Short-term response to burning was moving off area by most harvest mice, southern bog lemmings, and prairie 

 voles; deer mice moved onto burned area.

 101:611-613. 



Three specimens of SYNAPTOMYS BOREALIS for Maine and one for New Hampshire are reported. On 

 18-20 July 1 immature female and I adult female (4 embryos) were captured in pitfalls (117 sherman live trap- 

 nights, 108 pitfall trap-nights). Both were captured at 1375 m in a wet sedge meadow dominated by CAREX, 

 sphagnum moss, lichen (CETRARIA NIVALIS), SALIX UVA-URSI, and BETULA GLANDULOSA. 

 Associated species at the site were MICROTUS PENNSYLVANICUS, CLETHRIONOMYS GAPPERI, 

 PEROMYSCUS MANICULATUS, BLARINA BREVICAUDA, and SOREX CINEREUS. A single immature 

 male SYNAPTOMYS BOREALIS was captured on 1 1 Aug in a stand of dead fir and spruce at 400 m 

 elevation. Understory was dominated by fir, spruce, mountain ash, and paper birch; shrub and ground layer was 

 dense raspberry, ferns, some grass and sedge, and sphagnum in scattered damp areas. The area was trapped in 

 1982 (360 trap-nights), July 1985 (135 Longworth live trap-nights) and Aug 1985 (300 snap trap-nights). Other 

 mammals at this site included MICROTUS CHROTORRHINUS, M. PENTvISYLVANICUS, 

 CLETHRIONOMYS GAPPERI, PEROMYSCUS MANICULATUS, and SOREX CINEREUS. There are now 

 a total of 7 specimens from 4 locations in Maine and New Hampshire.

Good reference for Minnesota sensitive species with state maps with county of occurrence, status and basis for 

 status, habitat, identification, recommendations, and selected references. SYNAPTOMYS BOREALIS 

 summarizes the 5 locations in N NfN where lemmings are known. Suggests the species may be difficult to trap. 

 Habitat given as dominated by sphagnum and graminoids; may include forested bogs or open ericaceous 

 shrublands over total range. Recommend additional sampling by qualified professionals and preservation of 

 large tracts of peatlands.

For SYNAPTOMYS BOREALIS: description and measurements; Habitat: usually wet alpine and subalpine 

 meadows; runways and burrows well defined; moves to higher ground in winter; eats sedges, grasses, 

 saxifrages, and other plants; makes small piles of cuttings in runways; deposits droppings in special places 

 where 2 cupflils may accumulate; 2-8 young per litter, usually 4-5; young bom May-Aug; winter nest of dry 

 grass 8" diameter; no citations for any of this information.

For SYNAPTOMYS BOREALIS: On 28 June found a colony in muskeg and 4 were taken. Habitat was 50 feet 

 square and the "mossy carpet was honeycombed with tunnels." Fecal pellets were strewn about the tunnels, 

 concentrated where feeding was occurring. 1-1 .5 inch cuttings of grass were piled throughout the colony. Also 

 caught here were MICROTUS PENNSYLVANICUS. Measurements.
