Introduced and invasive status

Introduced in Ohio: iNaturalist (opens in a new tab)

Also listed

  • Introduced and assessed as invasive in the lower 48 states (listed as Mus musculus)

iNaturalist's volunteer curators list it as introduced in their Ohio checklist.

US-RIIS assesses a species as invasive when it causes, or is likely to cause, harm there, or is at least locally abundant and harmful ecologically, economically, or to health.

Status: Simpson A, Sellers E, Pagad S (2023). United States Register of Introduced and Invasive Species (US-RIIS), ver. 2.0. U.S. Geological Survey, https://doi.org/10.5066/P9KFFTOD (opens in a new tab)

What these results show

These results show when people recorded a species, not when or where it occurs. Missing weeks and low counts do not mean absence or scarcity, and counts are not abundance. Contributed records reflect where, when and what people chose to observe.
