Florida Salt Marsh vole (Microtus pennsylvanicus dukecampbelli)
Where Listed: WHEREVER FOUND
The Florida salt marsh vole is a small (178 to 198 millimeters in total length), short-tailed rodent with a blunt head and short ears. Its fur is black-brown dorsally and dark gray ventrally. It is closely related to the meadow vole (M. p. pennsylvanicus) but can be distinguished by its larger size, darker coloration, relatively small ears, and by certain skull characteristics.

» Life History
The Florida salt marsh vole lives in periodically flooded high salt marsh zone where it is believed to survive high tides and storm flooding by climbing vegetation and swimming. It appears to be most common in areas vegetated by seashore saltgrass (Distichlis spicata).
Like most species of Microtus, it probably feeds mainly on green plant materials, especially grasses.
Movement / Home Range
The Florida salt marsh vole is known only from one site at Waccasassa Bay in Levy County, Florida, where it appears to exist in low numbers and has a very restricted range. Any natural or human-caused adverse impact to this species could result in its extinction.
The Florida salt marsh vole is believed to represent a relict population of the widespread meadow vole (Microtus pennsylvanicus) which was much more widespread in Florida during the Pleistocene. The range of the species in Florida is believed to have been greatly reduced as climatic change resulted in vegetational changes from grassland to forest in Florida. The current restricted population is threatened by storm surges association with hurricanes and tropical storms, the loss of coastal marshes due to flooding from rising sea level, and potentially by any human-caused alterations that might be proposed for these salt marshes.
