Ground squirrel
From Memory Alpha, the free Star Trek reference
A ground squirrel is small Earth mammal from North America.
Noah Lessing compared the landscape of a plant located in the Delta Quadrant to McKinley Park, where he described an area on that planet as being a place where a family of ground squirrels once lived, and that right next to it was a patch of poison ivy. (VOY: "Equinox, Part II")
