New Hampshire’s 18 rock vole records are a northern county’s story: Coos County, the big, high county above the notches, holds 14 of them. This is a vole of cool, mossy boulder fields and rocky spruce-fir slopes, and New Hampshire’s version of that country is the White Mountains. Four records come from along the Appalachian Trail corridor, where hikers and researchers cross exactly the talus this vole calls home.
Boulder fields, not valley parks
The suggested viewing parks sit far to the south, and Pawtuckaway and Monadnock are fine rocky hills, but the verified records cluster around Franconia Notch and the high Whites. That mismatch is worth heeding. Rock voles live where talus stays cool and damp under a skin of moss, and in New Hampshire that means elevation. A mossy boulder field in the high Whites is a far better bet than a ledge in the southern tier.
A summer survey window
All 18 records fall between June and September, with August leading at 8. Rock voles don’t hibernate; they work their talus year-round, much of it under snow. The summer bunching reflects when mountain traplines run and when hikers are on the rocks, not a seasonal appearance.
Status in New Hampshire
NatureServe ranks the rock vole S4, apparently secure, in New Hampshire, and it’s native here. Secure doesn’t mean easy to find. This vole lives in scattered pockets, turns up in ones and twos, and goes unnoticed wherever nobody sets a trap among the boulders.
