CountyRecords
Clark County 9
Nye County 1

The complete county distribution, spread across 2 Nevada counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Nevada has only 10 records for Ticul’s desert shrew: 9 from Clark County and 1 from Nye County, none tied to a named park or refuge. They show where people have reported it, not how many animals live there.

That puts nearly all of them in the state’s southern desert country rather than its higher central or northern ranges. Eight of the 10 are dated June through August, too few to show a real seasonal pattern.

All 10 are research-grade iNaturalist observations, and GBIF holds none. Those 10 records measure documented encounters, not Nevada’s population size. It’s native to Nevada. Nevada doesn’t specifically list it under the state’s conservation framework, and the IUCN hasn’t evaluated its global risk.
