The complete county distribution, spread across 3 Oregon counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Oregon has just 6 long-legged myotis records from 2000 on, 4 of them iNaturalist observations. Half come from Oregon Caves National Monument and Preserve in Josephine County, with 2 from Lake County in the south-central high desert and 1 from Jackson County.

Caves and conifer edges

Long-legged myotis is a mountain forest bat, recorded most heavily between 5,200 and 7,900 feet in coniferous forest, mixed conifer, and streamside corridors elsewhere in its range. The forested Siskiyou Mountains around Oregon Caves offer a version of that close to home, with conifer cover, streams, and sheltered rock where bats can roost.

Records fall between June and September, with August holding half of them, but 6 records are too few to show a seasonal pattern.

NatureServe ranks the long-legged myotis S3, Vulnerable, in Oregon, against a G4 status globally, and the species is treated as native to its Oregon range.
