The following efforts were for 6 d unless abbreviated due to disturbance by carnivores: monitored (M) sites in VNP (Table 2), and sites inventoried for eastern heather vole (Phenacomys ungava) and northern bog lemming (Synaptomys borealis) (see below).
No rock vole was taken on any of the 25 bogs inventoried for the northern bog lemming.
Sparks used mousetraps in March 2007 to capture 42 small mammals, white-footed mouse (14 individuals), prairie deer mouse (8), house mouse (8), prairie vole (4), meadow vole (4), and southern bog lemming (1).
The higher numbers for the least shrew and the bog lemming at Goose Pond are probably, at least partly, attributable to the fact there is a great deal of dry open grassland at Goose Pond.

are readily identifiable to species.
The proposed park shelters moose, peregrine falcons, spruce grouse, loons, northern bog lemmings
, and pine martens now, and the area once provided habitat for wolves, lynx, and catamounts.
Distribution and status of the southern bog lemming, Synaptomys cooperi, in southeastern Virginia.
Despite broad distributions in eastern North America, southern bog lemmings (Synaptomys cooperi) and woodland voles [Microtus (Pitymys) pinetorum] are less studied than other arvicoline rodents, primarily because their populations are patchy, often intermittently present, and usually low in density.
Likewise, Synaptomys cooperi is seldom taken, partly because it is not generally attracted to bait, and partly because, despite its name (bog lemming), it is usually found in dry grassy fields, especially of little bluestem.
A total of 121 small mammals was trapped at the Crane Division, Naval Surface Warfare Center (NSWC Crane), Glendora Site, Sullivan County, Indiana, including 54 least shrews (Cryptotis parva), 38 prairie voles (Microtus ochrogaster), 11 prairie deer mice (Peromyscus maniculatus bairdii), 7 bog lemmings (Synaptomys cooperi), 6 meadow voles (Microtus pennsylvanicus), and 5 white-footed mice (Peromyscus leucopus).
All of these vertebrates presently occur in Mackinac County, Michigan, with the exception of the Northern Bog Lemming
, Synaptomys cf.
The southern bog lemming is a small vole that occurs in the northeastern portion of North America, extending as far west as Kansas and Nebraska (Linzey, 1983; Linzey and Cranford, 1984).
gossii Coues, 1877 "southern bog lemming" (Rodentia: Muridae).
Rand & Rand (1951) reported skeletal remains of 32 species of mammals in blowouts in Indiana Dunes State Park, including 26 species still present: opossum, masked shrew, northern short-tailed shrew, eastern mole, silver-haired bat, big brown bat, eastern red bat, eastern cottontail rabbit, eastern chipmunk, woodchuck, thirteen-lined ground squirrel, Franklin's ground squirrel, fox squirrel, red squirrel, southern flying squirrel, white-footed and prairie deer mouse, meadow vole, muskrat, southern bog lemming
, Norway rat, house mouse, raccoon, least weasel, long-tailed weasel, mink and striped skunk.
Although no statistical analysis was conducted, we noted that the majority of the medium-sized small mammals (meadow voles, southern red-backed voles, southern bog lemmings
) captured in pitfalls were juveniles.
