coastal plain ponds.
