• Abstract: Summary of field data collected in survey of small mammals and amphibians in old- 

 growth coniferous forests on the Priest Lake Ranger District , Idaho Panhandle National Forests. 

 Abundance and species richness were estimated on pitfall trapping grids with drift fences at 1 5 

 sites representing five replicates of three treatments. 5 shrew species, 1 pocket gopher sp., 6 sp. of 

 mice and vole (including Northern Bog Lemmings) , and 3 amphibian sp. were found over a three 

 year period.

• A single adult male was captured on 14 July 1988 at Cow Creek, Boundary Co., Idaho at 1304 m 

 elevation. The site was at the edge of a sphagnum bog next to an Englemann spruce tree. 

 Dominant vegetation in the bog included: DESCHAMPSIA CAESPITOSA. CAREX 

 ROSTRATA, ERIOPHORUM CHAMISSONIS, BETULA GLANDULOSA, KALMIA 

 MICROPHYLLA, and SPHAGNUM spp. Other small mammals captured at the site included: 

 ZAPUS PRINCEPS, CLETHRIONOMYS GAPPERI, SOREX spp, TAMIAS RUFICAUDUS, 

 and MICROTUS PENNSYLVANICUS. The lemming was taken during 2 nights of trapping with 

 32 museum special snap traps and 16 pitfalls . The other Idaho SYNAPTOMYS site on Gold Peak 

 Road (Johnson and Cheney 1953) was re-sampled in 1987 but no SYNAPTOMYS taken; it was 

 logged sometime between the original capture and the re-trapping attempt in 1987. States that 

 records of SYNAPTOMYS BOREALIS captured by Larrison (Larrison 1967; Larrison and 

 Johnson 1981) were actually misidentified PHENACOMYS INTERMEDIUS.

 Alaska. Arctic 21:223-244. 



• SYNAPTOMYS BOREALIS is currently present at the site but was not found in Late Pleistocene 

 deposits. Guthrie is unsure if it is a post-glacial immigrant or was present but not found.

• Good for synonymies, distribution, subspecies, key, and citations of original descriptions. For 

 SYNAPTOMYS BOREALIS: places in subgenus MICTOMYS and lists 9 subspecies and their 

 distributions. Gives external measurements as totakl 18 -135; tail:19-27; hind foot:I6-22; ear:12-
