New Mexico is one of just three states where the dwarf shrew is known to occur, alongside Colorado and Utah, and it sits near the southern tip of this tiny insectivore’s range here. NatureServe rates it S2, Imperiled, in New Mexico, reflecting how thin and patchy its high-country habitat is in the state. Carson National Forest, Gila National Forest, and Lincoln National Forest, the three places tied to its records, are all mountain forest blocks that match its need for cool, moist ground litter.
Records concentrate almost entirely in July and August and fall to nearly nothing the rest of the year, which likely tracks when high-elevation surveys happen rather than any real seasonal shift in the shrew itself.
