CountyRecords
Pend Oreille County 1

The complete county distribution, spread across 1 Washington counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Washington’s long-legged myotis record since 2000 comes down to a single GBIF report, from Pend Oreille County in the state’s northeast corner.

One record can’t map a range. Unlike some of its close relatives, the long-legged myotis isn’t tied to the wet coastal belt or the high Cascades alone; across the West it’s a bat of dry pine forest, canyon country, and mountain meadow alike. NatureServe ranks it vulnerable in the state, a standing that owes as much to how easily bats slip past documentation as to any measured decline.

The lone record is from July, when bats are most active and survey crews are out with nets and detectors. The empty months are a blind spot, not evidence the bats are gone.
